We are actually still shipping Colibri PXA270 modules for another one
or two years I believe after which Marvell stops selling us chips.

The strange thing is that I build U-Boot master more or less daily
without any known issues currently using the regular gcc 8.2 2019.01
tool chain from ARM.

The only issue is the missing DM_MMC and/or DM_USB conversion which I
started working on a long time ago but never came around properly
debugging. I may pick that one up tomorrow again.

Cheers

Marcel
