[meta-xilinx] read-only-fs

[Bishop, Mark (STRT)]

Thanks for your help on the squashfs stuff.

One last thing though when I try and create a read-only root fs in petalinux.  I will be adding an overlay or some sort of R/W partition but it's just going to be saving ssh keys and a minor device config file.

I edited project-spec/meta-user/conf/petalinuxbsp.conf and added:
EXTRA_IMAGE_FEATURES +="read-only-rootfs"
but now I get these errors when I build.
