[PATCH 0/3] k3-am62-pocketbeagle2: add board and variant support

[rs at ti.com]

From: Randolph Sapp <rs at ti.com>

Add initial board support for the PocketBeagle 2 from BeagleBoard.org. This is
based on the current official series from Robert Nelson [1] and work from Bryan
Brattlof [2] with some light modifications to protect against certain
configurations changes.

This borrows a lot from Phytec's current DDR fixup logic, as that seems to be
the most complete implementation of a dynamic DDR correction for K3 in tree
currently. Thanks Wadim Egorov and Dominik Haller for setting that up.

I've run coccinelle, checkpatch, and qconfig. That being said, this is my first
contribution to U-Boot so feel free to yell if something looks off. (I may look
into getting qconfig to respect that defconfig include logic in the future, as I
don't like it's suggestions currently. Let me know if it is intended behavior to
flatten that include into a single file.)
