Legacy board files for IGEP Processor Boards used 1-bit Hamming ECC layout but
new DT uses BCH8 software layout. This breaks the backward compatibility for
people that used board files before and switch to DT and have the problem that
they can't flash the rootfs using the bootloader.
This patch sets the ECC layout to 1-bit Hamming ECC in order to maintain this
compatibility.
