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.

2021-01-24soc/intel/cnl: use Kconfig to determine PCH typeMichael Niewöhner
We already know the PCH type at build time, so there is no need to do runtime detection. Thus, use Kconfig and drop `get_pch_series()`.

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.

Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2019-06-28soc/intel/cannonlake: fix use of legacy 8254 timerMatt DeVillier
FSP sets the use of the 8254 timer via the Enable8254ClockGating UPD, which defaults to enabled, overriding what is set by coreboot. Per the FSP integration guide, this UPD needs to be disabled when a legacy OS is booted (ie, when SeaBIOS is used as the payload). Add a Kconfig option to set the UPD properly based on payload selection, and remove the existing coreboot code in lpc.c since it is either ineffective or being overridden by FSP. Test: build/boot out-of-tree WHL board with both SeaBIOS and Tianocore, ensure 8254 timer usage set correctly for each.
