2019-10-26soc/intel: common,skl,cnl,icl: drop reserved mmio memory size calculationMichael Niewöhner
Remove the calculation of the Reserved Intel MMIO Memory size from systemagent and memmap, since it is not needed. The size is used in SA to calculate the space between cbmem_top and TSEG without DPR and Chipset Reserved Memory. Since this will always be equal to 0, the reservation will be skipped and TSEG, DPR and Chipset Reserved Memory will get reserved alltogether. By reading the code and pratical testing we figured out that: - TSEG - DPR - reserved - top_of_memory == 0 - TSEG - DPR - reserved == top_of_memory This means the whole block will never reserve anything because it is always 0. Hence the code can be removed for simplification.

2019-10-21Revert "soc/intel/cannonlake: Remove DMA support for PTT"Jeremy Soller
This reverts commit d5018a8f78b9e1f0b7d3d1be298cba9716b10c6c. Reason for revert: Breaks boot on Whiskey Lake-U boards Both System76 and Purism have had memory initialization failures when this patch is applied, with the following error message: Failed to accommodate FSP reserved memory request! An extra 4096 bytes needs to be reserved for the FSP on these systems, and reinstating the PTT reservation does this as expected. PTT is enabled for the System76 galp3-c in the ME configuration, which is why the behaviour is different.
