From bdd2772f1d1f822acedb7dadf9d5978ce2dbc2e2 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sun, 17 Jan 2016 10:40:51 +0000 Subject: kernel: mtdsplit: add support for brnImages This adds brnImage (used with the brnboot bootloader) firmware parsing support. brnboot verifies the integrity of the firmware stored on the "Code Image" partitions by looking at the 12 byte footer at the very end of the partition. This footer contains the checksum of the original brnImage (kernel + rootfs/squashfs) and must not be touched (by our JFFS2 rootfs_data - otherwise the image will not be bootable anymore). Big thanks to Mathias Kresin for analyzing the brnImage structure and finding out the information how to keep images valid even when adding a nested rootfs_data partition.
