Re: [U-Boot] FIT image for falcon boot
Simon,
I made it work. A patch set will be sent later (much later) after I clean up and finish the project on hand.

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?

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!
