galileo: Initial support for Intel Galileo Platform This patch adds the initial support for Intel Galileo Platform. It contains the minimum set of code required to boot a dummy Contiki image. For Galileo initial support, we implemented a linker script, a minimal bootstrap code, a set of stubbed functions required by newlib, and a very simple main() function. Moreover, we also define some header files and macros required by Contiki. To build applications for this platform you should first build newlib (in case it wasn't already built). To build newlib you can run the following command: $ platform/galileo/bsp/libc/build_newlib.sh Once newlib is built, you can build applications. To build applications for Galileo platform you should set TARGET variable to 'galileo'. For instance, building the hello-world application should look like this: $ cd examples/hello-world/ && make TARGET=galileo This will generate the 'hello-world.galileo' file which is a multiboot- compliant [1] ELF image. This image can be booted by any multiboot- complaint bootloader such as Grub. Finally, this patch should be used as a guideline to add the initial support for others platforms based on x86 SoCs.

galileo: Concentrate core implementations in platform/galileo/core/ Currently, it is common to see Contiki's core/ interfaces implementations spread in both cpu/ and platform/. We here take one step further starting an effort to centralize all of these in platform's code instead. This commit starts this by adding platform/galileo/core/ and its sys/ subfolder, adding a stubbed mtarch.h and moving clock and rtimer implementations to this new folder. From now on we should concentrate implementation from Contiki's core/ interfaces into the appropriate subfolder in platform/galileo/core/. Note that this is not the current fashion followed on other platforms and cpus folders, as most of them add the core interface implementation into its subfolder directly. For instance, on CC2538DK, core/dev/button-sensor.h is implemented in platform/cc2538dk/dev/ directly, while on Galileo it would sit at platform/galileo/core/dev/. We believe ours is a better approach to organize and escalate a platform's code base. We also remove previous x86 mtarch.h and mtarch.c since they weren't used at all - both native and cooja platforms have their own mtarch implementations.

CONTIKI_TARGET_MAIN = ${addprefix $(OBJECTDIR)/,contiki-main.o}
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.

CONTIKI_CPU=$(CONTIKI)/cpu/x86
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.

galileo: Override Ubuntu's default GCC flags to avoid link errors Ubuntu enables GCC's stack protector by default (see https://wiki.ubuntu.com/Security/Features). This causes link errors like the following: ...undefined reference to `__stack_chk_fail' To avoid these errors, this patch adds the "-fno-stack-protector" flag to both the CFLAGS used by the Contiki build process and the CFLAGS used by the newlib build process.
