Hi!


I have made small instruction to run mips barebox under qemu:

0. Change dir to barebox sources

   $ cd barebox.mips.git

1. Apply patches (already posted to barebox@lists.infradead.org)
    0001-include-linux-stat.h-make-MIPS-arch-possible.patch
    0002-Add-MIPS-arch-support-to-barebox.patch

2. Configure & build barebox.bin

   $ cp arch/mips/configs/generic_defconfig .config
   $ make oldconfig ARCH=mips
   $ make ARCH=mips CROSS_COMPILE=<your mips cross-compiler prefix>

3. Get qemu. My qemu:

   $ qemu-system-mips --version
   QEMU emulator version 0.14.0 (Debian 0.14.0+dfsg-5.1), Copyright
(c) 2003-2008 Fabrice Bellard

4. Run barebox under qemu:

   $ qemu-system-mips -M malta -m 128 -bios ./barebox.bin -nodefaults
-serial stdio -nographic

or

   $ qemu-system-mips64 -M malta -m 128 -bios ./barebox.bin
-nodefaults -serial stdio -nographic

4. Have fun!

Here is my barebox log.
