Chris Wang 4c4a360018 soc/amd/picasso: clean up and re-sort UPD table 
Clean up the unused UPD and re-sort the table, and also update
the new phy parameter in the soc code and overridetree.

remove:
	EDpPhySel
	EDpVersion
rename:
	DpPhyOverride -> edp_phy_override
	EDpPhySel -> edp_physel
	DpVsPemphLevel -> edp_dp_vs_pemph_level
	MarginDeemPh -> edp_margin_deemph
	Deemph6db4 -> edp_deemph_6db_4
	BoostAdj -> edp_boost_adj

eDP phy setting:
    DP_VS_LEVEL0_PREEMPH_LEVEL0 = 0x00(0.4v 0db swing 0,pre-emphasis 0)
    COMMON_MAR_DEEMPH_NOM = 0x004b
    COMMON_SELDEEMPH60 = 0x0
    CMD_BUS_GLOBAL_FOR_TX_LANE0 = 0x80

BUG=b:171269338
BRANCH=zork
TEST=Build, verify the parameter pass to picasso-fsp

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:
