Hi Marek,
taihu was my next target to test, so thanks for sparing my time. Next
would be to try to dig up a target called Walnut. Check this:
http://lists.denx.de/pipermail/u-boot/2008-November/043400.html

I cannot see that QEMU lists walnut as a target. Maybe the patches wasn't sent?

Best regards,
Frank
