Push selection of lowlevel_init functions out to the individual
boards.
Pushing it to the individual boards allows us on a per board basis
to migrate to a design where the mach-at91 code no longer
calls the board specific code.
When the dependency mach-at91 => boards is dropped for
a board the migration to a multi-image setup is one step closer.

it was easy to see that at91sam9x5_lowlevel_init.c was no
longer used.
Delete the file and the now unused CONFIG symbol and it uses

Create a new file at91sam926x_board_init.h which
is a copy of at91sam926x_lowlevel_init.c with a few minor
adjustments:
- We no longer call board code from this function
- The struct is renamed to avoid name clashes
- the function is rename to better match the prurpose
This file will be used in subsequent transformations
Otherwise just added the reset vector to the board code
and drop the now obsolete CONFIG selectst

All at91sam9261 based boards uses board specific
reset vectors so the mach-at91 provided version is
no longer in use.
Delete unused CONFIG symbols too.

the previous lowlevel_init.c was replaced with a simple
lowlevel.c with contains only the reset vector.

For all Calao USB boards move reset vector to board code.
Introduce two different lowlevel.c files, on
for each processor.
Include a rename to make filenames similar.

Just to let you know the current status here: While I think you are on
the right track with this, I'm currently lacking the bandwidth to
properly review this series. I'm a bit hesitant to just throw it into
-next without any kind of review, so I'm still hoping for others to take
a look.
Regards,
Lucas

Thanks for the heads-up.
Review is a must as I am in unknown land here.
The most important part is if the apporach is correct or not.
I have continued with the effort to DT enable
the at91sam9263ek board and have a barebox that
boots using DT now with most stuff working.
atmel_lcdfb did not support DT which I have added.
All other drivers worked more or less out-of-the-box.
In the process there have been a few cleanups and fixes
and I will post the patches after some more testing.
Not everything is working yet:
- the NAND cannot read BBT (NAND is properly identified)
- environment load /dev/env0 fails (maybe related to the above)
- no kernel booted yet
- bootstrap not tested (will provide a defconfig if I get it working)
- network is not yet tested
I expect to work on the above list and hold back patches
until everything is working. That will take a few days.
If everything goes like for the other challenges I will
run to the other side of the forest to pick up a small
splinter of wood in my effort to find a fix.
Which is OK as this is part of the fun :-)
Sam
