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.
