-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.
