From c7e576590e45f9fb86a9d74fa66b4fd4f8eca803 Mon Sep 17 00:00:00 2001

Subject: [PATCH] ARM: dts: keystone: Remove reg entry from the sram node
Currently the reg entry reserves the whole MSMC ram range to be used
only through the mmio-sram driver. (See LCPD-7801)
Given that other modules (like CMEM) also currently reserve memory from
MSMC, the reg entry which takes over the whole memory breaks those
functionality. So currently recommending to remove this for now.
Still the ranges entry will capture the total memory available.
This will allow module like CMEM to reserve and use a non-overlapping
section of memory not marked reserved by the sub nodes here.
Resolves current issue with CMEM module reporting error allocating MSMC
memory.
