Jonathan Zhang 4337a9acaa soc/intel/xeon_sp/cpx: configure STACK_SIZE 
Before this change, we have this problem (boot log from DeltaLake
config A server):
Jumping to boot code at 0x00040000(0x755f6000)
Stack overrun on CPU0 (address 0x7574a000 overwritten). Increase stack from current 4096 bytes
ERROR: BUG ENCOUNTERED at file 'src/lib/stack.c', line 43
Linux version 4.16.18

Configure STACK_SIZE to make it larger to fix above problem.

Now, we have this boot log:
BS: BS_PAYLOAD_LOAD exit times (exec / console): 326 / 21727 ms
Jumping to boot code at 0x00040000(0x752f2000)
CPU0: stack: 0x75746000 - 0x7574a000, lowest used address 0x7574681c, stack used: 14308 bytes
Linux version 4.16.18

TESTED=booted YV3 config A to target OS.

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:

  • doxygen (for generating/viewing documentation)
  • 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:
