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

[IHOLLO]

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.

Did you turn on New PCI bus code(CONFIG_PCI_NEW)?

ADM5120: MIPS-I or MIPS32? WAS(Re: ADM5120: linux-2.4.31-adm.diff.bz2 does not support PCI bus?)

[IHOLLO]

Thanks Yoichi, that is exactly what you suggested, turn on New PCI bus 
code(CONFIG_PCI_NEW) then the kernel can be compiled  now.

Here is another question: What CPU type should I choose to compile 
applications for ADM5120? the spec says it is MIPS32, but I can not run 
MIPS32 applications on my board while MIPS-I executable works just fine.

#file busybox (works fine. compiled as mips-I)
busybox: ELF 32-bit LSB MIPS-I executable, MIPS, version 1 (SYSV), 
dynamically linked (uses shared libs), stripped

#file busybox (can not execute this program. compiled as mips32)
busybox: ELF 32-bit LSB executable, MIPS, version 1 (SYSV), dynamically 
linked (uses shared libs), stripped
