Cool! I can add this to the series :)
Thanks for reviewing everyone

Hi Bryan,
This series will introduce basic support (SD and UART) support for Texas
Instruments AM62Ax SK EVM.
The am62ax shares many of the same features as the am62x however it uses
a new 32bit controller and therefore depends on the patch I sent last
week updating the macros used by the k3-ddrss ram driver[0].
Here is some proof of life & more documentation if you're interested :)
Bootlog:https://paste.sr.ht/~bryanb/e0a418ba7dd452749d2dd1efb5e91b2875a01708

Does this board need a readme for how to build the firmware, these
days there generally needs to be ATF and probably a slew of other
firmwares linked into a FIT image or similar to build the entire
firmware bundle, a readme would likely be a useful addition for people
getting started if there's not a generic TI 64 bit build doc, and if
there is that likely needs an update to include this SoC/board. I
didn't see anything that looked like that in the file list below.
Agreed, something under doc/board/ti/ is needed as well for the series,
thanks!
I see we do have some files at board/ti/{j721e,j721s2}/README with some
good info on all this firmware source/building. Much of that info is
common and could be factored out into a "generic TI 64 bit build doc".
