[PATCH openbmc 0/9] Change Read/Write overlay filesystem to jffs2

[OpenBMC Patches]

This series updates the build and init scripts to allow, nee require, that the rwfs be a jffs2 instead of our former ext4 filesystem.  

An kernel command line parameter clean-rwfs-filesystem, is also detected to clean the filesystem back to the whitelisted files.

The init and update scripts now use blkid to detect known filesystems, and assume jffs2 if blkid produces no output (as there is no current probe for jffs2).  The erased nor is also considered jffs2 and the kernel is happy to mount and use such a flash partition.

The requirement can be turned off with a 1 word edit to a flag in the init script.  Another flag can be
set to allow images to be built into an initrd for netboot updating.  Images can also be downloaded at the debug-init-sh sulogin shell if that is set in the command line.

The build system now initializes the image to 0xFF, the nor erase value, to allow the filesystem to be implicit.

There is also a  correction to an error path takeover message.
I have exercised all paths of the final init script.
