kernel: mtdsplit_squashfs: Align with the erase-block size
On most image types the rootfs ends at an erase-block. However, at least with brnImages this is not the case: while the partitions are aligned with the erase-block size there is a 12 byte footer at the end of the partition which must not be touched by any filesystem. This lead to a rootfs_data partition which was not aligned properly (and thus ended up being readonly): 0x000000480000-0x00000085a800 : "rootfs_data" (128 KiB EB) Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> SVN-Revision: 48263
