34f52ed08e Improve the LPM module:
* Implement new style of PD locks
* Use our own shutdown sequence rather than the one provided by cc26xxware
* Shutdown from within the interrupt that requested it. This allows shutdown to take place even if the code is stuck in a loop somewhere else
* Improve DCDC/GLDO/uLDO switching logic
* Explicitly handle oscillators and retentions

421fbfae25 Change the LPM locks API:
Instead of using a separate data structure to request that a PD remain powered during deep sleep,
we do the same within the main LPM data structure through an additional field.

This allows us to maintain only one linked list of LPM modules and overall improves code clarity

3b6d9e5a64 mc1322x: remove rest tutorial
This tutorial was written for the older implementation of CoAP, and
while it may be possible to update it, the directions include URLs and
repos that no longer exist, so it's better to just remove it.

3d9d52de87 cc2538: gpio: Fix missed interrupts
Only the interrupt flags that have been handled must be cleared.
Otherwise, if a new interrupt occurs after the interrupt statuses are
read and before they are cleared, then it is discarded without having
been handled. This issue was particularly likely with two interrupt
trigger conditions occurring on different pins of the same port in a
short period of time.

1a5632cba0 cc2538: gpio: Fix missed power-up interrupts
Power-up interrupts do not always update the regular interrupt status.
Because of that, in order not to miss power-up interrupts, the ISR must
handle both the regular and the power-up interrupt statuses.

1e67ab3941 cc2538: gpio: Add macros to get interrupt status
Introduce new useful GPIO macros to:
 - get the raw interrupt status of a port,
 - get the masked interrupt status of a port,
 - get the power-up interrupt status of a port.

These macros are cleaner and less error-prone than raw register access
code copied all over the place.

7b3e80a957 Remove received packet(s) to allow to send one.
Behave just like the CS8900A driver: Both the CS8900A and the LAN91C96 dynamically share a buffer for received packets and packets to be send. If the chip is exposed to a network with a lot of broadcasts the shared buffer might fill quicker with received packets than the 6502 reads them (via polling). So we might need to drop some received packets in order to be able to send anything at all.

19fd7a3551 Use additive offsets
OR-ing an offset to a base address instead of adding it is dangerous
because it can only work if the base address is aligned enough for the
offset.

Moreover, if the base address or the offset has a value unknown at
compile time, then the assembly instructions dedicated to 'base +
offset' addressing on most CPUs can't be emitted by the compiler because
this would require the alignment of the base address against the offset
to be known in order to optimize 'base | offset' into 'base + offset'.
In that case, the compiler has to emit more instructions in order to
compute 'base | offset' on most CPUs, e.g. on ARM, which means larger
binary size and slower execution.

Hence, replace all occurrences of 'base | offset' with 'base + offset'.
This must become a coding rule.

Here are the results for the cc2538-demo example:
 - Compilation of uart_init():
    * before:
        REG(regs->base | UART_CC) = 0;
        200b78:	f446 637c 	orr.w	r3, r6, #4032	; 0xfc0
        200b7c:	f043 0308 	orr.w	r3, r3, #8
        200b80:	2200      	movs	r2, #0
        200b82:	601a      	str	r2, [r3, #0]

    * now:
        REG(regs->base + UART_CC) = 0;
        200b7a:	2300      	movs	r3, #0
        200b7c:	f8c4 3fc8 	str.w	r3, [r4, #4040]	; 0xfc8

 - Size of the .text section:
    * before:	0x4c7c

919b6919a5 Fixed hardware detection.
The previous chip detection was inspired by the old IP65 driver code. For some reason it didn't work as expected. The new code is simpler and based on this statement in the chip datasheet: "The upper byte always reads as 33h and can be used to help determine the I/O location of the LAN91C96."

705587cdb7 Fix time accounting on msp430 Series 1 and Series 2 MCU based platforms.
The problem with the current version of the code was that the condition at the end of the do...while loop at Timer A1 interrupt:
 while((TACCR1 - TAR) > INTERVAL);
evaluates to false whenever TACCR1 == TAR.
Not incrementing TACCR1 in this case leads to Timer A1 interrupt not being called for 2 seconds, until TAR counter reaches TACCR1 again after an overflow.

The patch avoids this problem by changing the condition of the loop, and using CLOCK_LT macro to compare between time values.

The patch also attempts to fix another problem: a read of TAR register while it is being updated may return a lower value than the actual contents. To avoid that, the "read twice and compare results" idiom should be used. As the TAR register is updated by the actual hardware, it is of no importance whether it is read with interrupts disabled or enabled; the problem can occur in both contexts.

a5d7a06027 Enhanced Ethernet drivers.
Made Ethernet drivers easier to consume by assembly programs.
* Replaced function pointers with JMP instructions.
* Provide return values additionally via Carry flag.

Reset Ethernet chips on initialization.
Both for the CS8900A and the W5100 the data sheets just say that
the RESET bit is automatically cleared after the RESET. This may
be interpreted in two ways:
1) There's no need to be afraid of reading the RESET bit as 1 and
unintentionally trigger a RESET by writing it back after ORing in
some other bit.
2) The RESET process isn't complete before the RESET bit hasn't
become 0 again.
It's impossible for me to empirically falsify the latter option
as the drivers are supposed to work on faster machines than the
ones I have access to. And if the RESET process includes things
like oscillators then the time to complete the RESET could differ
even between multiple exemplars of the same chip. Therefore I
opted to presume the latter option.
However that means a non-exsistent chip may cause an infinite
loop while waiting for the RESET bit to be cleared so I finally
added code to detect the presence of the Ethernet chips. There's
a risk of a chip being locked up in a way that makes the detection
fail - and therefore the RESET not being performed. This catch-22
needs to be solved by the user doing a hard RESET.

af27d2d252 [CC2538-SPI] Implement SPI_FLUSH, spi mode, !CS
Because the CC2538 has a multi-byte SPI RX FIFO, flushing the buffer
requires more than just a single read. This adds a loop that empties the
entire RX buffer on a FLUSH().

Different SPI chips needs different SPI settings. This commit adds a
function that allows chip drivers to configure the SPI peripheral before
using it.

The frame pin the driver was using as a chip select does not work as
most devices expect it to. It toggles after every byte, and most chips
interpret that as end of message. To make drivers more reliable, each
chip driver should setup a GPIO and assert it as needed.

eed1352282 Fix CC2538 random_init lockup
Contiki sometimes fails to boot correctly and locks up in
random_init()

This problem only manifests itself for specific versions
of the arm-gcc toolchain and then again only for specific
levels of optimisation (-Os vs -O2, depending on the
value of the SMALL make variable)

The lockup is caused when we write an RFCORE XREG before
the RF clock ungating has taken effect, which in turn
only occurs depending on the assembly generated for those
two instructions:

  REG(SYS_CTRL_RCGCRFC) = 1;

  REG(RFCORE_XREG_FRMCTRL0) = 0x00000008;

This commit makes the RNG wait for the ungating to take
effect before attempting to write the register

68b65e6c47 Fix CPU clock calibration in msp430f2xxx based platforms (e.g. Zolertia Z1).
The following problems were present in the existing DCO calibration algorithm:

Problem #1. In function msp430_quick_synch_dco(), the "for(i=0; i < 1000; i++) { .. }" loop is optimized away by the compiler, as i is not volatile. Making i volatile would improve the results, but would not be sufficient: see the next point.

Problem #2. According to MSP430F2617 Device Erratasheet, bug BCL12 precludes a naive implementations of "fast" calibration altogether. The bug is present on all MCU revisions up to date.

The description of the bug:
"After switching RSELx bits (located in register BCSCTL1) from a value of >13 to a value of <12 OR from a value of <12 to a value of >13, the resulting clock delivered by the DCO can stop before the new clock frequency is applied. This dead time is approximately 20 us. In some instances, the DCO may completely stop, requiring a power cycle.

Furthermore, if all of the RSELx bits in the BSCTL1 register are set, modifying the DCOCTL register to change the DCOx or the MODx bits could also result in DCO dead time or DCO hang up."

