Argh, your HTML e-mail is a mess.

Apparently, not in the case of RPi5, because the patch from Athaariq
has:

+BR2_PACKAGE_RPI_FIRMWARE=y
+BR2_PACKAGE_RPI_FIRMWARE_VARIANT_PI5=y
+BR2_PACKAGE_RPI_FIRMWARE_CONFIG_FILE="board/raspberrypi5/config_5.txt"

so neither BR2_PACKAGE_RPI_FIRMWARE_INSTALL_DTBS nor
BR2_PACKAGE_RPI_FIRMWARE_INSTALL_DTB_OVERLAYS are enabled. Therefore
the rpi-firmware package does not install DTBs or DTBOs.

OK, but for the time being, I wouldn't mind to see a RPi 5
configuration merged that works in the current setup. Then we can
improve later on. We really want to have a RPi5 configuration in
Buildroot soon.
