This series adds an initial support for Rockchip SoCs and has been
tested on a Radxa Rock board, on which I'm able to load a kernel from
the network and boot it [1].
At the moment Barebox must be chainloaded from the Rockchip binary
bootloader which performs low-level initializations and loads Barebox
from the "boot" partition on the NAND.
Barebox should be written using the same procedure used for kernels:
it must be prepared with the mkimage tool and then written with
rkflashkit.
There is a u-boot code released by Rockchip [2] which probably
includes all the low-level initializations but I'm not brave enough to
try it.
The patchset adds ethernet and pinctrl drivers, PLL and clocks
initialization, and code to power on the external PHY of the board
through the PMIC.

This patch adds support for the Synopsys 10/100 Mbps Ethernet MAC used
on some ARC devices and on Rockchip SoCs.

lower 16 bits.

Awesome! I'm happy to see barebox support for one of the more popular
Linux ARM architectures.
The patches look quite good and there's not much to be done to
make them ready for merging.
I'm just on the way to merge the Linux devicetree files into barebox
and use them where possible so we do not duplicate the devicetrees in
barebox. Could you post a followup once to base the rockchip dts files
on the Linux dts files once I have everything in place? I saw that you
already use the mainline dts files, but these do not contain the
ethernet nodes for example.
Also I'd like to let rockchip use the multi image mechanism. This is not
much work when you know what to do. You could change it yourself or I do
the change for you, but in this case, could you give the result a test?
Sascha

Ok, I will do. Just a question: my series is against -next because it
requires commit 6720ad6f16db5839a72aa8b53e89918a4f0059bd "clk: move
of_clk_get_parent_name() to common clk code", while your dts branch
derives from master and doesn't have this commit. Which branch should
I base the next version on?

I'm not familiar with multi-image support but I would be glad to try
it if you're willing to implement it.

I reshuffled the patches in -next so that your patches have the correct
dependencies.

Ok, I pushed everything to -next. The multi image conversion is in the
attached patch (also included in -next). Try building rockchip_defconfig
and start images/barebox-radxa-rock.img. If it works then we are lucky,
if not we'll have to work out a way to debug the patch.
BTW I noticed the upstream radxa rock dts file does not have a board
specific compatible. I added this in my patch, but this should be done
upstream.

Subject: [PATCH] ARM: Rockchip: switch to multiimage support
- Add images/Makefile.rockchip
- Allow multiple boards to be selected
- protect initcalls with appropriate of_machine_is_compatible
- rename board specific config to SoC config
- Add dtb file to compilation
- turn barebox_arm_reset_vectorto ENTRY_FUNCTION
- pass dtb to barebox_arm_entry

The image works. There is only a small change (below) to do in board
file to postpone the call of hostname_init() until the dt root node is
set, otherwise the check on board compatible always returns false.

Hi Beniamino,
very cool that you're working on getting a better boot loader for us :-)

Until now I didn't give it much thought, but according to usage-model.txt the
board-specific compatible is a required property. So we'll need to add it to
the board dts in the kernel too.
So you could send a patch, or I'll prepare one in the next days.
