* recovery: Restore recovery_wait option Restore the recovery_wait config.txt option. If this option is set then recovery.bin will not rename itself or reboot. Instead flash the activity LED on completion. This option can be useful when creating an SD card to erase the EEPROM or program the RPIBOOT gpio on multiple devices. If recovery_wait=1 and recovery.bin is run from the SD card then indicate success of erase_eeprom=1 or program_rpiboot_gpio=N was set instead of requiring the EEPROM to be updated. * Load RP1 firmware whilst DDR is initialising * Allow longer overlay file paths load_dtoverlay uses the variable "filename" to hold the full path to an overlay. As such it should be declared using LDFILEPATH_MAX, not LDFILENAME_MAX. See: raspberrypi/firmware#2004
