On some platforms with SPI flashes larger than 32MB, the SPI flash may power up in 4-byte addressing mode and this command needs to be sent before coreboot's 3-byte address commands can be interpreted correctly. On flashes that don't support 4-byte addressing mode or where it is already disabled, this command should be a no-op. config SPI_FLASH_FORCE_4_BYTE_ADDR_MODE bool default n help This will force coreboot to send addresses as 4-bytes instead of 3-bytes. On some platforms with SPI flashes larger than 16MB, the SPI flash may need to remain in 4-byte addressing mode. endif # SPI_FLASH config HAVE_EM100PRO_SPI_CONSOLE_SUPPORT def_bool n
