2020-06-22mb/google/volteer: Override power limits with SKU-specific limitsTim Wawrzynczak
Using guidance from Intel, a new set of power limits (PL1, PL2 & PL4) are available for TGL-U. They are dependent upon the SKU of the CPU that the mainboard is running on. Volteer is updated here to use these new limits. To accomplish this, the SoC chip config's power_limits_config member was expanded to an array, which can be indexed by POWER_LIMITS_*_CORE macros. Just before power limits are applied, the correct set of them is chosen from the array based on System Agent PCI ID. Therefore, a TGL board should have two sets of power limits available in the devicetree. BUG=b:152639350 TEST=On a Volteer SKU4 (4-core), verified the following console output: CPU PL1 = 15 Watts CPU PL2 = 60 Watts CPU PL4 = 105 Watts Change-Id: I18a66fc3aacbb3ab594b2e3d6e2a4ad84c10d8f0 Signed-off-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/42436 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nick Vaccaro <nvaccaro@google.com> Reviewed-by: Caveh Jalali <caveh@chromium.org>
2020-05-28soc/intel/common: Improve Type16 SMBIOS tablesPatrick Rudolph
Use CAPID0_A to provide information closer to reality. * Correctly advertise ECC support, max DIMM count and max capacity * CAPID0_A hasn't changed since SNB, but most EDS mark the bits as reserved even though they are still used by FSP. * Assume the same bits for Tiger Lake as for Ice Lake * Assume the same bits for Skylake as for Coffee Lake * Add CAPID0_A to Icelake headers The lastest complete documentation can be found in Document: 341078-002.

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>

2020-03-18soc: Remove copyright noticesPatrick Georgi
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.
