indeed, I encountered follow error when boot barebox (compiled with default
cfg):
dm9000 at dm90000: Wrong databus width defined at compile time
and can't use it for tftp
I have printed out the context, found that is 32bit in the dm9000 register
(read only), but in mini2440 initialize code is 16bit.
any suggestion?
