[U-Boot-Users] problem with cfi_flash.c & AT91RM9200DK

[Morten]

Hello !

I have exchanged the flash on my AT91RM9200DK with a AT49BV320C cfi flash,
and done all needed mods to the config file, every thing seems ok except 
that it get the size of the flash
incorectly.

It sayes that it is a 16x16 4m, 71 sector cfi complient flash, when it 
should be a 2097 x 16, 32m, 71 sector flash ?

Anyone have any tips for me on how to fix this ? protect / unprotect seems 
to work fine, and it even writes without
complaining, but nothing actualy gets writen !
