hints and pointers.

+The AM62lx support currently depends on a modified downstream version of the TF-A. See
+https://lore.kernel.org/20250617090142.3000882-1-s.hauer@pengutronix.de for a patch
+series to be applied on the Downstream TF-A. Be aware that barebox might need further
+changes to be compatible with future upstream TF-A support. Specifically the SCMI clock
+IDs used in the assigned-clock-parents properties might not match the future upstream
+solution.
