Merge patch series "arm: Initial support for Analog Devices SC5xx boards"

Oliver Gaskell <[email protected]> says:

ADSP-SC5xx is a series of ARM-based DSPs.
This comprises the armv7 based SC57x, SC58x and SC594 series, and the
armv8 based SC598.

This patch series includes configurations, init code, and minimal DTs
to enable Analog Devices' evaluation boards for these SoCs to boot
through SPL and into U-Boot Proper, as well as devicetree schemas for
the added DTs.

This patch series depends on ("arm: Add Analog Devices SC5xx Machine
Type") (https://lists.denx.de/pipermail/u-boot/2024-April/552043.html)
