From: Randolph Sapp <[email protected]> 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.
