2013-11-25lynxpoint: Enable USB clock gating, late setup, and sleep prepDuncan Laurie
Both EHCI and XHCI controllers have additional setup steps that are not part of the PEI reference code so they need to be done later. Both controllers also have specific clock gating setup requirements that are now implemented. Additionally they both have specific requirements when entering sleep states. XHCI needs something in S3/S4/S5 and EHCI only has steps for S4/S5 entry.

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

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.

2013-03-18haswell: Use SMM ModulesAaron Durbin
This commit adds support for using the SMM modules for haswell-based boards. The SMI handling was also refactored to put the relocation handler and permanent SMM handler loading in the cpu directory. All tseg adjustment support is dropped by relying on the SMM module support to perform the necessary relocations.

Now that MMCONF_SUPPORT_DEFAULT is enabled by default remove the pcie explicit accesses. The default config accesses use MMIO.

2013-03-14haswell: Add initial support for Haswell platformsAaron Durbin
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.
