Is it possible to specify squashFS images in an .its file?  If so, anyone
have an example or a pointer to the docs I've been searching for?
Hi Mark,
It is possible, here is an example I have used on an NXP LS1043 board:
/dts-v1/;
As Matthew's example shows it's totally doable. Furthermore it's not just
squashfs it could be any valid initrd. As long as your kernel is configured
to expect it u-boot will pass it along.
On that note last time i looked most if the general kernel defconfigs
didn't have squashfs enabled.
