Remove address from GPLv2 headers 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>

Add predefined __ROMSTAGE__ and __RAMSTAGE__ macros This patch adds the macros __ROMSTAGE__ and __RAMSTAGE__ which get predefined in their respective stages by make, so that we have one specific macro for every stage. It also renames __BOOT_BLOCK__ and __VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency. This change is intended to provide finer control and clearer communication of intent after we added a new (optional) stage that falls under __PRE_RAM__, and will hopefully provide some robustness for the future (we don't want to end up always checking for romstage with #if defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) && !defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The __PRE_RAM__ macro stays as it is since many features do in fact need to differentiate on whether RAM is available. (Some also depend on whether RAM is available at the end of a stage, in which case #if !defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be authoritative.) It's unfeasable to change all existing occurences of __PRE_RAM__ that would be better described with __ROMSTAGE__, so this patch only demonstratively changes a few obvious ones in core code. BUG=None TEST=None (tested together with dependent patch).

Introduce stage-specific architecture for coreboot 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.

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.

# Common recipes for all stages
###########################################################################
New mechanism to define SRAM/memory map with automatic bounds checking This patch creates a new mechanism to define the static memory layout (primarily in SRAM) for a given board, superseding the brittle mass of Kconfigs that we were using before. The core part is a memlayout.ld file in the mainboard directory (although boards are expected to just include the SoC default in most cases), which is the primary linker script for all stages (though not rmodules for now). It uses preprocessor macros from <memlayout.h> to form a different valid linker script for all stages while looking like a declarative, boilerplate-free map of memory addresses to the programmer. Linker asserts will automatically guarantee that the defined regions cannot overlap. Stages are defined with a maximum size that will be enforced by the linker. The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date. The mechanism is implemented for all boards in the ARM, ARM64 and MIPS architectures, and should be extended onto all systems using SRAM in the future. The CAR/XIP environment on x86 has very different requirements and the layout is generally not as static, so it will stay like it is and be unaffected by this patch (save for aligning some symbol names for consistency and sharing the new common ramstage linker script include). BUG=None TEST=Booted normally and in recovery mode, checked suspend/resume and the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies with ToT and looked for red flags.

CBFS: Correct ROM_SIZE for ARM boards, use CBFS_SIZE for cbfstool Some projects (like ChromeOS) put more content than described by CBFS onto their image. For top-aligned images (read: x86), this has traditionally been achieved with a CBFS_SIZE Kconfig (which denotes the area actually managed by CBFS, as opposed to ROM_SIZE) that is used to calculate the CBFS entry start offset. On bottom-aligned boards, many define a fake (smaller) ROM_SIZE for only the CBFS part, which is not consistently done and can be an issue because ROM_SIZE is expected to be a power of two. This patch changes all non-x86 boards to describe their actual (physical) ROM size via one of the BOARD_ROMSIZE_KB_xxx options as a mainboard Kconfig select (which is the correct place to declare unchangeable physical properties of the board). It also changes the cbfstool create invocation to use CBFS_SIZE as the -s parameter for those architectures, which defaults to ROM_SIZE but gets overridden for special use cases like ChromeOS. This has the advantage that cbfstool has a consistent idea of where the area it is responsible for ends, which offers better bounds-checking and is needed for a subsequent fix. Also change the FMAP offset to default to right behind the (now consistently known) CBFS region for non-x86 boards, which has emerged as a de-facto standard on those architectures and allows us to reduce the amount of custom configuration. In the future, the nightmare that is ChromeOS's image build system could be redesigned to enforce this automatically, and also confirm that it doesn't overwrite any space used by CBFS (which is now consistently defined as the file size of coreboot.rom on non-x86).
