Usage:

Creates and SD card image which programs the OTP on a Pi 4B or Pi 400
Creates an SD card image which programs the OTP on a Pi 4B or Pi 400
to select a GPIO on the 40-pin header for use as the rpiboot GPIO.
Once programmed, if this GPIO is pulled to ground at power on the SoC
bootrom will boot into rpiboot provisioning mode.

SoC bootrom will boot into rpiboot provisioning mode.
This setting permenantely modifies the device confiuration and cannot
be undone or changed.
This setting _permanently_ modifies the device confiugration - it cannot
be undone or changed, ever.
The SD image will be written to images-2711/pi4-program-rpiboot-gpioN.zip
and can be flashed using Raspberry Pi Imager to a spare SD card.
As with programming the bootloader EEPROM insert the card in the
Raspberry Pi, power on and wait for the green LED to flash.
The SD image will be written to images-2711/pi4-program-rpiboot-gpioN.zip,
where N is the number of the chosen GPIO, and can be flashed using
Raspberry Pi Imager to a spare SD card. As with programming the bootloader
EEPROM, insert the card in the Raspberry Pi, power on and wait for the
green LED to flash.
gpio_num: Select the rpiboot GPIO number from 2,4,5,6,7 or 8.
