I upgraded our kernel for our custom p2010rdb based board from 3.4 to 4.1 a=
nd I cannot get the
PCI controller to work, it is not initialized as can be seem by the below d=
mesg fro 3.4 and 4.1.
Sorry to say, PCI is not my cup of tea so I don't not know how to find the =
culprit.
I have checked what I can but nothing stands out and I would appreciate som=
e help/pointers
dmesg for 4.1:
