2018-01-25drivers/i2c/designware: reduce API complication for bus configAaron Durbin
Right now dw_i2c_get_soc_cfg() is expecting the SoC to implement that callback for obtaining the bus config. However, we're currently forcing another parameter of struct device so one can do the lookup. This works for Intel-based systems since the struct device was needed to program the BAR, etc. However, from an API standpoint, it just complicates matters by needing to obtain the struct device. The SoC already has knowlege of its own devices so it can get the config itself by bus number. Therefore, remove that contraint from the API.

2017-11-15soc/intel: Enable ACPI DBG2 table generationDuncan Laurie
Enable the ACPI DBG2 table generation for Intel boards. This is a Microsoft defined ACPI extension that allows an OS to know what the debug port is on a system when it is not enabled by the firmware, so it does not show up in the coreboot tables and cannot be easily found by a payload. broadwell: Use byte access device, set up only when enabled since it relies on the port being put in byte access mode and using this serial port for debug was not standard in this generation. skylake: Enable for the configured debug port. Skylake uses intelblocks for UART but not ACPI. common: Enable for the configured debug port. This affects apollolake and cannonlake. Tested by compiling for apollolake/broadwell, tested by reading the DBG2 ACPI table on kabylake board and using IASL to dump: [000h 0000 4] Signature : "DBG2" [004h 0004 4] Table Length : 00000061 [008h 0008 1] Revision : 00 [009h 0009 1] Checksum : 3B [00Ah 0010 6] Oem ID : "CORE " [010h 0016 8] Oem Table ID : "COREBOOT" [018h 0024 4] Oem Revision : 00000000 [01Ch 0028 4] Asl Compiler ID : "CORE" [020h 0032 4] Asl Compiler Revision : 00000000 [024h 0036 4] Info Offset : 0000002C [028h 0040 4] Info Count : 00000001 [02Ch 0044 1] Revision : 00 [02Dh 0045 2] Length : 0035 [02Fh 0047 1] Register Count : 01 [030h 0048 2] Namepath Length : 000F [032h 0050 2] Namepath Offset : 0026 [034h 0052 2] OEM Data Length : 0000 [036h 0054 2] OEM Data Offset : 0000 [038h 0056 2] Port Type : 8000 [03Ah 0058 2] Port Subtype : 0000 [03Ch 0060 2] Reserved : 0000 [03Eh 0062 2] Base Address Offset : 0016 [040h 0064 2] Address Size Offset : 0022 [042h 0066 12] Base Address Register : [Generic Address Structure] [042h 0066 1] Space ID : 00 [SystemMemory] [043h 0067 1] Bit Width : 00 [044h 0068 1] Bit Offset : 00 [045h 0069 1] Encoded Access Width : 03 [DWord Access:32] [046h 0070 8] Address : 00000000FE034000 [04Eh 0078 4] Address Size : 00001000 [052h 0082 15] Namepath : "\_SB.PCI0.UAR2" Change-Id: If34a3d2252896e0b0f762136760ab981afc12a2f Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/22453 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

2017-09-21soc/intel/skylake: Add config for enabling LTR for PCIe Root portRizwan Qureshi
There are a lot errors reported by AER driver for root port 0. The erors are being caused by an unsupported request from the device to the upstream port. Enabling LTR on the root port stops these errors, it is because LTR is enabled on the device side but not on the root port and hence root port was logging the LTR messages from the device as unsupported. The PCIe base spec (v3.1a) section 6.18 also states that: LTR support is discovered and enabled through reporting and control registers described in Chapter 7. Software must not enable LTR in an Endpoint unless the Root Complex and all intermediate Switches indicate support for LTR. Note that it is not required that all Endpoints support LTR to permit enabling LTR in those Endpoints that do support it. When enabling the LTR mechanism in a hierarchy, devices closest to the Root Port must be enabled first. If an LTR Message is received at a Downstream Port that does not support LTR or if LTR is not enabled, the Message must be treated as an Unsupported Request. FSP has a UPD for enabling/disabling LTR on root port, use the same for configuring LTR on PCIe root ports.

2017-09-20vboot: reset vbnv in cmos when cmos failure occursAaron Durbin
There's an occasional issue on machines which use CMOS for their vbnv storage. The machine that just powers up from complete G3 would have had their RTC rail not held up. The contents of vbnv in CMOS could pass the crc8 though the values could be bad. In order to fix this introduce two functions: 1. vbnv_init_cmos() 2. vbnv_cmos_failed() At the start of vboot the CMOS is queried for failure. If there is a failure indicated then the vbnv data is restored from flash backup or reset to known values when there is no flash backup.
