2019-11-16soc/intel: Implement PCIe RP devicetree update based on LCAPNico Huber
Most of the current implementations for FSP-based platforms make (sometimes wrong) assumptions how FSP reorders root ports and what is specified in the devicetree. We don't have to make assumptions though, and can read the root-port number from the PCIe link capapilities (LCAP) instead. This is also what we do in ASL code for years already. This new implementation acts solely on information read from the PCI config space. In a first round, we scan all possible DEVFNs and store which root port has that DEVFN now. Then, we walk through the devicetree that still only knows devices that were originally mentioned in `devicetree.cb`, update device paths and unlink vanished devices. To be most compatible, we work with the following constraints: o Use only standard PCI config registers. o Most notable, don't try to read the registers that configure the function numbers. FSP has undocumented ways to block access to non-standard registers. o Don't make assumptions what function is assigned to hidden devices. The following assumptions were made, though: o The absolute root-port numbering as documented in datasheets matches what is read from LCAP. o This numbering doesn't contain any gaps. o Original root-port function numbers below a PCI device start at function zero and also don't contain any gaps.

The devicetree is not made for user-choosable options, thus introduce Kconfig options for both SGX and the corresponding PRMRR size. The PRMRR size Kconfig has been implemented as a maximum value. At runtime the final PRMRR size gets selected by checking the supported values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest to the chosen one. When "Maximum" is chosen, the highest possibly value from the MSR gets used. When a too strict limit is set, coreboot will die, printing an error message.

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.

Currently SPI bus id is used to map to the controller in order to set the controller state. In certain platforms SPI bus id might not be exactly the same as GSPI bus id. For example, in Intel platforms SPI bus id 0 maps to fast spi i.e. SPI going to the flash and SPI bus id 1 .. n map to GSPI bus id 0 .. n-1. Hence using SPI bus id leads to mapping to the GSPI controller that is not enabled. Use the GSPI id bus so that the right controller is set to active state.
