This is just doing what many other aarch64 platforms do, of skipping the SPL phase in Cortex-A because something else has already done any required initialization, unless I'm reading all of this wrong. So my feedback is: - It's not "semi-falcon", it's just "no SPL". Naming differences, if any, should be done with that in mind. - You should make sure to structure this so any K3 platform *could* take advantage. I seem to recall part of the rationale for the current approach is that some variants might only have a little SRAM (512k? 256k?) while others might have 1-2M and so easily fit U-Boot in SRAM prior to relocation. It sounds like this specific family has a large enough lower memory bound. -- Tom
