Ben,
This line item has finally come around on the guitar!
And I have a question for you...
How come this additional clear_bats call isn't seen
as a generic fix? It is possible that the bootloader
has left some crufty (high) BATs hanging around.
Or are you suggesting just adding something like:
li r10, 0
mtspr SPRN_DBATxU,r10
mtspr SPRN_DBATxL,r10
for x in (4 .. 7) to the tail end of load_up_mmu as
the general fix?
Thanks,
jdl
