This patch fixes a bug in the software_i2c (bitbang) framework where it
would previously not return an error when receiving a NACK on a write
transaction (deviating behavior from our hardware I2C drivers). It also
adds explicit error codes to be returned for the different kinds of
failure conditions so they are more useful for debugging when dumped.

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.

This training find the optimal write DQ delay and read DQS delay
settings. It does so on all lanes at the same time, like
vendor (training each lane individually has poor results).
The results are stored in the sysinfo struct and restored on next
boots and S3 resume.
This potentially increases stability as optimal settings are chosen
and is more necessary for DDR3 raminit where the write DQS delays are
leveled/variable due to the flyby topology.
TESTED on Intel DG43GT with (2G + 1G) on each channel, see that the
results are quite close to the safe original ones (that previous
worked fine) and tested with memtest86+.

Remove locking of PCI device 00:00.0 registers (nehalem/finalize.c)
and remove setting the zeroth bit of the MSR_LT_LOCK_MEMORY = 0x2e7 MSR
register (model_2065x/finalize.c) to fix a frozen boot and S3 resume issue
which became apparent with commit d533b16669.
More detailed, either setting the LSB of the 32 bit register at 0x98
of the PCI device 00:00.0 (in the intel_nehalem_finalize_smm function) or
setting the LSB of the the MSR register MSR_LT_LOCK_MEMORY = 0x2e7 (in the
intel_model_2065x_finalize_smm function) indepentenly causes a freeze
during bootup or a complete session loss on resuming from S3 as described
here: https://mail.coreboot.org/pipermail/coreboot/2018-April/086564.html
It seems like Nehalem CPUs do not have a MSR_LT_LOCK_MEMORY register.
Additionally, the "Intel Core i7-600, i5-500, i5-400 and i3-300 Mobile
Processor Series, Datasheet Volume Two" indicates that registers of the
PCI device 00:00.0 cannot be locked manually. Instead, they can only be
locked by TXT, VT-d, CMD.LOCK.MEMCONFIG, ME_SM_LOCK or D_LCK.
Finally, the addresses and sizes of these registers were partially wrong.
Tested on Lenovo X201i with a Core i3 330M (no AES-NI, no VT-d and no TXT
support compared to the Core i5 and Core i7 processors of a X201).

Currently the thermal event handler method TEVT is defined as an extern,
then defined again in platforms with thermal event handling. In newer
versions of IASL, this generates an error, as the method is defined in
two places. Simply removing the extern causes the call to it to fail on
platforms where it isn't actually defined, so add a preprocessor define
where it's implemented, and only call the method on those platforms.

Currently, google_chromeec_pd_get_amode infinitely loops if a TCPC port
is connected to a device with alternate mode(s) and the call is made
for the mode with the index higher than 0 (e.g. Zinger).
Cros EC manages alternative modes entered in an array (amode[]). The
command is designed to accept a query for an particular index and a
particular SVID.
Zinger has a 'Google' mode. It's stored in amode[0]. When AP queries
first time for DisplayPort with index=0, EC says 'no' as expected.
AP sends the next query with index=1 but EC_CMD_PROTO_VERSION (0x00)
is sent instead because cmd_code is cleared by google_chromeec_command.
res.svid is supposed to be 0 when EC hits the last index + 1 but
res.svid is set to 2 by the EC_CMD_PROTO_VERSION handler because
EC_PROTO_VERSION is currently 2. So, the call succeeds and AP goes to
the next index and this repeats forever.
Any USB-C device with non-DisplayPort alternate mode can cause this
hang unless HDMI port is used.
This patch resets all the fields of chromeec_command in each iteration
in case google_chromeec_command changes them.

All ARM architecture boards are supposed to have a TTB region for their
page tables. ARM systems cannot use the data cache without enabling
paging, so it is imperative to do that as soon as possible. They will
also fault on unaligned accesses when not using the cache, which breaks
assumptions in CBFS code.
Unfortunately, we have some old boards in various stages of disrepair in
the tree that don't always follow these sorts of standard conventions.
It's not clear whether they actually boot anymore and if anyone still
has the respective hardware available to maintain them. I cannot really
fix and test them right now, but we should at least create a fake TTB
section for them so that common architecture code may make the correct
assumptions about which regions exist.
