[PATCH 0/2] powerpc: dts: p2020: Allow to use P2020 DTS files from Linux

[Pali Rohár]

This patch series imports device tree include files for comaptibility
with P2020 device tree files from upstream Linux kernel. So it allows to
share same P2020 board device tree files between Linux kernel and U-Boot.

Pali Rohár (2):
  powerpc: dts: p2020: Add fsl/p2020si-pre.dtsi and
    fsl/p2020si-post.dtsi symlinks
  powerpc: dts: p2020: Add serial0 and serial1 via pq3-duart-0.dtsi

[PATCH 1/2] powerpc: dts: p2020: Add fsl/p2020si-pre.dtsi and fsl/p2020si-post.dtsi symlinks

[Pali Rohár]

P2020 DTS files in upstream Linux kernel use fsl/p2020si-pre.dtsi and
fsl/p2020si-post.dtsi include device tree files.

Add symlinks for these include device tree files into U-Boot powerpc
directory and points them to U-Boot inline device tree files p2020.dtsi and
p2020-post.dtsi.

This allows to use P2020 DTS files from upstream Linux kernel in U-Boot.

[PATCH 2/2] powerpc: dts: p2020: Add serial0 and serial1 via pq3-duart-0.dtsi

[Pali Rohár]

Import pq3-duart-0.dtsi device tree include file from upstream Linux kernel
for P2020. This allows U-Boot to use P2020 device tree files from upstream
Linux kernel which reference serial0 or serial1 devices.
