help
This will send an Exit 4-Byte Address Mode (E9h) command before the first
access to the SPI flash. 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.
