Bootloader needs to be at 0x400 for IMX6 devices. That is ignored by
pmbootstrap which places the GPT header there. Revert to msdos partition
table style to workaround that bug.
Near-mainline kernel is feature-complete since quite some time, so lets
use that as a default also to simplify boot process, since downstream kernel
depends on various blobs loaded into memory by the bootloader.
Get rid of quirks required in boot process for mainline kernels
also by using a near-mainline u-boot.
Prepare for handling rev b devices.
Keep Downstream kernel to be able to optimize/compare EPD operation
Mesa behaves again, #1658 is fixed, so lets re-revert MR 3306.
Lets also add the dependency to the other devices using the same
graphics driver.
[ci:skip-build] Already built successfuly on CI in MR
Having mesa-dri-gallium installed causes Xorg to crash. See #1658.
Furthermore, display works without at least with near-mainline kernel,
tested with osk-sdl and xfce4.
So if specific applications depend on it, it should be added as a
dependency there.
This reverts MR 3306
This is just a hotfix, Xorg/mesa should be tamed to not crash here
but analyzing that costs time.
There is no need to duplicate things over and over again.
Also load the waveform in initramfs before loading display
modules. That is early enough to have a working display in
initramfs.
Support the downstream kernel and a close-to-mainline fork. Waveform
data for the eInk display and the Wi-Fi driver are not included yet.
Everything else should work.