In Contiki code for msp430f2xxx @ 8MHz, the RSEL search currently typically goes from 15 down to 11, thus violating the rules.

Step-by-step RSEL change is proposed as the best possible workaround:
"[..] more reliable method can be implemented by changing the RSEL bits step by step in order to guarantee safe function without any dead time of the DCO."

Problem #3. The old Contiki code started from the highest possible calibration values: RSEL=15, DCOx=7. According to MSP430F2617
datasheet, this means that the DCO frequency is set to 26 MHz. For one, Vcc under 3V is not supported for this frequency, so this means that battery-powered nodes have a big problem. The minimal operating voltages are:
- 1.8V for RSEL <= 13
- 2.2V for RSEL = 14
- 3.0V for RSEL = 15
So the correct way is to always start calibration from RSEL <= 13, unless explicityly pre-calibred values are present.

Problem #4. Timer B should be turned off after the calibration, following the "Principles for Low-Power Applications" in MSP430 user's Guide.

The patch fixes these issues by performing step-by-step calibration and turning off Timer B afterwards. As opposed to MSP430F1xxx calibration, this algorithm does not change the ACLK divider beforehand; attempts to make calibration more precise would lead to looping in some cases, as the calibration step granularity at larger frequencies is quite big.

Additionally, the patch improves DCOSYNCH_CONF_ENABLED behavior, allowing the resynchronization to correct for more than one step.

Instead, this change adds TARGET_LIBFILES to the correct location, like most

7f48057b9e leds: Fix the API
The leds API did not work in some cases. E.g. with the following sequence:
  leds_off(LEDS_ALL);
  leds_toggle(LEDS_GREEN);
  leds_off(LEDS_ALL);
the green LED was remaining on after the last call.

This was caused by the toggle feature made synonymous with the invert feature,
although it is unrelated. leds_toggle() is indeed supposed to toggle an LED,
while leds_invert() is supposed to change the active level of an LED. However,
all users of leds_invert() actually meant leds_toggle(), and the invert feature
does not make sense in this module because it is not handy due to successive
calls to leds_invert() changing the intended behavior, and hardware active
levels should be managed in leds_arch_set() (e.g. by XORing the passed value
with a hardware-specific constant before setting the output levels of the pins).

Consequently, this change:
 - removes the leds_invert() function,
 - makes leds_toggle() behave as expected relatively to leds_off() / leds_on(),
 - sanitizes the code in the leds module.

37e73894f1 cc2538: Move SoC data to a dedicated section to save space
Some SoC data requires huge alignments. E.g., the µDMA channel control table has
to be 1024-byte aligned. This table was simply aligned to 1024 bytes in the C
code, which had the following consequences, wasting a lot of RAM:
 - As this table could be placed anywhere in .bss, there could be an alignment
   gap of up to 1023 bytes between the preceding data and this table.
 - The size of this table was also aligned to 1024 bytes, regardless of
   UDMA_CONF_MAX_CHANNEL, making this configuration option supposed to save RAM
   just useless.
 - .bss was also aligned to at least 1024 bytes, creating a huge alignment gap
   between .data and .bss.

Instead of relying on the compiler to force this alignment, and on the linker to
automatically place data, this change places carefully such SoC data in RAM
using the linker script. A dedicated section is created to place such SoC data
requiring huge alignments, and it is put at the beginning of the SRAM in order
to ensure a maximal alignment without any gap. In this way, the alignment of
.bss also remains normal, and the size of this table is not constrained by its
alignment, but only by its contents (i.e. by UDMA_CONF_MAX_CHANNEL).

In the case of the µDMA channel control table, the data is still zeroed by
udma_init() (instead of also being zeroed as part of .bss).

ab4b955f17 cc2538: Sort link input sections by alignment to optimize size
Normally, the linker does not sort files and sections matched by wildcards, so
they are placed in the order in which they are seen during link. If numerous
objects with different alignments are mixed, or if objects with unusually large
alignments are present, this very likely leads to a lot of space being wasted
because of accumulated alignment gaps.

