2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the architecture specific to that stage i.e. we will have CONFIG_ARCH variables for each of the three stages. This allows us to have an SOC with any combination of architectures and thus every stage can be made to run on a completely different architecture independent of others. Thus, bootblock can have an x86 arch whereas romstage and ramstage can have arm32 and arm64 arch respectively. These stage specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain and compiler flags for every stage. These options can be considered as either arch or modes eg: x86 running in different modes or ARM having different arch types (v4, v7, v8). We have got rid of the original CONFIG_ARCH option completely as every stage can have any architecture of its own. Thus, almost all the components of coreboot are identified as being part of one of the three stages (bootblock, romstage or ramstage). The components which cannot be classified as such e.g. smm, rmodules can have their own compiler toolset which is for now set to *_i386. Hence, all special classes are treated in a similar way and the compiler toolset is defined using create_class_compiler defined in Makefile. In order to meet these requirements, changes have been made to CC, LD, OBJCOPY and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others. Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the toolsets are defined using create_class_compiler. Few additional macros have been introduced to identify the class to be used at various points, e.g.: CC_$(class) derives the $(class) part from the name of the stage being compiled. We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER as they do not make any sense for coreboot as a whole. All these attributes are associated with each of the stages.

Start using the rmodtool for generating rmodules. rmodule_link() has been changed to create 2 rules: one for the passed in <name>, the other for creating <name>.rmod which is an ELF file in the format of an rmodule. Since the header is not compiled and linked together with an rmodule there needs to be a way of marking which symbol is the entry point. __rmodule_entry is the symbol used for knowing the entry point. There was a little churn in SMM modules to ensure an rmodule entry point symbol takes a single argument.

There are 2 methods currently available in coreboot to load ramstage from romstage: cbfs and vboot. The vboot path had to be explicitly enabled and code needed to be added to each chipset to support both. Additionally, many of the paths were duplicated between the two. An additional complication is the presence of having a relocatable ramstage which creates another path with duplication. To rectify this situation provide a common API through the use of a callback to load the ramstage. The rest of the existing logic to handle all the various cases is put in a common place.

Because pointers can be 32bit or 64bit big, using them in the coreboot table requires the OS and the firmware to operate in the same mode which is not always the case. Hence, use 64bit for all pointers stored in the coreboot table. Guess we'll have to fix this up once we port to the first 128bit machines.

The TPM code wasn't previously honoring MOCK_TPM=1. Because of this, boards with TPMs that didn't handle S3 resume properly would cause a hard reset. Allow one to build with MOCK_TPM=1 on the command line so that S3 can still work.

2013-03-29chromeos: remove CACHE_ROM automatic selectionAaron Durbin
It's not appropriate for the chromeos Kconfig to automatically select CACHE_ROM. The reason is that enabling CACHE_ROM is dependent on the board and chipset atrributes.

2013-03-23vboot module: fix compilation issuesAaron Durbin
There were 3 things stopping the vboot module from being compiled: 1. The vboot_reference code removed in the firmware/arch/$(ARCH)/include directory. This caused romcc to fail because romcc fails if -I<dir> points to non-existent directory. 2. The rmodule API does not have the no-clearing-of-bss variant of the load function. 3. cbfs API changes.

coreboot tables are, unlike general system tables, a platform independent concept. Hence, use the same code for coreboot table generation on all platforms. lib/coreboot_tables.c is based on the x86 version of the file, because some important fixes were missed on the ARMv7 version lately.

2013-03-22vboot: pass correct coreboot include pathsAaron Durbin
The coreboot include were not being passed correctly when building vboot_reference. The paths being included were of the src/<dir> form. However, vboot_reference lives in src/../vboot_reference. That coupled with the recursive make call made vboot_reference not see coreboot's header files. Fix this by appending ../ to coreboot's default include paths.

2013-03-22romstage: add support for vboot firmware selectionAaron Durbin
This patch implements support for vboot firmware selection. The vboot support is comprised of the following pieces: 1. vboot_loader.c - this file contains the entry point, vboot_verify_firmware(), for romstage to call in order to perform vboot selection. The loader sets up all the data for the wrapper to use. 2. vboot_wrapper.c - this file contains the implementation calling the vboot API. It calls VbInit() and VbSelectFirmware() with the data supplied by the loader. The vboot wrapper is compiled and linked as an rmodule and placed in cbfs as 'fallback/vboot'. It's loaded into memory and relocated just like the way ramstage would be. After being loaded the loader calls into wrapper. When the wrapper sees that a given piece of firmware has been selected it parses firmware component information for a predetermined number of components. Vboot result information is passed to downstream users by way of the vboot_handoff structure. This structure lives in cbmem and contains the shared data, selected firmware, VbInitParams, and parsed firwmare components. During ramstage there are only 2 changes: 1. Copy the shared vboot data from vboot_handoff to the chromeos acpi table. 2. If a firmware selection was made in romstage the boot loader component is used for the payload. Noteable Information: - no vboot path for S3. - assumes that all RW firmware contains a book keeping header for the components that comprise the signed firmware area. - As sanity check there is a limit to the number of firmware components contained in a signed firmware area. That's so that an errant value doesn't cause the size calculation to erroneously read memory it shouldn't. - RO normal path isn't supported. It's assumed that firmware will always load the verified RW on all boots but recovery. - If vboot requests memory to be cleared it is assumed that the boot loader will take care of that by looking at the out flags in VbInitParams. Built and booted. Noted firmware select worked on an image with RW firmware support. Also checked that recovery mode worked as well by choosing the RO path.

These were not separable or it would have been two CLs. Enable CHROMEOS configure option on snow. Write gpio support code for the mainboard. Right now the GPIO just returns hard-wired values for "virtual" GPIOs. Add a chromeos.c file for snow, needed to build. This is tested and creates gpio table entries that our hardware can use. Lots still missing but we can now start to fill in the blanks, since we have enabled CHROMEOS for this board. We are getting further into the process of actually booting a real kernel.
