We can use that option and drop the file from this patch. However in that case I will have to reintroduce it and remove the config option in a subsequent patch.

Sure, we can do it if you prefer that. In my opinion it is much cleaner to introduce a new config file, instead of adding random ifdef statements into another file. -Gabor

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.
