commit 5dedd2ddd03f02493d0a92ed1c74289b2ea87e64 Author: Pratik Prajapati pratikkumar.v.prajapati@intel.com Date: Fri Nov 18 14:36:34 2016 -0800
intel MMA: Enable MMA with FSP2.0
- Separate mma code for fsp1.1 and fsp2.0 and restructuring the code - common code is placed in mma.c and mma.h - mma_fsp<ver>.h and fsp<ver>/mma_core.c contains fsp version specific code. - whole MMA feature is guarded by CONFIG_MMA flag.
