That reminds me that I need to make the spi driver
available somewhere all the time. But I am not sure
when I will be able to do that. Meanwhile, you should
be able to start of with the old driver for the 8xx
that should be around somewhere under the rubble. :-)
Or, you can start off with the sample code in u-boot
that was derived from the original driver.

I just wanted to add, that if anyone is going to get busy again with the 8xx 
SPI driver(s) in u-boot and linux-2.4, I'd like to know, since I am too.
In u-boot there are two 8xx-SPI-drivers, one software and one in hardware, and 
they seem both broken now (I'm still using CVS versions around 1.1.2 
somewhere maybe I should cvs update :-)
Specifically spi_xmit() get each other in the way. There are two such 
functions in u-boot, both non-static and with (very) different prototypes, so 
I am starting to figure out the best way of fixing that mess. Is anyone busy 
with the same task?

You have better chances  for  a  useful  reply  if  you  ask  on  the
U-Boot-Users mailing list instead.
