Rename the root partition to "rootfsA" in the off-chance the user may someday be interested in implementing some sort of whole-partition update mechanism. Signed-off-by: Trevor Woerner <twoerner@gmail.com>

# KERNEL_DEVICETREE follows the pattern of
|
|
# 'rockchip/${SOC_FAMILY}-${BOARD}.dtb' which is required when compiling
|
|
# the kernel so the kernel's Makefile can find the device tree
|
|
#
|
|
# when using extlinux with a fitImage the device tree is contained in the
|
|
# fitImage
|
|
#
|
|
# however for non-fitImages it is not found at
|
|
# $UBOOT_EXTLINUX_FDTDIR/rockchip/$KERNEL_DEVICETREE but rather at
|
|
# $UBOOT_EXTLINUX_FDTDIR/$KERNEL_DEVICETREE therefore we need to strip off
|

# the 'rockchip/' part for extlinux non-fitImage builds
