config EARLY_RESERVED_DRAM_BASE
hex
default 0x2000000
help
This variable defines the base address of the DRAM which is reserved
for usage by coreboot in early stages (i.e. before ramstage is up).
This memory gets reserved in BIOS tables to ensure that the OS does
not use it, thus preventing corruption of OS memory in case of S3
resume.
config EARLYRAM_BSP_STACK_SIZE

config PSP_APOB_DRAM_ADDRESS

help
Location in DRAM where the PSP will copy the AGESA PSP Output
Block.

help
Increase this value if preram cbmem console is getting truncated
config BOOTBLOCK_ADDR
hex

help
Sets the address in DRAM where bootblock should be loaded.
config C_ENV_BOOTBLOCK_SIZE
hex

help
Sets the size of the bootblock stage that should be loaded in DRAM.
This variable controls the DRAM allocation size in linker script
for bootblock stage.
config X86_RESET_VECTOR
hex

default 0x203fff0
help
Sets the reset vector within bootblock where x86 starts execution.
Reset vector is supposed to live at offset -0x10 from end of
bootblock i.e. BOOTBLOCK_ADDR + C_ENV_BOOTBLOCK_SIZE - 0x10.

help
Sets the size of DRAM allocation for romstage in linker script.
config FSP_M_ADDR

help
Sets the address in DRAM where FSP-M should be loaded. cbfstool
performs relocation of FSP-M to this address.
