2015-03-18bootstate: use structure pointers for scheduling callbacksAaron Durbin
The GCC 4.9.2 update showed that the boot_state_init_entry structures were being padded and assumed to be aligned in to an increased size. The bootstate scheduler for static entries, boot_state_schedule_static_entries(), was then calculating the wrong values within the array. To fix this just use a pointer to the boot_state_init_entry structure that needs to be scheduled. In addition to the previous issue noted above, the .bs_init section was sitting in the read only portion of the image while the fields within it need to be writable. Also, the boot_state_schedule_static_entries() was using symbol comparison to terminate a loop which in C can lead the compiler to always evaluate the loop at least once since the language spec indicates no 2 symbols can be the same value.

2015-03-17coreboot classes: Add dynamic classes to corebootFurquan Shaikh
Provide functionality to create dynamic classes based on program name and the architecture for which the program needs to be compiled/linked. define_class takes program_name and arch as its arguments and adds the program_name to classes-y to create dynamic class and compiler toolset is created for the specified arch. All the files for this program can then be added to program_name-y += .. Ensure that define_class is called before any files are added to the class. Check subdirs-y for order of directory inclusion. One such example of dynamic class is rmodules. Multiple rmodules can be used which need to be compiled for different architectures. With dynamic classes, this is possible.

2015-02-02src/arch/*/include/stdint.h: Provide definitions for bool typeAlexandru Gagniuc
Although bool normally belongs in stdbool.h, for our use cases, providing these definitions in stdint.h is acceptable.

2015-01-27CBMEM console: Fix and enhance pre-RAM supportKyösti Mälkki
Use the value of CONSOLE_PRERAM_BUFFER_SIZE to determine if we can do CBMEM console in bootblock and romstage. Kconfig forces it to zero if _BASE is unset or we cannot do CAR migration on x86. Add CBMEM console to bootblock, except for x86. Only one of bootblock and romstage clears the pre-RAM buffer. To start with empty console log on S3 wakeup, ramstage now clears previous contents of CBMEM buffer if there was no pre-RAM buffer. Unify Kconfig variable naming. TODO: ARM configurations do not define PRERAM_BUFFER_BASE values.

Until we completely can unify early_variables, use these to handle CBMEM update hooks for both romstage and ramstage. For x86, CAR_MIGRATE serves the purpose of romstage hooks.

2015-01-27vboot2: add verstageStefan Reinauer
This reverts the revert commit 5780d6f3876723b94fbe3653c9d87dad6330862e and fixes the build issue that cuased it to be reverted. Verstage will host vboot2 for firmware verification. It's a stage in the sense that it has its own set of toolchains, compiler flags, and includes. This allows us to easily add object files as needed. But it's directly linked to bootblock. This allows us to avoid code duplication for stage loading and jumping (e.g. cbfs driver) for the boards where bootblock has to run in a different architecture (e.g. Tegra124). To avoid name space conflict, verstage symbols are prefixed with verstage_. TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

There were a number of issues with the ARM64 build files. This patch ports the following changes from ARMV4/V7 to ARMV8: - make armv8 Kconfig options consistent with armv4/v7 - fix build include issues in boot.c, tables.c, and early_variables.h by matching armv4/v7.

There were instances of unneeded arch/hlt.h includes, various hlt() calls that weren't supposed to exit (but might have) and various forms of endless loops around hlt() calls. All these are sorted out now: unnecessary includes are dropped, hlt() is uniformly replaced with halt() (except in assembly, obviously).
