2013-12-18lynxpoint: Don't write to non-existent EHCIDuncan Laurie
The LynxPoint-LP chipset only has one EHCI controller so we should not attempt to write into the second one that only exists on LynxPoint-H.

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.

2013-03-18lynxpoint: Move a bit of generic RCBA into early_pchDuncan Laurie
Rather than have to repeat this bit in every mainboard. Also, remove the reset of the RTC power status from here. We had done this in TOT for current platforms but did not carry it back to emeraldlake2 where this branched from. If we clear the status here then we don't get an event logged later which can be important for the devices that do not have a CMOS battery.

2013-03-17haswell platforms: restructure romstage mainAaron Durbin
There was a mix of setup code sprinkled across the various components: southbridge code in the northbridge, etc. This commit reorganizes the code so that northbridge code doesn't initialize southbridge components. Additionally, the calling dram initialization no longer calls out to ME code. The main() function in the mainboard calls the necessary ME functions before and after dram initialization. The biggest change is the addition of an early_pch_init() function which initializes the BARs, GPIOs, and RCBA configuration. It is also responsible for reporting back to the caller if the board is being woken up from S3. The one sequence difference is that the RCBA config is performed before claling the reference code. Lastly the rcba configuration was changed to be table driven so that different board/configurations can use the same code. It should be possible to have board/configuration specific gpio and rcba configuration while reusing the romstage code.
