ADM5120: linux-2.4.31-adm.diff.bz2 does not support PCI bus?

[IHOLLO <ihollo@tom.com>]

Hi,

I am now working on a board with ADM5120 processor and want a kernel 
newer than 2.4.18, so I tried the linux-2.4.31-adm.diff.bz2 patch 
against vanilla 2.4.31 (http://www.linux-mips.org/wiki/ADMtek#Linux_2.4) 
but failed to compile it with PCI Bus support (It compiles OK without 
CONFIG_PCI). The compile error looks like this:

......

Is PCI Bus supported by this patch? Or, is there any new kernel 
availible for ADM5120?

Thanks very much.
