Make sure to match devices on the root bus only. This fixes an issue where the SoC returned "MCHC" as ACPI name for devices behind bridge devices, as the DEVFN matched. Fixes observed "ACPI exception: AE_NOT_FOUND" in dmesg, as the ACPI path no longer contains invalid names. Tested on Supermicro X11SSH-TF.

2019-09-03soc/skylake: do not rely on P2SB data to generate DRHDAngel Pons
The P2SB PCI device can be "hidden", which causes all sorts of nightmares and bugs. Moreover, FSP tends to hide it, so finding a good solution to this problem is impossible with FSP into the mix. Since the values for IBDF and HBDF were already hardcoded as FSP parameters, define them as macros and use these values directly to generate the DRHD.

2019-08-20src: Remove variable length arraysJacob Garber
Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].

To support generating USB devices in ACPI the platform needs to know how to determine a device name for each USB port, and for any root hubs that may be present. Recent Intel platforms route all ports to an XHCI controller through a root hub. This is supported by considering the root hub to be USB port type 0, the USB 2.0 ports to be type 2, and the USB 3.0 ports to be type 3. This was tested with a Kaby Lake platform by adding entries to the devicetree and checking the resulting SSDT.

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>

2017-04-28intel/skylake: Switch FADT to ACPI version 3.0Werner Zeh
On Apollo Lake it was discovered that our current FADT implementation is valid for ACPI version 3.0 but misses fields for ACPI version 5.0. We run into booting issues with Windows 10 using version 5 in the FADT header. In commit 2b8552f49bc3a7d0290f96a84b573669de396011 (intel/apollolake: Switch FADT to ACPI version 3.0) we go back to version 3 for Apollo Lake.

2017-04-13soc/intel/skylake: Split AC/DC settings for Deep Sx configDuncan Laurie
Currently when enabling Deep S3 or Deep S5 it unconditionally gets enabled in both DC and AC states. However since using Deep S3 disables some expected features like wake-on-USB it is not always desired to enable the same state in both modes. To address this split the setting and add a separate config for Deep Sx in AC and DC states. All motherboards that set this config were updated, but there is no actual change in behavior in this commit. BUG=b:36723679 BRANCH=none TEST=This commit has no runtime visible changes, I verified on Eve that the Deep SX config registers are unchanged, and it compiles for all affected boards.

2017-02-14intel/skylake: Disable FADT.8042 if NO_FADT_8042 is setJenny TC
Kernel relies on FADT 8042 flag to enable/disable 8042 interface. If FADT reports 8042 capability and 8042 (/PS2) capability is actually disabled by coreboot, kernel would assume the presence of 8042 based on the FADT flag. This results in undesired system power off when kernel tries to access the 8042 memory region. To address this, CONFIG_NO_FADT_8042 was added to selectively disable 8042 on FADT.
