+# U-Boot with the datachk patchset requires image sizes, offsets,
+# and checksums to be provided in the U-Boot environment.
+# This script is based on the dualboot version for devices that come with 2 OS partitions.
+# For Senao boards with a "failsafe" partition image, the process is almost the same.
+# Instead of booting a secondary instalation on checksum failure,
+# the failsafe image is booted instead.
+# These boards also use the OKLI lzma kernel loader and mtd-concat
+# So the kernel check is for the loader, the rootfs check is for kernel + rootfs
