Simon,
I made it work. A patch set will be sent later (much later) after I
clean up and finish the project on hand.

OK, sounds good!
IMO some of the motivation for falcon boot is U-Boot running slowly
with the cache off :-)

My target is to boot up Linux under 800ms. I have achieved that but with
minimum Linux drivers loaded. I don't have much time budge for U-Boot.
Falcon boot cuts U-Boot time down to ~400ms (including loading FIT
image). I have cache enabled after loading the trusted firmware (our
implementation) as soon as the DDR is ready.

Yes that is a pretty tight limit - sounds like you have things humming nicely!

Guys,
You were discussing loading FIT image for falcon boot about a year ago.
I wonder if there is any follow-up on this topic?
