Hi Arnd.
I remember I stared at this code before, good to see it gone.
There is a bit more tidiying up you can do.
Also, I suggest to split it in two patches, it itches me to see the
driver specific part mixed up with the fb_notify removal.

From: Sam Ravnborg
The mode_valid implementation had a call to
drm_bridge_chain_mode_fixup() which would be wrong as the mode_valid is
not allowed to change anything - only to validate the mode.
As the next bridge is often/always a connector the call had no effect
anyway. So drop it.

There are no users left of drm_bridge_chain_mode_fixup() and we

There is no longer any need for the run-time patching of the ipi trap
with the removal of sun4m and sun4d. Remove the patching and drop the
ipi implementation for the two machines.
The patch includes removal of patching from pcic as this was needed to
fix the build. pcic will

With only LEON supported there is no need to run-time patch
the instructions to match ASI.
Move a few functions back to C with inline asm, now that
run-time patching is not needed.
Deleted a few functions that turns out not to be used rather
than re-implement them in C
.
- Drop some of the homegrown memory allocators and use memblocks
