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.

2020-05-20soc/intel/tigerlake: Move PMC PCI resources under PMC deviceTim Wawrzynczak
Historically in coreboot, the PMC's fixed PCI resources were described by the System Agent (the MMIO resource), and eSPI/LPC (the I/O resource). This patch moves both of those to a new Intel SoC-specific function, soc_pmc_read_resources(). On TGL, this new function takes care of providing the MMIO and I/O resources for the PMC. BUG=b:156388055 TEST=verified on volteer that the resource allocator is aware of and does not touch these two resources: ("PCI: 00:1f.2 resource base fe000000 size 10000 align 0 gran 0 limit 0 flags f0000200 index 0 PCI: 00:1f.2 resource base 1800 size 100 align 0 gran 0 limit 18ff flags c0000100 index 1") Also verify that the MEM resource is described in the coreboot table: ("BIOS-e820: [mem 0x00000000fe000000-0x00000000fe00ffff] reserved") Verified the memory range is also untouchable from Linux: ("system 00:00: [mem 0xfe000000-0xffffffff] could not be reserved") Change-Id: Ia7c6ae849aefaf549fb682416a87320907fb3fe3 Signed-off-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/41385 Reviewed-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

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.
