You are right with 0x87fc. It is one more point.
Also if your brg clock-frequency-property was correctly fixed from
u-boot.
My story is follow: we have mpc8247 based card.
The problem with smc happens due to the cpm reset.
Of course, if you have not CONFIG_PPC_EARLY_DEBUG_CPM with
CONFIG_PPC_CPM_NEW_BINDING.
May be it is some kind of mistake, but i could fix the problem with the
patch i told above.
Could give me some your note, please? Thank you.
Regards
Sergej.
