This is version 3 of a patchset to enable
device tree support for AT91SAM9263EK.
The patchset is made on top of previous
patches posted that move reset code to
the board files for at91 boards.
(Which are already part of -next)
On the quest towards getting so far several drivers was
converted to support DT.
These patches went in around august.
There was also issues with mach-at91 calling code
in the board directory (dependency in the
wrong direction).
This was fixed in "at91: move reset .." which is
pending (already posted).
I have failed to get the bootstrap mode to work.
It stops somewhere - and I have not invested enough
time to figure out where and why things goes wrong.
bootstrap mode was also broken before these patches.
No JTAG debugger available to help me.
And then I have at91bootstrap that works so motivation
was not too high.
I do not think the NAND support works either.
The device tree introduces some nand-controller
stuff that is not supported by barebox (at least I assume so).
And this part I did not look further into.
Next step is to get a proprietary board up and
running (which uses NOR flash).
But I wanted this patchset out in the open first.
Thanks for feedback so far - especially from Andrey.
Sam
v2 => v3
- Squashed commit introducing support for multi image
with the commit to add DT support
- Fixed init of smc
v1 => v2
Based on feedback from Andrey (thanks!)
Patches reworked and combined as a result of this
- Included two patches that makes some general
improvements to mach-at91.
(Updated since the RFC versions sent yesterday)
- Move irq_fixup, thus allowing us to call this
from board code. This makes it possible to have
less dependencies between board code and the processor
specific files in mach-at91.
- Simplified soc setup. With this change setup.c
no longer requires that at least one of the
processor specific files are built.
- Create a minimal dts file, based on top of the
dts file supplied from the kernel.
- Utilise gpio-hog - to setup gpio for PHY.
- Simpler Makefile logic in board Makefile
It is now obvious that init.c is only used for
bootstrap
- Processor specific files in mach-at91 no longer
used when DT is enabled
- Use IS_ENABLED() when it makes code simpler

This allows at91_rtt_irq_fixup() to be used outside
of the mach-at91/ directory.
Adjust all call sites to include the at91_rtt header.
Deleting one .c file is another nice side effect of this move.

The at91 soc support inherited a complex scheme
from the kernel.
This schme did not really give any benefits, and when
starting to migrate at91sam9263ek to use DT it started
to get in the way for a proper way to do things.
Replace the former setup with a simple function
pointer that can be called from setup.c.

Add at91sam9263ek.dts to build.
Include mmc1 in at91sam9263ek.dts, as mmc1 is what the evaluation
kit uses for the SD card.
Add DT specific of_init
Adjust build to drop non-DT files from mach-at91
