* Enforce compilation without system headersStefan Reinauer2016-02-031-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces HOST_CPPFLAGS to be used for all objects being compiled with HOSTCC rather then the target compiler. Since glibc is not linked into the EC, no glibc include files should be included in the EC code base. Hence, create local definitions for clock_t and wchar_t that match what the glibc include would have done, and remove some unneeded includes. Due to very eager optimization, we have to give gcc a little notch to not kick out memset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The linker scripts are passed through the preprocessor so that they can distinguish between RO and RW images. This change makes the same macros available when compiling, so that code can contain directives like #ifdef SECTION_IS_RO or #define FW_SIZE_(section) CONFIG_##section##_SIZE #define FW_SIZE(section) FW_SIZE_(section) int size = FW_SIZE(SECTION); BUG=none BRANCH=none TEST=make buildall Nothing uses this yet, so there's no change to the images.

* cr50: add plumbing for signing CR50 RO imagesVadim Bendebury2015-08-251-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The signer utility needs to be built and the flat image needs to be signed. The signer utility is written in C++, supporting this required adding a new make command to Makefile.rules and a build file for the utility. The signing now needs to be a part of generating the .flat file. To achieve this an alternative set of rules is defined in Makfile.rules for targets where RO image needs to be signed. Rules for converting elf to hex have been consolidated as there is no need to omit the --set-section-flags when it does not apply.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces the build infrastructure changes needed for creating a shared RO library. (libsharedobjs). The end goal is for the library to contain various objects that can be shared with both the RO and RW EC images. Now, there are 3 make goals: ro, rw, and libsharedobjs. In order for changes that are only specific to a single image (ie: RW only) to be applied correctly, the object files are now built separately for the RO, RW, shared objects library targets. NOTE: Certain EC targets are incompatible with this model due to the fact that only one image is present within flash at a time.

* Add uppercase defined constants for BOARD_, CHIP_, etc.Randall Spangler2013-12-091-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, per-board defines use mixed case (BOARD_pit). This causes the presubmit script to complain because that's a style violation. Using --no-verify to bypass that also allows other style violations to creep in. This change adds uppercase variants (BOARD_PIT). It also adds a CORE_ define with '-' changed to '_', since CORE_cortex-m isn't a valid symbol but CORE_CORTEX_M is (so now we can #ifdef CORE_CORTEX_M). This does not remove the old mixed-case defines yet, nor does it find/replace them in the C source files. This is intentional, so this change can be cherry-picked into branches without needing to change files in the branch that may have picked up new #ifdefs. I will rename the constants in the C source files and remove the old mixed-case defines in a follow-on CL, which should not need to get picked into existing branches.
