# This script will be run by boot.scr if the kernel is detected
# on SD card. It will be searched in a FAT partition and /boot
# in an ext partition
#
# Please take this as a template and add to your distro as
# /boot/bootargs.scr together with a kernel (/boot/uImage)
#
# The partition number where the kernel was found is stored
# in the variable ${PARTITON}.
#
# Add/modify bootargs as needed, but please resist to do other
# fancy stuff here. And, you should not run a saveenv here as
# this may disturb booting from NAND!
