Broadwell however uses a mrc.bin to initialse memory which needs to be located at a fixed offset. Therefore even with a separate verstage starting after the bootblock that same binary is used meaning a jump is made from RW to the RO region and back to the RW region after the binary is done. config VBOOT select VBOOT_MUST_REQUEST_DISPLAY select VBOOT_STARTS_IN_ROMSTAGE if !BROADWELL_VBOOT_IN_BOOTBLOCK config MMCONF_BASE_ADDRESS hex default 0xf0000000 config SMM_TSEG_SIZE hex default 0x800000 config IED_REGION_SIZE hex default 0x400000 config SMM_RESERVED_SIZE hex default 0x100000 config VGA_BIOS_ID string default "8086,0406" config DCACHE_RAM_BASE hex default 0xff7c0000 config DCACHE_RAM_SIZE hex default 0x10000 help The size of the cache-as-ram region required during bootblock and/or romstage.
