please use always the struct or leave it always, but not mixing the styles.

NAK, I count this worse than before.
a) including relative path
b) cidr == fidi && ner == fidi ??; how about exid?
c) struct atmel_usart3_t has same footprint in view of USART, but
using that struct in this use case is wrong. If you fear to add
some specific struct atmel_dbgu to arch specific includes please
revert to first version with comment about the magic numbers.

Ouch, that slipped through in last review. This is copied from
at91sam9g45_matrix.h.
If at91sam9x5 matches at91sam9g45 why another include? If not please
change the source of information (and include guards some lines down).

NAK, this belongs to DBGU and not to USART. I think one of the specific

I cound BDI a really useful command, please let this one in.
Undefining the rest is ok with me. But keep in mind that you remove
commands other u-boot have, this may confuse users.

Well, you read from jffs but work with ubifs later on? Is that ok?
BTW: I do not know 'nand read.jffs2', does this subcommand exist really?

I think a v3 should make it into the tree. Please send next days cause I
plan to send the pull request end of this week at the latest.
