Discussion:
Next step to enable DT support for at91sam9263ek?

Hi all.

I have now spent some time trying to dive into how to enable DT
support for at91sam9263ek - but so far with only limited success.
I have copied the device tree from the kernel and included
the tree in the build. This step was simple.

I also updated the ENTRY_FUNCTION to take a pointer to the ftd.
Also simple.

There was a few build issues that I then had to fix.
But when running the resulting barebox nothing was printed to
the console.
I ended up dropping following from the build:
arch/arm/boards/at91sam9263ek/init.c
arch/arm/mach-at91/at91sam9263.c
arch/arm/mach-at91/at91sam9263_devices.c

Thein I got following output when booting:

barebox 2017.07.0-00082-g265d9e416-dirty #27 Sat Jul 8 00:00:54 CEST 2017

Maybe you have to create the partition.

Hit any key to stop autoboot: 1

This does not look entirely correct...

Right now I am a bit stuck for what would be next step - any hints
would be highly appreciated.

The current patch looks like this (with some hacks included):

Hi Sam,
Post by Sam Ravnborg
Hi all.
I have now spent some time trying to dive into how to enable DT
support for at91sam9263ek - but so far with only limited success.
I have copied the device tree from the kernel and included
the tree in the build. This step was simple.
I also updated the ENTRY_FUNCTION to take a pointer to the ftd.
Also simple.
There was a few build issues that I then had to fix.
But when running the resulting barebox nothing was printed to
the console.

Maybe you have to create the partition.

Hit any key to stop autoboot: 1
This does not look entirely correct...
Right now I am a bit stuck for what would be next step - any hints
would be highly appreciated.
Probably a lot of the devices present on the AT91 boards have driver
with no proper DT support in Barebox, so you might need to extend some
of them.

Also if the boards have any specific board code, you need to convert
that to initcalls guarded by the board DT compatible.

HTH,
Lucas
