Karthikeyan Ramasubramanian 4763a5a470 soc/amd/mendocino: Increase CBFS_MCACHE size 
CBFS_MCACHE is currently experiencing overflow with CBFS verification
enabled. Reduce the pre-x86 cbmem console size from ~5.5 KiB to 4 KiB.
This reduction along with the available free space in PSP shared buffer
(32 KiB) helps to increase the CBFS_MCACHE size from 8 KiB to required
14 KiB.

BUG=b:259342909
TEST=Build and boot to OS in Skyrim. Ensure that there are no CBFS
mcache overflows.
FMAP: area COREBOOT found @ 80a000 (8347648 bytes)
VB2:vb2_digest_init() 0 bytes, hash algo 2, HW acceleration unsupported
CBFS: mcache @0x00019a40 built for 67 files, used 0x19a0 of 0x1c00 bytes
CBFS: Found 'apu/amdfw_a' @0x0 size 0x3ff80 in mcache @0x0001b640
VB2:vb2_digest_init() 262016 bytes, hash algo 2, HW acceleration enabled
Ensure that firmware_CbfsMcache FAFT test is successful.

coreboot README

coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.

With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.

coreboot was formerly known as LinuxBIOS.

Payloads

After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.

See https://www.coreboot.org/Payloads for a list of supported payloads.

Supported Hardware

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

Build Requirements

  • make
  • gcc / g++ Because Linux distribution compilers tend to use lots of patches. coreboot does lots of "unusual" things in its build system, some of which break due to those patches, sometimes by gcc aborting, sometimes - and that's worse - by generating broken object code. Two options: use our toolchain (eg. make crosstools-i386) or enable the ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this case).
  • iasl (for targets with ACPI support)
  • pkg-config
  • libssl-dev (openssl)

Optional:

  • gdb (for better debugging facilities on some targets)
  • ncurses (for make menuconfig and make nconfig)
  • flex and bison (for regenerating parsers)

Building coreboot

Please consult https://www.coreboot.org/Build_HOWTO for details.

Testing coreboot Without Modifying Your Hardware

If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.

Please see https://www.coreboot.org/QEMU for details.

Website and Mailing List

Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
