#
# Boot strap script for manufacturing
# Phase 1:
# Pre-programmed barebox loads gfrg200-mfg/bootstrap and executes it.  This
# script then turns on the red LED, upgrades the uloader and barebox, downloads
# gfrg200-mfg/pre-init and stores it in /env/bin/pre-init.
#
# Phase 1.5:
# New barebox boots up and executes /env/bin/pre-init which downloads and
# executes gfrg200-mfg/flash_image
#
# Phase 2:
# flash_image downloads and flashes the kernel and rootfs. It finally wipes the
# env partition to remove /env/bin/pre-init.
