Merge patch series "Add support for TI AM6254atl SiP"

Anshul Dalal <[email protected]> says:

This patch series adds support for AM6254atl SiP (or AM62x SiP for
short) to U-Boot.

The OPN (Orderable Part Number) 'AM6254atl' expands as follows[1]:

AM6254atl
     ||||
     |||+-- Feature Lookup (L indicates 512MiB of integrated LPDDR4)
     ||+--- Device Speed Grade (T indicates 1.25GHz on A53 cores)
     |+---- Silicon PG Revision (A indicates SR 1.0)
     +----- Core configuration (4 indicates A53's in Quad core config)

AM62x SiP provides the existing AM62x SoC with 512MiB of DDR
integrated in a single packages. The first 4 patches in the series
are cherry-picked from the devicetree-rebasing repository at
'v6.18-rc2-dts'.
