bool "Expert mode"
help
This allows you to select certain advanced configuration options.
Warning: Only enable this option if you really know what you are
doing! You have been warned!
config LOCALVERSION
string "Local version string"
help
Append an extra string to the end of the coreboot version.
This can be useful if, for instance, you want to append the
respective board's hostname or some other identifying string to
the coreboot version number, so that you can easily distinguish
boot logs of different boards from each other.

help
Select the prefix to all files put into the image. It's "fallback"
by default, "normal" is a common alternative.
Provide a common CBFS wrapper for SPI storage Coreboot has all necessary infrastructure to use the proper SPI flash interface in bootblock for CBFS. This patch creates a common CBFS wrapper which can be enabled on different platforms as required. COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the common CBFS interface and prevents default inclusion of all SPI chip drivers, only explicitly configured ones will be included when the new feature is enabled. Since the wrapper uses the same driver at all stages, enabling the new feature will also make it necessary to include the SPI chip drivers in bootblock and romstage images. init_default_cbfs_media() can now be common for different platforms, and as such is defined in the library. BUG=none TEST=manual . with this change and the rest of the patches coreboot on AP148 comes up all the way to attempting to boot the payload (reading earlier stages from the SPI flash along the way).

help
Many toolchains break when building coreboot since it uses quite
unusual linker features. Unless developers explicitely request it,
we'll have to assume that they use their distro compiler by mistake.
Make sure that using patched compilers is a conscious decision.
config CCACHE

Enable this option if coreboot shall read options from the "CMOS"
NVRAM instead of using hard-coded values.
config COMPRESS_RAMSTAGE
bool "Compress ramstage with LZMA"
default y
help
Compress ramstage to save memory in the flash image. Note
that decompression might slow down booting if the boot flash
is connected through a slow link (i.e. SPI).
config INCLUDE_CONFIG_FILE
bool "Include the coreboot .config file into the ROM image"
default y
help
Include the .config file that was used to compile coreboot
in the (CBFS) ROM image. This is useful if you want to know which
options were used to build a specific coreboot.rom image.
Saying Y here will increase the image size by 2-3KB.
You can use the following command to easily list the options:
grep -a CONFIG_ coreboot.rom
Alternatively, you can also use cbfstool to print the image
contents (including the raw 'config' item we're looking for).
Example:
$ cbfstool coreboot.rom print

This draws in the blobs repository, which contains binary files that
might be required for some chipsets or boards.
This flag ensures that a "Free" option remains available for users.
config COVERAGE

help
Add code coverage support for coreboot. This will store code
coverage information in CBMEM for extraction from user space.
If unsure, say N.
config RELOCATABLE_MODULES

help
If RELOCATABLE_MODULES is selected then support is enabled for
building relocatable modules in the RAM stage. Those modules can be
loaded anywhere and all the relocations are handled automatically.
config RELOCATABLE_RAMSTAGE
depends on (RELOCATABLE_MODULES && EARLY_CBMEM_INIT)
bool "Build the ramstage to be relocatable in 32-bit address space."
default n
help
The reloctable ramstage support allows for the ramstage to be built
as a relocatable module. The stage loader can identify a place
out of the OS way so that copying memory is unnecessary during an S3
wake. When selecting this option the romstage is responsible for
determing a stack location to use for loading the ramstage.

drivers: Add I2C TPM driver to coreboot On ARM platforms the TPM is not attached through LPC but through I2C.

I assume from the code in the TPM driver that the TPM spec defines different types of delays and timeouts which each have a particular duration, and that the TPM can tell you how long each type is if you ask it. There was a large table, some members of a data structure, and a function or two which managed the timeouts and figured their value for different operations. The timeout values for the various "ordinals" were never set in the vendor specific data structure, however, and always defaulted to 2 minutes. Similarly the timeouts a, b, c, and d were never overridden from their defaults. This change gets rid of all the timeout management code and makes the "ordinal" timeout 2 minutes and the a, b, c, and d timeouts 2 seconds, the larger of the two default values.

ARM: Generalize armv7 as arm. There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

The tegra124 bootblock will ultimately need to be ARMv4, but until we have some ARMv4 code to switch over to we can leave it set to ARMv7.

Enable or disable the power button in Kconfig Some mainboards need to disable the power button to avoid turning off right after being turned on, while other boards ship with a jumper over the power button and should allow the user to configure the behavior. This adds infrastructure in the form of four mutually exclusive options which can be selected in a mainboard Kconfig (power button forced on/off, and user-controllable with default on/off) and one result bool which source code can test. (Enable the button or not.) The options have been implemented in CS5536 code and for all mainboards which select SOUTHBRIDGE_AMD_CS5536, but should be used also by other chipsets where applicable. Note that if chipset code uses the result bool ENABLE_POWER_BUTTON, then every board using that chipset must select one out of the four control options in order to build. All touched boards should have unchanged behavior, except pcengines/alix1c, traverse/geos and lippert/hurricane-lx where the power button can now be configured by the user. Build tested for alix1c, alix2d, hurricane-lx and wyse-s50. Confirmed to work as advertised on alix1c both with button enabled and disabled. Includes additional traverse/geos changes from Nathan and lippert/hurricane-lx changes from Jens to correctly use the new feature on those boards.

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.
