Hi
Is it possible to configure chipselect to use UPM A and UPM B in an MPC8270 chip using the new CPM device bindings patches from Scott?
I need to pass in the 3 bits for MS (machine select to the relevant MRx register).
Best regards,
Esben Haabendal

The BRx setup should be done by the firmware if at all possible.
As long as the entry is valid, cuboot-pq2.c shouldn't change the
attributes.
