QEMU Malta
==========
Big-endian mode
---------------
QEMU run string::
qemu-system-mips -nodefaults -M malta -m 256 \

gxemul -Q -x -e maltabe -M 256 0xbfc00000:barebox-flash-image
Little-endian mode
------------------
Running little-endian Malta is a bit tricky.
In little-endian mode the 32bit words in the boot flash image are swapped,
a neat trick which allows bi-endian firmware.
You have to swap words of ``zbarebox.bin`` image, e.g.::
echo arch/mips/pbl/zbarebox.bin \
| cpio --create \
| cpio --extract --swap --unconditional
QEMU run string::
qemu-system-mipsel -nodefaults -M malta -m 256 \
-nographic -serial stdio -monitor null \
-bios barebox-flash-image
