soc/intel/jasperlake: Add Jasper Lake SoC support This is a copy patch from Tiger Lake SoC code. The only changes done on top of copy is changing below configs: 1. SOC_INTEL_TIGERLAKE -> SOC_INTEL_TIGERLAKE_COPY 2. SOC_INTEL_JASPERLAKE -> SOC_INTEL_JASPERLAKE_COPY 3. SOC_INTEL_TIGERLAKE_BASE -> SOC_INTEL_TIGERLAKE_BASE_COPY We started with initial assumption that JSL and TGL can co-exist. But now we see the SoC code in Tiger Lake is relying on too many compile-time directives to make two SoCs co-exist. Some of the differences are listed below: -> Kconfig: Multiple Kconfig options using if SOC_INTEL_{TIGERLAKE/JASPERLAKE} -> GPIO: GPIO communities have their own differences. This requires conditional checks in gpio.asl, gpio.c, gpio*.h, pmc.h and gpio.asl -> PCI IRQs: Set up differently for JSL and TGL -> PCIe: Number of Root ports differ. -> eMMC/SD: Only supported on JSL. -> USB: Number of USB port are different for JSL and TGL. -> Memory configuration parameters are different for JSL and TGL. -> FSP parameters for JSL and TGL are different. The split of JSL and TGL SoC code is planned as below: 1. Copy Tiger Lake SoC code as is, and change SoC Kconfig to avoid conflicts with current mainboard builds. 2. Clean up TGL code out of copy patch done in step 1. Make it JSL only code. The SoC config still kept as SOC_INTEL_JASPERLAKE_COPY. 3. Change JSL SOC Kconfig from SOC_INTEL_JASPERLAKE_COPY to SOC_INTEL_JASPERLAKE, dedede and jasperlake_rvp boards can bind to SoC code from soc/intel/jasperlake. This step establishes Jasper Lake as a separate SoC. 4. Clean up current JSL code from TGL code. This step establishes Tiger Lake as a separate SoC.
