Self-update is preferred to using recovery.bin because it avoids modifiy the
boot partition in order to rename recovery.bin after use. Since the 2711 ROM
does not support network or USB MSD loading of recovery.bin self-update has to
be used with other boot modes anyway.
If RPI_EEPROM_SELF_UPDATE=1 then avoid installing recovery.bin so long as the
current bootloader version supports self-update from SD/MMC and that doesn't
look as though SELF_UPDATE has been disable in the EEPROM config.
Enable Network Install in the default bootloader release.
This release is signed with the secure-boot key and supports
the new HTTP boot-order for downloading signed boot images for
automated provisioning systems.
