This series adds support for a generic DT based 2nd stage ARM image.
This image can be enabled in Kconfig for multiimage based ARM builds.
The result is an image which can be started just like a Kernel and just
like the Kernel it will pick the device tree from r2, so basically
a put-it-somewhere-as-a-kernel image. This can help with starting
barebox on qemu.

Sascha Hauer (8):
dtc: Update update-dtc-source.sh from Linux
scripts/dtc: Update to upstream version v1.5.0
pbl: Implement strrchr
Compile libfdt for barebox
common: return "none" when board unset
ARM: Add generic device tree 2nd stage support
ARM: i.MX: Do not hang() on unknown SoCs
ARM: i.MX: When generic DT image is enabled do not hardcode SoC
