From 2c1202b765f2f7e885dbb5abaefb7c057c2e4167 Mon Sep 17 00:00:00 2001

Subject: [PATCH] overlays: Add disable-emmc2
Add a new overlay that disables the EMMC2 controller on BCM2711.
This can be useful on a Compute Module 4 if the onboard EMMC2
storage is unreliable and the system can be booted by other
means e.g Network / USB.
