It is really several years back when I have looked at it last time but I
think that toolchain is fixed for quite some time and only changes in
microblaze u-boot code are needed but really I would have to check and
start to play with it.

Thanks,
Michal

I think someone should sort this out. It would be good to remove this
code. Is there a toolchain group at Xilinx?

Xilinx has a toolchain group. I just looked a I was playing with it in
January 2015 but didn't finish that. It is still on my long todo list.
Will see when I have a time to look at it.

will see but I need to do some Linux work first. Based on grep I see
that m68k is also enabling CONFIG_NEEDS_MANUAL_RELOC.
Is m68k going to be removed soon?

m68k is still active, so no, it's not being removed and we can't drop
CONFIG_NEEDS_MANUAL_RELOC just yet.

That begs the question - how is relocation support coming along with m68k?
