Module support for 8260 in 2.4(.1) kernel

[Oliver Brown]

I am working on loadable driver modules for the 8260. I had to make the
changes below to the ppc_ksyms.c file to export the symbols in needed.

The problems I am having are
1. The udelay marco is not exportable. Is there a substitute? For now I
am using __delay() which is not a constant delay.
2. The m8260_cpm_hostalloc() and m8260_cpm_dpalloc do not have deallocs.
I can load my module, but I can't unload it.

I've added an init_module and cleanup_module to the fcc_enet.c from
(bitkeeper 2.5 tree). Also, I had to replace all of the udelay()'s with
__delay()'s. And I've diabled the MDIO PHY support.

Any comments or suggestions would be appreciated.

Regards,
Oliver Brown
