Changing the VL805 firmware whilst USB devices are attached may also cause
those devices to stop working until after the system is reboot.
FIRMWARE_RELEASE_STATUS
Specifies the release status of the firmware to apply. The default is 'critical'
which is the most stable production version. Alternatively, 'beta' may be selected
for development releases.
A 'critical' update is the latest stable production version and is normally
only updated after it has been tested via the 'beta' release.
Before selecting a firmware release directory this script checks whether there
is a board revision specific variant e.g. critical-c03111. If present then the
board-revision specific version is used in preference.
