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!
Regards, Simon
