2018-10-24cpu/intel/smm: Don't make assumptions on TSEG_SIZEArthur Heymans
Do not assume: - TSEG is 8M - IED_REGION_SIZE is set (not needed on older platforms).

2018-10-08Move compiler.h to commonlibNico Huber
Its spreading copies got out of sync. And as it is not a standard header but used in commonlib code, it belongs into commonlib. While we are at it, always include it via GCC's `-include` switch. Some Windows and BSD quirk handling went into the util copies. We always guard from redefinitions now to prevent further issues.

2018-09-28src/*: normalize Google copyright headersPatrick Georgi
As per internal discussion, there's no "ChromiumOS Authors" that's meaningful outside the Chromium OS project, so change everything to the contemporary "Google LLC." While at it, also ensure consistency in the LLC variants (exactly one trailing period). "Google Inc" does not need to be touched, so leave them alone.

2018-07-30nb/intel/gm45: Use common code for SMM in TSEGArthur Heymans
This makes i82801ix use the common smm southbridge code to set up smm relocation and smi handler setup. This is needed in this change for the the smm relocation code relies on some southbridge functions provided in the common code. Some of the old code is kept for the Q35 qemu target. This also caches the TSEG region and therefore increases MTRR usage a little in some cases. Currently SMRR msr's are not set on model_1067x and model_6fx since this needs the MSRR enable bit and lock set in IA32_FEATURE_CONTROL. This will be handled properly in the subsequent parallel mp init patchset. Tested on Thinkpad X200: boots and going to and resuming from S3 still works fine.

2018-04-10cpu/intel/sandybridge: Put stage cache into TSEGArthur Heymans
TSEG is not accessible in ring 0 after it is locked in ramstage, in contrast with cbmem which remains accessible. Assuming SMM does not touch the cache this is a good region to cache stages. The code is mostly copied from src/cpu/intel/haswell. TESTED on Thinkpad X220: on a cold boot the stage cache gets created and on S3 the cached ramstage gets properly used.
