The VideoCore blobs for the Raspberry Pi 1, 2, 3, Zero, Zero W and Zero
2 W are differents from the ones for the Raspberry Pi 4 and the Compute
Module 4.
The VideoCore blobs for the Raspberry Pi 4 are named with a 4[1] (i.e.
start4.elf, start4x.elf, start4db.elf and start4cd.elf).
This precises which VideoCore firmware blob files are present on the
Raspberry Pi 1, 2, 3, Zero W, Zero 2 W and which files are present on
the the Rapsberry Pi 4 and the Compute Module 4.
Note: The VideoCore blobs for the Raspberry Pi 5 are self-contained in
its bootloader EEPROM[1][2]; there is no additional files for pi5.
