2021-01-25soc/intel/{skl,cnl,xsp,icl,tgl,ehl,adl,jsl}: use common LPC mirroringMichael Niewöhner
Drop the old, redundant code for mirroring LPC registers to DMI and make use of the new common code. Select the new Kconfig option for LPC DMI mirroring by the option SOC_INTEL_COMMON_PCH_BASE, which is selected by platforms starting with SPT, except APL and Xeon-SP. For Xeon-SP, select DMI and the new Kconfig directly. APL, even though it's younger than SPT, does not need mirroring. Test: Set LGMR address by calling `lpc_open_mmio_window` and check that both the PCI cfg and DMI LGMR register get written correctly. Tested successfully on clevo/cml-u.

2021-01-20soc/intel/*: drop broken LPC mmio codeMichael Niewöhner
The code for setting the LPC generic memory range uses an array of fixed address ranges not needing explicit decoding, to decide if the address needs to be written to the LGMR register. Most platforms only mistakenly add the PCH reserved mmio range, that is not decoded generally, effectively breaking the mechanism. Only APL uses the array correctly. That code, in it's current state, does not work (except for APL) and currently, there is not a single user. Thus, drop it before people start using it.

2021-01-08soc/intel: Drop `dev` parameter from soc_get_gen_io_dec_range()Furquan Shaikh
This change drops the parameter `struct device *dev` from the function `soc_get_gen_io_dec_range()`. This function uses the parameter dev to get a pointer to config structure for extracting the decode ranges configured by mainboard in device tree. However, there is no separate chip driver for the LPC device which means that the SoC code can use `config_of_soc()` to get to SoC chip config instead of using the LPC device. This change is being done in preparation to clean up the device tree/chip config access in early stages that allows for optimizing the inclusion of device tree elements in the early stages.

2020-03-28soc/intel/jasperlake: Add Jasper Lake SoC supportAamir Bohra
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.
