2020-01-23soc/intel/common: Update SA bit fields as per EDSSubrata Banik
This patch updates system agent related registers bit definitions as per EDS. For example: As per CNL/ICL EDS MCHBAR register base is between bit 16-38 but coreboot programming was not aligned with EDS previously. CNL EDS doc number: 566216 Also provide provision to program 64bit values as per SA EDS definitions TEST=Dump MCHBAR in coreboot and ASL shows same 32 bit value.

2020-01-10soc/intel/{apl,cnl,icl,skl,tgl}: Make above 4GB MMIO resource properSubrata Banik
This patch ensures coreboot is not publishing above 4GB mmio resource if soc common config "enable_above_4GB_mmio" not enable. Publishing unnecessary 4GB above MMIO resource with wrong base and size is causing problem while working with discrete GPU.

2019-11-04soc/intel: skl,cnl,icl: rely on TOLUM as cbmem_top returned by FSPMichael Niewöhner
Instead of doing our own calculations, rely on TOLUM returned by FSP for cbmem_top. This (hopefully) saves us from making mistakes in weird calculations of offsets and alignments. Further this makes it easier to implement e.g. SGX PRMRR size selection via Kconfig as we do not have to make any assumptions about alignments but can simply pass (valid) values to FSP.

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.
