2013-11-25lynxpoint: Enable extra 16 IOAPIC entries for GPIO PIRQDuncan Laurie
LynxPoint-LP has an additional 16 entries in the IOAPIC that can be assigned to specific GPIOs when they are configured as PIRQ. The maximum redirection entries field in the IOAPIC needs to be set to 0x27 when this is enabled. Additionally specific GPIOs need to be routed to PIRQ so they interrupt via the IOAPIC instead of the GPIO IRQ 14/15.

2013-04-01lynxpoint: Move ACPI NVS into separate CBMEM tableDuncan Laurie
The ACPI NVS region was setup in place and there was a CBMEM table that pointed to it. In order to be able to use NVS earlier the CBMEM region is allocated for NVS itself during the LPC device init and the ACPI tables point to it in CBMEM. The current cbmem region is renamed to ACPI_GNVS_PTR to indicate that it is really a pointer to the GNVS and does not actually contain the GNVS.

2013-03-21haswell/lynxpoint: Use new PCH/PM helper functionsDuncan Laurie
This makes use of the new functions from pmutil.c that take care of the differences between -H and -LP chipsets. It also adds support for the LynxPoint-LP GPE0 register block and the SMI/SCI routing differences. The FADT is updated to report the new 256 byte GPE0 block on wtm2/wtm2 boards which is too big for the 64bit X_GPE0 address block so that part is zeroed to prevent IASL and the kernel from complaining about a mismatch. This was tested on WTM2. Unfortunately I am still unable to get an SCI delivered from the EC but I suspect that is due to a magic command needed to put the EC in ACPI mode. Instead I verified that all of the power management and GPIO registers were set to expected values. I also tested transitions into S3 and S5 from both the kernel and by pressing the power button at the developer mode screen and they all function as expected.

2013-03-21lynxpoint: Fix GPIO and PM base reservationsDuncan Laurie
The kernel ACPI was not happy with the Add inside a ResourceTemplate (or perhaps within the IO declaration) Instead make a buffer of IO reservations and turn _CRS into a method that updates the buffer depending on the chipset type. This adds an \ISLP() method that checks the chipset LPC device ID to see if it is -LP or -H. It also increases the PM base reservation to 256 bytes and moves both GPIO and PM base to above 0x1000 on -LP chipsets.

2013-03-14lynxpoint: lpc resource reservationsAaron Durbin
This commit updates the Lynx Point resource reservations before the coreboot allocator assigns resources. There is no need to mark anything as subtractive decode because there are no devices/buses linked to the LPC device. The I/O range reservations consists of claiming the first 4KiB of I/O space. The PMBASE, GPIOBASE, and LPC generic I/O decode ranges are checked against the default claimed range. If those ranges overlap or fall outside of the default range then those resources are added. The MMIO range reservations consist of claiming everything from the I/O APIC to 4GiB. The RCBA and the LPC Generic Memory range register are then conditionally added if they fall outside of the default MMIO range.

The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore, the southbridge support is included as well. The basis for this code is the Sandybridge code. Management Engine, IRQ routing, and ACPI still requires more attention, but this is a good starting point. This code partially gets up through the romstage just before training memory on a Haswell reference board.
