This series introduces a method to dynamically set the AM62 A53 CPU frequency
based on its speed grade. It adds a new function to retrieve the A53 frequency
value by reading the speed grade from the hardware. Subsequently, it adjusts the
Cortex R5 device tree at runtime  with the frequency value before initializing
the remote processor.

João Paulo Goncalves

Applied to u-boot/master, thanks!
