Gabor Juhos - Feb. 2, 2013, 4:05 p.m.
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.

Changes since v1:
 - remove custom u-boot.lds file
 - rebased against mips/testing

can't we use CONFIG_SKIP_LOWLEVEL_INIT and drop this file?
We neither need to initialize a memory controller nor caches on Qemu.

we should extend qemu-mips.h and define CONFIG_QEMU_MALTA
respectively CONFIG_QEMU_MALTA in boards.cfg to avoid redundant code.
All differences could be handled with these options.

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.
The lowlevel_init will be used to initialize the Galileo system controller.

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.
