2018-05-01nb/intel/x4x: Change memory layout to improve MTRRArthur Heymans
This change also makes sure that the sum the uma regions (TSEG, GSM, GSM) is 4MiB aligned. This is needed to avoid cbmem_top floating between 2 usable ram region, since cbmem_top is aligned 4MiB down to easy MTRR setup for ramstage. At least tianocore requires this and fails to boot without it. Better MTRR are achieved by making the memory 'hole' till 4GiB exactly 2Gib. This code mimics how it is done in nb/intel/gm45 and achieves similar results. TSEG is enabled and set to 8M since this makes it easier to reuse the common smm setup / parallel mp code and makes it possible to cache the ramstage in there like how it's done on newer targets. TESTED on Intel DG43GT.

2018-04-17nb/intel/x4x: Use SPI flash to cache raminit resultsArthur Heymans
Stores information obtained from decoding dimms and receive enable results for future use. Depreciates using rtc nvram to store receive enable settings. A notable change is that receive enable results are always reused, not just on a resume from S3. This requires cbmem to be initialized a bit earlier, right after the raminit finished to be able to add the sysinfo struct to cbmem which gets cached to the SPI flash in ramstage. TESTED on Intel DG43GT with W25Q128.V. With 4 ddr2 dimms time in raminit goes from 133,857ms (using i2c block read to fetch SPD) to 21,071ms for cached results.

2018-01-05nb/intel/x4x: Disable watchdog, halt TCO timer and clear timeoutArthur Heymans
Especially on ICH7 failing to do so results in i2c block read being unusable. On ICH10 this problem doesn't manifest itself that much. This moves disabling the watchdog reboot to the northbridge code like i945 (even though it technically is southbridge stuff). TESTED on Intel DG41WV: hacking on raminit is much nicer since no need to do a hard power down for +4s are needed to clear the timeouts.

2017-05-13nb/intel/x4x: Fix uninitialized variable issueNico Huber
A left-over from 5e3cb72a71 (nb/x4x: Do not enable IGD when not supported). Should fix coverity issue 1375009. Remove a redundant line that uses the variable `gfxsize` out of its scope and move the variable declaration. Make sure the variable is always initialized, drop unneeded error-handling for `get_option()` and sanitize the read value instead.

This would allow the P43 and P45 chipset variants to work.

It rewrites the results of receive enable stored in the upper nvram region, to avoid running receive enable again. Some debug info is also printed about the self-refresh registers. (Not enforcing a reset here, since 0 does not necessarily mean it's not in self-refresh).
