2018-12-28sb/intel/lynxpoint: Handle H81 only having 6 PCIe root portsTristan Corrick
The H81 chipset is the only non-LP Lynx Point chipset with 6 PCIe root ports, all others have 8 [1]. The existing PCIe code assumed that all non-LP chipsets had 8 root ports, which meant that port 6 would not be considered the last root port on H81, so `root_port_commit_config()` would not run. Ultimately, while PCIe still worked on H81, all the root ports would remain enabled, even if disabled in the devicetree. Also, remove `PCI_DEVICE_ID_INTEL_LYNXPOINT_MOB_DESK_{MIN,MAX}`, as they are unused, and the MAX constant is incorrect. Interestingly, this fixes an issue where GRUB is unable to halt the system. Tested on an ASRock H81M-HDS. The root ports disabled in the devicetree do indeed end up disabled.

2018-11-16sb/intel/lynxpoint: Generate the ACPI FADT with a common functionTristan Corrick
The function `acpi_fill_fadt()` is based on that of sb/intel/bd82x6x. Tested on an ASRock H81M-HDS and a Google Peppy board, both using Linux 4.9 with `acpi=strict`. No ACPI errors or warnings appear in the kernel log. System reset, poweroff, and S3 suspend/resume continue to work. General improvements -------------------- - `fadt->preferred_pm_profile` is set based on the value of `CONFIG_SYSTEM_TYPE_LAPTOP` instead of being hardcoded. - Constants are used instead of magic values in more locations. - `fadt->gpe0_blk`, `fadt->gpe0_blk_len`, and `fadt->x_gpe0_blk` are set appropriately depending on whether the system uses Lynx Point LP or not. - Boards can indicate docking support in the FADT via the devicetree. Changes to existing Lynx Point boards ------------------------------------- - `header->asl_compiler_revision` changes from 1 to 0. - `fadt->model` is left at 0 instead of being set to 1. This field is only needed for ACPI 1.0 compatibility. - `fadt->flush_size` and `fadt->flush_stride` are set to 0. This is because their values are ignored, since `ACPI_FADT_WBINVD` is set in `fadt->flags`. - `fadt->duty_offset` is set to 0 instead of 1. None of the existing boards indicate support for changing the processor duty cycle (as `fadt->duty_width` is set to 0), so `fadt->duty_offset` does not currently need to be set. - Access sizes of registers are set. - On mb/intel/baskingridge, the pmbase is now read using the common function `get_pmbase()` instead of `pci_read_config16(...)`. - On mb/intel/baskingridge, the value of `fadt->x_gpe0_blk.bit_width` changes from 64 to 128. The correct value should be 128 (bits), to match `fadt->gpe0_blk_len`, which is set to 16 (bytes). - On Lynx Point LP systems, the unused extended address `fadt->x_gpe0_blk` sets its address space ID to be consistent with other unused extended addresses. Such a change should not alter the interpretation of the registers as being unused. Why not set them all to zero? Simply because the existing practice, in both coreboot and some other vendors' firmware, has them set in such a case.

Pointer math with void pointers is illegal in many compilers, though it works with GCC because it assumes size of void to be 1. Change the pointers or add parenthesis to force a proper order that will not cause compile errors if compiled with a different compiler, and more importantly, don't have unsuspected side effects.