This commit forces input sections to be sorted by alignment (unless this is
overridden by the linker script), which decreases the number and the size of
alignment gaps, thus saving space.

For a typical Contiki project, this change saves nearly 1 kiB, mainly in .bss.

Note that this behavior is only enabled if the SMALL make variable is set to 1,
because this makes more sense for a size optimization.

e1147ec787 cc2538: Set the type of the .nrdata output section to NOLOAD

application, and not be automatically done by the startup code. It should
neither be zeroed like .bss, nor be initialized from data in flash memory like

.nrdata was not set to NOLOAD, causing the generated ELF .nrdata section header

d86b8275ec cc2538: clock: Fix time drift occurring with PM1/2
The clock adjustments made when waking up from PM1/2 were very inaccurate. If
relying on ContikiMAC's rtimer to sleep, this led to Contiki's software clock
time, seconds and etimers to be 2.5 s slower after each min, i.e. 1 hour slower
after each day, which is a show stopper issue for most real-life applications.

This was caused by a lack of accuracy in several pieces of code during sleep
entry and wake-up:
 - It was difficult to synchronize the calls to RTIMER_NOW() before and after
   sleep with the deactivation and activation of the SysTick peripheral caused
   by PM1/2. This caused an inaccuracy in the corrective number of ticks passed
   to clock_adjust().
 - The value passed to clock_adjust() was truncated from an rtimer_clock_t
   value, but the accumulated error caused by these truncated bits was ignored.
 - The SysTick peripheral had to be stopped during the call to clock_adjust().

Rather than creating even more complicated clock adjustment mechanisms that
would probably still have mixed results as to accuracy, this change simply uses
the Sleep Timer counter as a base value for Contiki's clock and seconds
counters. The tick from the Systick peripheral is still used as the interrupt
source to update Contiki's clocks and timers. When running, the SysTick
peripheral and the Sleep Timer are synchronized, so combining both is not an
issue, and this allows not to alter the rtimer interrupt mechanism using the
Sleep Timer. The purpose of the Sleep Timer is to be an RTC, so it is the
perfect fit for the clock module, all the more it can not be disturbed by PM1/2.
If the 32-kHz XOSC is used, the Sleep Timer is also very accurate. If the
32-kHZ RCOSC is used, it is calibrated from the 32-MHz XOSC, so it is also
accurate, and the 32753-Hz vs. 32768-Hz systematic error in that case is
negligible, all the more one would use the 32-kHz XOSC for better accuracy.

Besides fixing this time drift issue, this change has several benefits:
 - clock_time(), clock_seconds() and RTIMER_NOW() start synchronized, and they
   change at the same source pace.
 - If clock_set_seconds() is called, then clock_seconds() indicates one more
   second almost exactly one second later, then exactly each second. Before this
   change, clock_seconds() was not synchronized with clock_set_seconds(), so the
   value returned by the former could be incremented immediately after the call
   to the latter in some cases.
 - The code tied to the clock module is simpler and more robust.

b7515004da cc2538: clock: Fix secs update in clock_adjust()
Whole elapsed seconds are added to secs first, so only the remaining subsecond
ticks should then be subtracted from second_countdown in order to decide whether
secs should be incremented again.

Otherwise, secs is not correctly updated in some cases, typically if the bit 7
of ticks is 1. E.g., with ticks = 128 (i.e. exactly 1 s elapsed) and
second_countdown = 128, secs was first incremented as expected, then 128 was
subtracted from second_countdown, giving 0 and triggering an unwanted second
increment of secs. Or with ticks = 129 (i.e. 1 s + 1 tick) and
second_countdown = 1, secs was first incremented as expected, then 129 was
subtracted from second_countdown, giving 128 and missing a second increment of
secs that should have occurred because second_countdown wrapped around.

28a563a24b cc2538: clock: Request an etimer poll in clock_adjust()
During PM1+, the hardware timer used to implement the Contiki clock is frozen,
so clock_adjust() needs to be called when exiting those modes in order to
compensate for the clock ticks missed while the timer was frozen. Doing so
changes the Contiki clock time, so etimer_request_poll() needs to be called in
order to inform the etimer library that an etimer might have expired.

