That's perfectly O.K. for me.

Unfortunatelly, at the time I submitted my patch, toolchain and u-boot
were only available for download from xilinx or avnet.

The toolchain (tgz archive, binary) is available at:

|git://git.xilinx.com/xldk/microblaze_v1.0_le.git|

Some more information can be found in the Xilinx Wiki:
http://xilinx.wikidot.com/microblaze-linux-le

I tried to build u-boot, but did not succeed, mostly because of lack of
time.

There are patches for gcc available in the internet, maybe someone can
try to build the toolchain using them. It would be a great benefit being
able to build a mmu-less toolchain for small systems. Unfortunatelly, I
don't have much time for this in the next few months.

That is also true for the qemu-config. I believe it is only a few lines
in some config file away, but I am not experienced with qemu. Someone
who knows qemu and device trees may manage it quickly.

Of course.

Kind regards
