MIPS: qemu-malta: add support for emulated MIPS Malta board
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>
