2017-10-19soc/intel/cannonlake: Use EBDA structure to store soc reserve memory sizeSubrata Banik
Avoid calling calculate_dram_base() function to get chipset reserved memory size during pci resource allocation. Rather use EBDA to store chipset reserved memory size while calling cbmem_top_int(). This patch avoids one extra calculate_dram_base() call. BRANCH=none BUG=b:63974384 TEST=Ensures DRAM based resource allocation has taken care of Intel SoC reserved ranges.

2017-10-18soc/intel/cannonlake: Calculate soc reserved memory sizeSubrata Banik
This patch implements soc override function to calculate reserve memory size (PRMRR, ME stolen, PTT etc). System memory should reserve those memory ranges. BRANCH=none BUG=b:63974384 TEST=Ensures DRAM based resource allocation has taken care of intel soc reserved ranges.

2017-10-18soc/intel/cannonlake: Use EBDA area to store cbmem_top addressSubrata Banik
This patch uses BIOS EBDA area to store relevent details like cbmem top during romstage after MRC init is done. Also provide provision to use the same EBDA data across various stages without reexecuting memory map algorithm. BRANCH=none BUG=b:63974384 TEST=Ensures HW based memmap algorithm is executing once in romstage and store required data into EBDA for other stage to avoid redundant calculation and get cbmem_top start from EBDA area.

2017-10-18soc/intel/cannonlake: Refactor memory layout calculationSubrata Banik
This patch split entire memory layout calculation into two parts. 1. Generic memory layout 2. SoC specific reserve memory layout. usable memory start = TOLUD - Generic memory size - - soc specific reserve memory size.
