The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 1038/1085] overlays/README: Document that vc4-(f)kms requires
|
|
>=512MB
|
|
|
|
The firmware stops vc4-kms-v3d and vc4-fkms-v3d loading if the
|
|
system has less than 512MB of RAM. It can work if gpu_mem and
|
|
CMA heap size are set appropriately, but can't be guaranteed.
|
|
Document this restriction.
|
|
|
|
Also drops Eric's name from the overlay description as it
|
|
isn't relevant or accurate anymore.
