x86: Break Makefile.x86 into common and pc specific ones Now the cpu/x86/ provides a Makefile.x86_common and a Makefile.x86_pc. The former includes the common Makefile and adds legacy pc specific implementations (currently, drivers only) into the building context, while the latter has everything that defines the bootstrap of a x86 CPU. This commit also fixes platform/galileo/ so it includes the correct makefile - Makefile.x86_quarkX1000. Galileo uses a Quark X1000 SoC which is not an IBM Generic PC-like CPU, but it does provide most of a PCs peripherals through its "Legacy Bridge". Thus, it makes sense that QuarkX1000's Makefile includes code from the legacy_pc x86 cpu.

x86: Add Intel Quark X1000 UART support. This patch adds a driver that wraps the generic 16X50 UART driver with specific support for the two Intel Quark X1000 built-in UARTs.

x86: Use shared ISR for I2C and GPIO This patch permits interrupts to be generated by both the I2C and GPIO controllers for simultaneously-executing applications. The controllers share a single interrupt pin, INTC. Prior to this patch, quarkX1000_gpio_init() routed INTA to PIRQC and IRQ 10 (due to an incorrect assumption that INTA is connected to the GPIO controller), and quarkX1000_i2c_init() routed INTC to PIRQC and IRQ 9. The I2C controller initialization is a prerequisite for GPIO initialization, so the final configuration was that INTA and INTC were both routed to PIRQC and IRQ 10. Thus, only the GPIO ISR was being invoked, even if the I2C controller was actually responsible for the interrupt. This patch refactors the I2C and GPIO ISR setup and handler code so that the shared portions are combined in cpu/x86/drivers/legacy_pc/shared-isr.[ch]. The I2C and GPIO drivers communicate their interrupt information to the shared component by placing structures in a specific section of the binary.

x86, galileo: Add driver for Isolated Memory Regions (IMRs) The Intel Quark X1000 SoC includes support for Isolated Memory Regions (IMRs), which are specified using range registers and associated control registers that are accessible via the message bus. This patch adds a driver for accessing those registers.

x86: Move bootstrap code and linker script to cpu/x86 This is a refactoring patch, no functionality is changed. It moves loader.S and galileo.ld from platform/galileo/ to cpu/x86/ directory since they seem to be more SoC-specific than platform-specific. It also renames galileo.ld to quarkX1000.ld since it can be used by any platform based on Quark X1000 SoC, not only Galileo. Furthermore, this patch also renames loader.S to bootstrap_quarkX1000.S since it is pretty much a bootstrap code to any platform based on Quark X1000 SoC.

galileo: Fix Makefile.galileo This patch moves the compiler and linking options related to QuarkX1000 SoC to Makefile.x86_quarkX1000 since it is more suitable. For instance, '-m32' should be used in any platform based on QuarkX1000, not only Galileo. The same rationale applies for the others options (e.g. -march, mtune).

x86: Revise CFLAGS and LDFLAGS for LLVM Clang compatibility This patch slightly revises CFLAGS and LDFLAGS to specify the optimization and debugging options and linker script in a way that is compatible with using Clang as the C compiler and to invoke the linker (i.e. CC = clang and LD = clang).

x86, galileo: Add UEFI support This patch adds support for optionally building EFI binaries in addition to Multiboot ELF binaries. It includes a script, build_uefi.sh, that downloads tool and library sources from the EDK II project, builds the GenFw tool that is used to create UEFI binaries, and creates a makefile that is included from the main x86 common makefile and enables UEFI support in the Contiki build system. If the script is not run prior to building Contiki, then an informational message will be displayed with instructions for running build_uefi.sh if UEFI support is desired. This patch also adds the path to the auto-generated makefile to .gitignore. This patch modifies the linker script for the Intel Quark X1000 to account for the output file section offsets and alignment expectations of the EDK II GenFw project. This patch also adds a newlib patch to remove the weak symbol attribute from floating point stdio support routines. See <newlib>/newlib/README for an explanation of how the newlib developers intended for _printf_float and _scanf_float to be linked. Newlib declares them as weak symbols with the intention that developers would force them to be linked only when needed using a linker command line option. However, some but not all Contiki programs require them, so we cannot simply always include or exclude them. Instead, we remove the weak symbol attributes and rely on the linker to automatically determine whether or not they should be linked. This avoids an issue in which weak symbols were undefined in the intermediate DLL generated as part of the UEFI build process. That resulted in the GenFw program emitting "ERROR 3000" messages when it encountered relocations referencing such an undefined symbol. Finally, this patch updates README.md to both make some revisions to account for the UART support introduced in previous patches as well as to provide instructions for using the UEFI support.
