Hi all,

i tried your patch, but it seems to me that there are some #defines
missing?
I try to use the source/kernel on a FADS board, an in that section there
is
"BCSR1_PCCVPP1". But i can't find this value. I tried to copy some
values from ppcboot,
but these particular are not there. Are there some special includes?

I have the actual linuxppc_2_4_devel source-tree, but i can't find these
values.

regards
	Sven
