avoiding loopback for squashfs

Can the squashfs be put in its own partition (or similar) rather than as a file on some other filesystem? This might remove the need for the loopback step and possibly even the separate initial minimal root system the article suggests.

We use squashfs as the root on a NOR type flash with the mtd drivers. Something like this:

mksquashfs * ../root.squashfs -all-root -noappend

Then on the target device:

flashcp root.squashfs /dev/mtd1

The kernel command line to boot is then:

root=1f01 rootfstype=squashfs
