Trying to Upstream support for Allwinner V5.

[Walker Ryan]

Hey all,

I'm trying to upstream support for the Allwinner V5 using the Lindenis V5 SBC. I hope to eventually build a completely open source stereo camera board using the SOC. Before building the hardware I want to ensure I can provide proper support for building images in Buildroot. The vendor's BSP is a really old fork of uboot and Linux (2014), I've been merging some parts from the forks.

This is what I've done so far.

1. Pulled in the sun8iw12p1-*.dts from forks. Files here.
2. Took genimage.cfg from board/olimex/a33_olinuxino/genimage.cfg
3. Several u-boot patches here,
   1. Merging in cpu_sun8i.h from the vendor fork
   2. Snubbing out functions in arch/arm/cpu/armv7/sunxi/psci.c
   3. Added the board aliased against some CONFIG_MACH_SUN50I_H6 config. As the H6 is a similar chip.
4. Took board/interruptlabs/stereo/lindenis_v5_defconfig from the vendor linux fork.

Here is the entire diff.

I've created a sdcard image, flashed it, and powered it up but nothing yet. I would really appreciate any guidance, documents or feedback on this task. Thanks!

I was working on this a few months back. I had to push pause as the complexity was above my head. It was eating up days that I couldn't justify spending.

If you're serious about helping out, I can send you a Lindenis v5; email me.
