This is the base files of the Nios2 port. Almost everything is comming from u-boot.
When those files are acked, I'll post drivers and utility commands. 

The port include a generic board. The board configuration file nios_sopc.h is
generated using sopc-create-header-file (Altera utility). Then, names in this
file are converted to generic names in config.h.

Soo many patches ;). You can safely combine all these into two
patches, one for the nios2 support and one for the generic board.
The patches are only useful as a whole anyway, so no need to split
them up that fine. You will hit the list limit, so give me some time
to go to the moderator interface and and it through.

I'm not through all patches, but some remarks here:

There is some whitespace damage all around like spaces which should be
tabs. Also, please do not use direct pointer derefs to access registers.
You should use readl/writel accessors for them.

Thanks for doing this work. Although I don't have a nios baord, I really
appreciate extending barebox to more architectures.

Sascha

Is that a "Linux rule" ? Is there other ones ? (I always convert tabs to
whitespaces....).

Okay I will.

Barebox is so much better than Uboot, you guys did a really good job.
Barebox
even helped my to understand some Linux concepts.

Hi Sasha,

I didn't how to split the patches so I splitted everything :) I'll fight
with git to revert my commits and do it again...

This port is working but it's going to be a long process including it in
barebox git because I don't have a lot of time
(my baby boy needs my time) and I'm not a git master at all, I'm just an
hardware guy playing with the kernel (why the
hell it is so complicated ? I think it is kind of a filter/test for
patchers. If you can't use git you can't send patches ;)).

Souldn't be less complicated if I had a separate branch to work on it ?

See Documentation/CodingStyle in the Linux kernel source tree.

It's always safe bet to divert the decent U-Boot bits to an initial port
(and a new architecture support) of Barebox, but at the same time it's a
good opportunity to rebase old stuff against the recent Linux kernel.

For instance, if some of nios2 asm header files can be adjusted to recent
ones, I'd recommend to do it this time.  It won't take so long, and helps
you avoid sending small patches later :-)
