[PATCH RFC 03/10] dt-bindings: arm: cpus: Add Cortina Systems CS7542 enable method
From: Fil Dunsky via B4 Relay
Date: Wed Sep 30 2026 - 03:03:39 EST
From: Fil Dunsky <filipp.dunsky@xxxxxxxxx>
On the CS7542 the bootloader parks the secondary Cortex-A9 core in a loop
that waits for an event and then jumps to the address found in a global
software register. Add the "cortina,cs7542-smp" enable method for it and,
as with the other release-address based methods, require cpu-release-addr
to point at that register.
