Hi list,
while working on fdt support for the nios2 I was reading some code for
other archs I also looked at the microblaze code and I believe I found
some leftovers from a copy/paste action, attached is a small patch
(untested) to fix a debug print and (more important) remove a useless
call to early_init_dt_check_for_initrd.
I do still have one concern, do I understand correctly that there is no
way to do address-translation (the "ranges" stuff) on a flattenend tree,
using the of_get_flat_dt_* functions? This would mean that this code
would fail to get the correct address for a uartlite connected to a bus
that has address-translation.
Greetingz
Walter
