[PATCH 00/15] board: ti: Add support for BeagleBone AI-64

[Nishanth Menon]

Cleanups for J721e/J7200 and add support for BeagleBone AI-64

Based off:
master 07fe79c93c5c Merge tag 'i2cfixes-for-v2024-01-rc2' of https://source.denx.de/u-boot/custodians/u-boot-i2c

BeagleBone AI-64 is introduced without EEPROM detection and cleanups
to j721e evm configuration is done to facilitate that. based on when
and timing of [1] is merged in, we can introduce an equivalent patch or
squash similar patch in for beagleboneai64.

Boot uses stdboot as default - so we also transition j721e over to
sdboot along with it.

Fixes a breakage with HBMC that was getting in my way of testing, but I
have'nt focussed on converting j7200 to stdboot - but probably a minor
patch similar to that in this series for j721e.

What works:
* emmc, sd, dhcp, basic i2c gpio etc..
* DDR looks stable as well.

TODO:
* PMIC support will need to be added for AVS to be active - something to
  do once upstream kernel gets that support
* USB boot is broken (or was just noticed) - some sort of regression with
  serdes is my best guess.
* We could potentially enable something like nvme boot as well if we can
  make PCIe work
