For a squashfs filesystem, the fragment table is followed by the following tables: NFS export table, ID table, xattr table.
The export and xattr tables are both completely optional, but the ID table is mandatory. The Linux implementation refuses to mount the image if the ID table is missing. Tables that are no present have their location in the super block set to 0xFFFFFFFFFFFFFFFF.
The u-boot implementation previously assumed that it can always rely on the export table location as an upper bound for the fragment table, trying (and failing) to read past filesystem bounds if it is not present.
This patch changes the driver to use the ID table instead and only use the export table location if it lies between the two.

Applied to u-boot/master, thanks!
