mb/google/rambi: Drop ChromeOS support
There is an ongoing effort to deprecate VBOOT_VBNV_CMOS [1] and replace
with VBOOT_VBNV_FLASH. However, the rambi's CAR is too small for early
flash access in romstage:
/usr/local/google/home/yupingso/projects/coreboot/util/crossgcc/xgcc/bin/i386-elf-ld.bfd:
Cache as RAM area is too full
/usr/local/google/home/yupingso/projects/coreboot/util/crossgcc/xgcc/bin/i386-elf-ld.bfd:
section .car.mrc_var VMA [00000000fe008000,00000000fe00ffff] overlaps
section .car.data VMA [00000000fe000000,00000000fe008787]
make: *** [src/arch/x86/Makefile.inc:194:
coreboot-builds/GOOGLE_RAMBI/cbfs/fallback/romstage.debug] Error 1
More precisely, DCACHE_RAM_SIZE is 0x8000, and the current .car.data
size is 0x76c0. If BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is unselected,
then the _bss region will increase by 0x10c8 bytes (for global variables
such as `elog_mirror_buf` and `sfg`), so that .car.data will exceed
0x8000.
Since rambi has reached its AUE (2021-09-01), disable
MAINBOARD_HAS_CHROMEOS and VBOOT configs.
