2015-12-30x86 chipsets: Link non-code flow CHIPSET_BOOTBLOCK_INCLUDE filesAlexandru Gagniuc
Non-code flow assembly stubs do not have to be included in bootblock.S, now that we have more freedom in bootblock linking. Rather than bringing these stubs to the config system, just link them in the bootblock. Note that we cannot fully remove CHIPSET_BOOTBLOCK_INCLUDE at this point, as some intel SOCs use this stub for code flow. objdump -h build/cbfs/fallback/bootblock.debug on a few random boards confirms that the appropriate sections are still included in the final binary.

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-10-07x86/bootblock: Use LDFLAGS_bootblock to enable garbage collectionAlexandru Gagniuc
The x86 bootblock linking is a mess. The bootblock is treated in a very special manner, and never received the update to link-time garbage collection. On newer x86 platforms, the boot media is no longer memory-mapped. That means we need to do a lot more setup in the bootblock. ROMCC is unsuitable for this task, and walkcbfs only works on memory-mapped CBFS. We need to revise the x86 bootflow for this new case. The approach this patch series takes is to perform CAR setup in the bootblock, and load the following stage (either romstage or verstage) from the boot media. This approach is not new, but has been done on our ARM ports for years. Since we will be adding .c files to the bootblock, it is prudent to use link-time garbage collection. This is also consistent to how we do things on other architectures. Unification FTW!

2015-09-09x86: bootblock: remove linking and program flow from build systemAaron Durbin
The build system was previously determining the flow and linking scripts bootblock code by the order of files added to the bootblock_inc bootblock-y variables.Those files were then concatenated together and built by a myriad of make rules. Now bootblock.S and bootblock.ld is added so that bootblock can be built and linked using the default build rules. CHIPSET_BOOTBLOCK_INCLUDE is introduced in order to allow the chipset code to place include files in the path of the bootblock program -- a replacement for the chipset_bootblock_inc make variable. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built vortex, rambi, and some asus boards.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

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.

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.
