Hi Mark,
Here is the patch series for enable Intel Broadwell/Haswell ADSP SRAM power gating feature.
Patches 0001~0002 merge wcp DRAM regions and correct the SRAM bit shift for it;
Patch 0003 add dummy read to workaround SRAM write missing bytes issue;
Patch 0004 will make SRAM start with all memory banks disabled, and enabled required banks during boot procedure.
thanks, Keyon
Changes in v2: * remove the Add persistent area alloc patch, for it is not so related with power gating feature.
