I have managed to get u-boot running on a couple of custom niosII boards so far, and is was not too hard.

You will need to add/modify:

MAKEALL,

Makefile,

board/mycompany/myboard/myboard.c

board/mycompany/myboard/config.mk

include/configs/myboard.h ;main config settings

If you look at the existing files, most things will be obvious.

u-boot needs one hw timer, which can also be used by your app.

The exception address in the config file must agree with sopc builder.
