Honesty is the best policy.

I have no real malta board, but I have qemu-malta pseudo-board.
I can test barebox on the emulator, but I can't give a warranty that
barebox will work on real malta board.

The MIPS Malta is a reconfigurable device
(http://www.linux-mips.org/wiki/Mips_Malta).
It can be used with very different core cards.

So, I have separated qemu-malta barebox board directory, and nobody
can imagine to run it on real malta board.
But if I have malta barebox board directory, anybody can be misled.
