(I recently wondered whether TX1 may be missing some, as I needed multiple tries to boot the kernel successfully there - TF-A 2.1 didn't work there, so some more investigations TBD. R28.3.0 still wasn't booting U-Boot ~2019.04, I needed R24.2.2 still as you once suggested.)
Hmm. Are you building your own copy of ATF (you mentioned 2.1; I can't recall what version we ship)?
v1.2
FWIW, my usptream U-Boot test system uses L4T r28.1 to test Jetson TX1 and TX2. It does test DHCP/TFTP, but not EFI or booting a kernel.
So it turned out that what I last tried with R28.3.0 was downstream U-Boot plus upstream TF-A v2.1. I've been digging into this and have a draft fix for upstream TF-A, a BL2 parameter layout change:
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1317
With this I can boot into -rc4 on R28.3.0. Haven't re-checked R24 yet.
Some U-Boot side EFI and non-EFI problems (as well as kernel deferred probing problems) remain to be investigated.
