Package: raspi-firmware

Dear Maintainer,

Hello there,

Debian on rpi4 with GUI, I have tried Gnome/Xfce/Sway, all for me have
the same issues: (I am using rpi4 with 8GB RAM, as a daily desktop
machine, so I use it heavily, 24/7 it's running) 

Maine Issues:
* Some Application, I can't maximize and restore them (firefox-esr,
chromium) unless I enforce them to use wayland.
* Some application, I can't use them at all, can't open/can't run
properly (gimp), but when using the beta release, it works, as it uses
wayland by default.
* Freezing/locks up frequently, which is very annoying.

I am actually a Fedora user, but after recently bad news from Redhat
regarding the binary source of RHEL, I decided to move on.
Fedora 37/38 works just fine and smoothly on rpi4, specifically after
the hardware GPU acceleration driver supports has reached
mainline/upstream kernel "v3d", so I thought that means, debian should
do the same.
I noticed in Fedora, they have 'firmware' updated and has 'overlays',
and in their config.txt "dtoverlay=vc4-kms-v3d-pi4", so I have decided
to give that a try on debian after I talk to "gwolf".

All the above issues have solved by the following:

* I downloaded the latest (firmware-1.20230405) , unzipped it.
* Copied "firmware-1.20230405/boot/overlays" folder to /boot/firmware/
* Added these lines to /etc/default/raspi-firmware-custom
```````````````````````
# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d-pi4
dtoverlay=cma,cma-256
max_framebuffers=2

# Disable compensation for displays with overscan
disable_overscan=1
```````````````````````
* Reload raspi-firmware package:
dpkg-reconfigure raspi-firmware

* Then reboot the system.

Thank you so much all.

Sally.
