[PATCHv3 0/4] 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.

Now that the various memory issues have been resolved we can clearly see at
runtime that there's an issue with the current device. One of our reservations
overlaps with the u-boot stack. To get around this we'll need to change the
relocation address to something we know will not collide.
