OK, i use kernel 2.4.4-20020321 from denx and linux-mtd (20020403),
h"re's my patches.
Sorry but i have not look at the code since a long time because i'm
working on hardware now (i've to make our own board), so i don't provide
you some explanation but you can ask me more question if you need.

1) apply "linux-2.4.4-2002-03-21-mpc8260ads-20020531.patch" to linux
code it give support for mpc8260ads to the kernel config
2) apply "mtd-20020403-edu-20020425.patch" to the mtd code. it give
support for mpc8260ads flash.
3) apply "linux-2.4.4-2002-03-21-mtd-20020403-edu-20020425.patch" to
linux code. I had to make it because mtd doesnt compile (bacward
compatibility), I don't knoww if this patch is th good way but it work
for me.
4) merge mtd code to linux code with the mtd script

compile linux (take a look at the config)

Hope this help.
