Add minimal support for the MIPS Malta CoreLV board emulated by Qemu. The only supported peripherial is the UART. This is enough to boot U-Boot to the command prompt both in little and big endian mode. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>