Note that waiting for the next clock ISR to call etimer_request_poll() is
unreliable because the system might go back to sleep beforehand.

5261bb861d cc2538: lpm: Fix RTIMER_NOW() upon wake-up
When returning from PM1/2, the sleep timer value (used by RTIMER_NOW()) is not
up-to-date until a positive edge on the 32-kHz clock has been detected after the
system clock restarted. To ensure an updated value is read, wait for a positive
transition on the 32-kHz clock by polling the SYS_CTRL_CLOCK_STA.SYNC_32K bit,
before reading the sleep timer value.

Because of this RTIMER_NOW() fixup, lpm_exit() has to be called at the very
beginning of ISRs waking up the SoC. This also ensures that all clocks and
timers are enabled at the correct frequency and updated before using them
following wake-up.

Without this fix, etimers could sometimes (randomly, depending on timings)
become ultra slow (observed from 10x to 40x slower than normal) if the system
exited PM1/2 very often. This issue occurred more often with PM1.

by the 16-MHz RCOSC startup time.

a2686e581e cc2538: Add header file for flash CCA page and use it
Create a dedicated header file with all the definitions for the flash lock bit
page and customer configuration area. This avoids duplicating those definitions
in the startup-gcc.c files of all CC2538-based platforms, and this also allows
to easily manipulate the CCA from outside startup-gcc.c (e.g. for on-the-air
firmware update).

The definitions are now complete contrary to what was in startup-gcc.c:
 - Definitions have been added to select the bootloader backdoor pin and active
   level if enabled.
 - Definitions have been added to access the page and debug lock bits. The debug
   lock bit can be used to prevent someone from reading back a programmed
   firmware through JTAG if the firmware binary image has to be confidential,
   which should be combined with a disabled bootloader backdoor.
 - The application entry point is now tied to the beginning of the .text section
   instead of to the beginning of the flash. This allows projects using custom
   linker scripts to place the application entry point anywhere in the flash,
   which can be useful e.g. for on-the-air firmware update.

680050861c cc2538: gpio: Use accessor macros
Use the GPIO accessor macros instead of copying raw register access code all
over the place. This is cleaner and less error prone.

This fixes the setting of the USB pull-up resistor that worked only by chance on
the CC2538DK because it is controlled by the pin 0 of the used GPIO port.

923f161b7b cc2538: gpio: Add pin read / write and interrupt clear macros
Introduce new useful GPIO macros to:
 - read the levels of some port pins,
 - write the levels of some port pins (pass bit-field value to be set),
 - clear the interrupt flags for some port pins.

These macros are cleaner and less error prone than raw register access code
copied all over the place.

d35732505b cc2538: lpm: Add registration mechanism for peripherals
Some peripherals have their clocks automatically gated in PM1+ modes, so they
cannot operate. This new mechanism gives peripherals a way to prohibit PM1+
modes so that they can properly complete their current operations before
entering PM1+.

This mechanism is implemented with peripheral functions registered to the LPM
module. These functions return whether the associated peripheral permits or not
PM1+ modes. They are called by the LPM module each time PM1+ might be possible.
If any of the peripherals wants to block PM1+, then the system is only dropped
to PM0.

f34731c1a9 cc2538: spi: Do not call SPI_WAITFOREORx() at end of init
If the SSI has never been used and spi_init() is called, then the SSI receive
FIFO is empty and remains so, so calling SPI_WAITFOREORx() at the end of
spi_init() waits endlessly for SSI_SR.RNE to be set. Hence, this call must be
removed in order to avoid a deadlock.

974850cdf2 cc2538: Generate .hex output
ELF files generated by GCC make SmartRF Flash Programmer 2 crash (only the TI
format is supported by this tool for ELFs), and binary files are not very
appropriate because they are gapless, so generate Intel HEX files since these
are very well supported by most programming tools while still flexible.
