ad6157ebdf timestamps: Rename timestamps to make names more consistent
This patch aims to make timestamps more consistent in naming,
to follow one pattern. Until now there were many naming patterns:
- TS_START_*/TS_END_*
- TS_BEFORE_*/TS_AFTER_*
- TS_*_START/TS_*_END
This change also aims to indicate, that these timestamps can be used
to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

6724ba4f04 memory_info.h: Store SMBIOS error correction type
There are platforms that support error correction types other than
single-bit ECC. Extend meminfo to accomodate additional ECC types.

It is assumed that `struct memory_info` is packed to save space. Thus,
use `uint8_t` instead of an enum type (which are usually 4 bytes wide).

ad9cd687b8 mrc_cache: Add mrc_cache fetch functions to support non-x86 platforms
Create two new functions to fetch mrc_cache data (replacing
mrc_cache_get_current):

- mrc_cache_load_current: fetches the mrc_cache data and drops it into
  the given buffer.  This is useful for ARM platforms where the mmap
  operation is very expensive.

- mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a
  given buffer.  This is useful for platforms where the mmap operation
  is a no-op (like x86 platforms).  As the name mentions, we are not
  freeing the memory that we allocated with the mmap, so it is the
  caller's responsibility to do so.

Additionally, we are replacing mrc_cache_latest with
mrc_cache_get_latest_slot_info, which does not check the validity of
the data when retrieving the current mrc_cache slot.  This allows the
caller some flexibility in deciding where they want the mrc_cache data
stored (either in an mmaped region or at a given address).

BUG=b:150502246

d058131586 nb/intel/sandybridge/raminit: Add ECC debug code
* Add ECC test code when DEBUG_RAM_SETUP is enabled
* Move ECC scrubbing after set_scrambling_seed() to be able to observe
  what has been cleared in the test routine. If clearing happens
  before set_scrambling_seed the data is XORed with a different PRN.
  Data read from memory will look random instead of all zeros.
* ECC scrubbing must happen after dram_dimm_set_mapping()
  The ECC logic is set to "normal mode" in dram_dimm_set_mapping(). In
  normal mode the ECC bits are calculated and stored on write
  transactions.
* Move method out of try_init_dram_ddr3().
  This satisfies point 2 and point 3 of the list above.

42609d807b nb/intel/*: Fill in SMBIOS type 16 on SNB/HSW
Fill in the maximum DRAM capacity and slot count read from CAPID0_A
registers on Sandy Bridge and Haswell.

While the register isn't part of the Core Series datasheet, it can be
found in the corresponding "Intel Open Source Graphics Programmer's
Reference" datasheets.

Note that the values for DDRSZ (maximum allowed memory size per channel)
need to be halved when only one DIMM per channel is supported. On mobile
platforms, all but quad-core processors are subject to this restriction.

Tested on Lenovo X230:
On Linux, verify that `dmidecode -t 16` reports the actual maximum
capacity (16 GiB) instead of the currently-installed capacity (4 GiB) or
the max capacity assuming two DIMMs per channel is possible (32 GiB).

a6a64183d6 nb/intel/sandybridge: Void MRC cache if CPUID differs
Native raminit asserts that the DIMMs haven't been replaced before
reusing the saved training data. However, it does not check if the CPU
is still the same, so it can end up happily reusing data from an Ivy
Bridge CPU onto a Sandy Bridge CPU, which runs the raminit_ivy.c code
path. This can make the CPU run in unsupported configurations, which may
result in an unstable system, or a failure to boot.

To prevent that, ensure that the stored CPUID matches the CPUID of the
installed CPU. If they differ, print a message and do not use the saved
data. As it does not pose a problem for a regular boot, but precludes
resuming from S3, use different loglevels depending on the bootpath.

Tested on Asus P8Z77-V LX2 with an i7-2600 and an i5-3330, works well.

- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?

Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

8852188113 nb/intel/sandybridge: Add a bunch of MCHBAR defines
While we are at it, also:
- Rename related variables to match the register names.
- Update some comments to better reflect what some registers are about.
- Add various FIXME comments on registers that seem to be used wrongly.

With BUILD_TIMELESS=1, this commit does not change the coreboot build of:
- Asus P8H61-M PRO with native raminit.
- Gigabyte GA-H61MA-D3V with native raminit.
- Lenovo Thinkpad X230 with native raminit.
- Lenovo Thinkpad X220 with MRC raminit.

Also change some of the types to match the register widths
of the controller. It is expected that these prototypes
will be used with SMBus host controllers inside AMD chipsets
as well, thus the change of location.

This patch introduces 3 helper function for cpuid(1) :

1. cpu_get_cpuid() -> to get processor id (from cpuid.eax)
2. cpu_get_feature_flags_ecx -> to get processor feature flag (from cpuid.ecx)
3. cpu_get_feature_flags_edx -> to get processor feature flag (from cpuid.edx)

Above 3 helper functions are targeted to replace majority of cpuid(1)
references.
