2021-01-31soc/intel/*: drop incomplete and unneeded check for DMI SRLOCKMichael Niewöhner
Before enabling IO decode ranges, current code checks if the DMI SRLOCK is set to prevent inconsistencies between LPC PCI cfg registers and LPC DMI registers, when the latter are locked. DMI SRLOCK only applies to PCHs with on-package DMI, but not to PCH-H, PCH-S and others with discrete PCH packages. So this check is at least incomplete. Further, the lock gets applied by FSP and gets reset on a warm reset. Thus, there is no case where the lock would be already set at the places where the DMI registers get written currently. Drop the checks for the reasons mentioned above.

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.

2020-11-29soc/intel: Configure P2SB before other PCH controllersFurquan Shaikh
This change updates bootblock_pch_early_init() to perform P2SB configuration before any other PCH controllers are initialized. This is done because the other controllers might perform PCR settings which requires the PCR base address to be configured. As the PCR base address configuration happens during P2SB initialization, this change moves the p2sb init calls before any other PCH controller initialization.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? 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.
