Hi,

I was wondering about the correct load address for a devicetree in FIT. Normally, the dtb can be anywhere in RAM, so it doesn't make sense to force it to a specific address with a 'load =' FIT directive.

With bootm, the first overlay, but then fail with with: "Overlayed FDT requires relocation" The reason is that bootm_find_other() will want to apply the overlays with the FDT in-place. This would overwrite the FIT image. But later, in boot_relocate_fdt(), it goes ahead and relocates the FDT anyway. So why not relocate the FDT, and then apply the overlays?

I also like the solution when booting FITs with SPL_LOAD_FIT_SIMPLE. In this case, the FDT is placed right after the firmware or OS binary, unless the 'load =' address is given in the FIT.
