[PATCH 1/2] arm: mach-k3: am62: move scratch board area to HSM RAM
From: Kamlesh Gurudasani On high security devices, ROM enables firewalls to protect the OCSRAM region access during bootup. Only after TIFS has started (and had time to disable the OCSRAM firewall region) will we have write access to the region. So, move scratch board area to HSM RAM.
