[PATCH v2 0/9] Use mmio-sram driver for Keystone MSMC RAM

Hi,

The Keystone 2 family of SoCs have an on-chip RAM called the
Multicore Shared Memory (MSM) RAM. This RAM is accessible through
the Multicore Shared Memory Controller (MSMC). This series represents
these on-chip RAMs as sram nodes so that the memory allocations
can be managed by the in-kernel mmio-sram driver.

This is v2 of the previous series [1], and now includes 4 additional
patches that reserve the portions of the MSMC RAM used by the
Keystone Boot Monitor. The first 5 patches are essentially the same
as in v1, with minor commit description updates for using the proper
SoC names, but no code changes.

Patches baselined on 4.10-rc1.

regards
Suman
