Preliminary IQ80321 patch available

A _very_ prelimary, early patch for the IQ80321 port is available @:

  ftp://source.mvista.com/pub/ds-patches/patch-2.4.18-rmk5-iq80321.gz

This is a bit behind the main rmk patch, but I ran into some problems 
with getting the board to work on rmk7.  As I'm leaving for vacation in 
about 5 minutes, I figure this is a better starting point then something 
that crashes for people who want to start playing with the board and 
give me some feedback. 

Quick Directions:

make iq80310_config
make oldconfig
make dep 
make zImage

In Redboot:

RedBoot> load -r -b 0x01008000 -m y

Now y-modem the zImage and when done:

go 0x01008000

The default config uses the e1000 GigE port to mount NFS.  

The only things tested so far are:

  - E1000 driver
  - RamDisk
  - MTD access to the onboard flash

The PCI code works, but is full of udelay(50) calls for the moment
until the code is cleaned up. It needs to be fixed up to match the
iq80310 port in the 2.5 tree so that it properly deals with imprecise
data aborts.

Note that the only backplane I've tested the board on is a SuperMicro
motherboard provided by Intel.  I could not get any of my boards to
boot(firmware halts) up properly on the 80303BP backplane from Cyclone 
microsystems. Note that the boards are very fidgety when it comes to
having the DIP switches configure properly for what backplane you're
on. Also, Linux may not work on certain backplanes. If you run into issues, 
please email me the following information about your backplane:

Manufacturer, model, chipset, bios version, PCI or PCI-x.

I will be out on vacation till tuesday with no email access, but
please send me (and the linux-arm-kernel list) any issues you have
and I will answer as soon as I get back. Patches for issues are also
more then welcome.

Also, a big thanks to Rory Bolt from Quantum for doing the initial
port from the iq80310 code.

Enjoy!
