Hi Marek,

This define gives the possibility to copy entire image (including header - e.g. u-boot.img) from NOR parallel memory to e.g. SDRAM. The current code only supports loading the raw binary image (the u-boot.bin).
The legacy behavior is preserved, since other board don't enabled this option.
Sooooo, what's the usecase again ? ;-)
:-)
The use case is to allow u-boot.img being loaded from Parallel NOR. The current code only supports u-boot.bin.
Why is u-boot.bin (or the payload) not sufficient ? Why do you need the header ?
Well, the general use-case and code flow is that we load u-boot.img (or a FIT image) and if all else fails, fall back to assuming a .bin and a known address).
And exactly how is that whole image useful in RAM ? Sorry, I still do not see it, usually you just need the executable payload, although even that can be left in flash most of the time.
