[PATCH V5 00/17] board: ti: Add support for BeaglePlay

[Nishanth Menon]

Add support for BeaglePlay - rev 5

Full series: https://github.com/nmenon/fix-k3-dt-u-boot/commits/beagleplay-v4.2

Caveats:
* networking: pending https://lore.kernel.org/all/20230822121350.51324-1-rogerq@kernel.org/
* 32kclk and usb: pending:
  https://lore.kernel.org/u-boot/20230725185253.2123433-4-nm@ti.com/
  OR https://github.com/nmenon/fix-k3-dt-u-boot/commit/853b29d63c1ca642be316f1afb0fb778610dec46
  being properly resolved (NOTE: without this patch, wlan is broken in
  Linux as the 32kclk from SoC is incorrectly supplied to wlan as 25MHz)
* There seems to be a bug in Linux kernel with sdhci that seems to
  depend on u-boot initialization of sdhci for functionality.

CI loop check: https://github.com/u-boot/u-boot/pull/425 (whenever that
gets done I guess).

Bootlogs:
SD Boot: https://gist.github.com/nmenon/c74acb3a895053e05623e886df77c8fe
eMMC, no SD boot: https://gist.github.com/nmenon/16df3b8fc0e9102f29ebb7836b950a08
eMMC with SD card: https://gist.github.com/nmenon/042dbe7c08589e7bfe1919da1fedc545

Baseline: 97841de68043 (origin/next) Merge branch '2023-08-22-assorted-code-cleanups' into next

Changes since V4:
* Switched boot from distro_boot to bootstd - AM62 as a start will rely
  on txt env file.
* Cleanups around am625_init.c (new patches)
* Review comment fixups for documentation
* I have'nt picked up Mattijs's tested by since this is a different
  approach (bootstd Vs distro_bootcmd)
* Dropped the sdhci patches AND CFG_EXTRA_ENV_SETTINGS (Instead, we
  switch entirely to bootstd and move am62x-sk to bootstd along with
  it).
