Linux-2.4.31 porting

I have used 2.4.24 running on an mpc8247 based board.  My board uses SMC1,
SCC3 and SCC4 for tty,
(console on SCC4) so I had to edit the configuration in uart.c, but no other
changes.  You probably have
a configuration mis-match, maybe your parallel port pins are not getting set
up right.

By the way, 2.4.24 put FCC ethernet tables in reserved memory, but I think
that was fixed by 2.4.31.
Check that you have CONFIG_8272 in your .config file to be sure.

Also, I worked from CONFIG_ADS8260 and I couldn't make a bit of sense of the
PCI implementation.
I think the mpc8266ads_pci.c implementation assumes some setup from the
bootloader. I'll be glad to share
what I did (though I'm not very sure of it) if you run into the same
problem.
