# Simple script to update flash. The kernel module rtas_flash does
# the real work at reboot time.
# This script has minimal dependencies so it can operate in a rescue
# environment. This is probably overkill since it is easy enough to
# flash without this script.

# For now firmware can only handle 4k pages. At some point in the
# future they will be able to handle large pages. When that (hopefully)
# happens we will need to use getconf to retrieve the systems page size.
