This recipe will allow yocto images to support configuring and updating
the bootloader on Raspberry Pi 4 boards. So far this recipe just
includes the commands and firmware with no automation for updates.
Note that this depends on nvmem-rmem support either built into the
kernel or as a module. If that is not part of the kernel the scripts
will error out suggesting that the vcgencmd command from the userland
package is missing. Whilst using vcgencmd from the userland package does
work, it would lead to a conflict with the mesa backend for graphics, so
using the kernel interface is recommended.
