Works on sdcard and QSPI NOR boot on phycore-imx8mp board.
Hm, the subject of that patch mentions booting through uuu, and here you mention imx8mp. I'm quite interested in that combination, as it doesn't seem that the imx8mp_evk in mainline U-Boot (signed or not) can be booted via uuu. Does serial download work on phycore-imx8mp?
As I mentioned in https://lore.kernel.org/u-boot/0996154d-774c-607f-8b5c-9cc0d268ecaa@prevas.d... , I've bisected the start of it working in the NXP fork to a specific commit, but I can't figure out what part of that is really responsible (and if it's just that that commit enables some CONFIG_* symbols for imx8mp_evk, the real meat is likely in earlier commits adding the code that thus gets enabled).
Any ideas?
