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 :)

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".
Cool! I can add this to the series :)
Thanks for reviewing everyone ~Bryan
