== DT loading ==
Previously, boards used the FDT blob embedded into U-Boot (via OF_SEPARATE). However, most Qualcomm boards run U-Boot as a secondary bootloader, so we can instead rely on the first-stage bootloader to populate some useful FDT properties for us (notably the /memory node and KASLR seed) and fetch the DTB that it provides. Combined with the memory map changes above, this let's us entirely avoid configuring the memory map explicitly.
Running U-Boot as a secondary bootloader is the degenerate case. Are there any Qualcomm boards where U-Boot runs first? In that case, perhaps the DT could be used in SPL to determine the memory size as well?
(this series is fine to me, BTW)
