Ok, I will dig into this issue next weekend.

ehm yes, there is a missing driver in barebox. Thanks for pointing this
out.

Are there any suggestions to implement "8-bit NAND Flash Interface" for
the kirkwoods 88F6180/88F619x/88F6281?

This platform is "just for fun" currently, not very useful without mtd
support. :-)

The free kirkwoods sheets are well documented, maybe I could try this.
Or port some code from linux/u-boot.

But first I will fix the kwboot issue, of course.

Ok.


Thanks.
