Subject: [PATCH] NOT YET READY TO MERGE

Changes required for Anbernic RG-ARC S and RG-ARC D. eMMC and touch
still need to be tested on the RG-ARC D.

Start with making your "flashable" image. I use 2GB and work from there. fallocate can work too, but some filesystems may not support it.

dd if=/dev/zero of=disk.img bs=1M count=2048

Create your partitions on the disk. I use fdisk and generate a gpt partition table. Note that I leave a slight offset (16MB) for U-Boot and the Rockchip loader stuff, but in my case I will be using U-Boot from the internal SPI and the storage space is entirely optional.

fdisk disk.img

I create my first partition at offset 32768 (16MB exactly) and have it end at 294911 (128MB + 16MB). This gives my boot partition 128MB to work with and ensures that my root partition starts at sector 294912. When working with 512 byte blocks (which we almost always are) it's important to ensure your starting block numbers are always divisible by 8 so that they are 4k aligned.

Subject: [PATCH 0/4] Elida KD35T133 Panel Improvements

Fix a few bugs and clean up no longer needed code on the Elida KD35T133
DSI panel, as used in devices such as the Odroid Go Advance and the
Anbernic RG351M.

[PATCH 1/2] board: rockchip: Make panel auto detect error non fatal

Make the inability to detect a panel using the auto detection code not
fail the entire boot process. This means that if the panel ID cannot
be read we don't set an environment variable for the panel, and if an
environment variable for the panel is not set we don't attempt to
update the compatible string. Changes to the code also ensure that
when there are multiple compatible strings required for the panel
we can use them both.
