The tXP bitfield is 3 bits wide, and the tXPDLL bitfield is 5 bits wide.
Clamp any values that would overflow this field. Bits in TC_DTP already
get set when the tXP and/or tXPDLL values are large.

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).

Command timing is the absolute value of the most negative `pi_coding`
value across all ranks, or zero if there are no negative values. Use the
MAX() macro to ease proving that `cmd_delay` can never be negative, and
then drop the always-false underflow check.
The variable type for `cmd_delay` still needs to be signed because of
the comparisons with `pi_coding`, which is a signed value. Using an
unsigned type would result in undefined and also undesired behavior.

Clock is a differential signal and propagates faster than command and
control, therefore its timing needs to be offset with `pi_code_offset`.
It is also a periodic signal, so it can safely wrap around.
To avoid potential undefined behavior, make `clk_delay` signed. It makes
no difference with valid values, because the initial value can be proven
to never be negative and `pi_code_offset` is always positive. With this
change, it is possible to add an underflow check, for additional sanity.

To allow adjusting the phase shift of the various I/O signals, the
memory controller contains several PIs (Phase Interpolators). These
devices subdivide a QCLK (quarter of a clock cycle) in 64 `ticks`,
and the desired phase shift is specified in a register. For shifts
larger than one QCLK, there are `logic delay` registers, which allow
shifting a whole number of QCLKs in addition to the PI phase shift.
The number of PI ticks in a QCLK is often used in raminit calculations.
Define the `QCLK_PI` macro and use it in place of magic numbers. In
addition, add macros for other commonly-used values that use `QCLK_PI`
to avoid unnecessarily repeating `2 * QCLK_PI`, such as `CCC_MAX_PI`.

Most ofte, `iosav_run_once` precedes a `wait_for_iosav` call. Add a

Do not combine the host bridge device ID with the CPU stepping because
it is confusing. Although Sandy/Ivy Bridge processors incorporate both
CPU and northbridge components into the same die, it is best to treat
them separately. Plus, this change enables moving CPU stepping macros
from northbridge code into the CPU scope, which is done in a follow-up.

Commit 7f1363d9b4 (nb/intel/sandybridge: Program MR2 shadow register)
has a bug where the system locks up and power cycles when booting Linux,
but is still able to pass memtest86+ with flying colors. The issue will
occur when the following conditions are true:
- CPU is Ivy Bridge
- Memory speed is not greater than 1066 MHz (DDR3-2133 or slower)
- System contains dual-rank DIMMs
- The second rank of the dual-rank DIMMs is mirrored
- All DIMMs support Extended Temperature Range
- At least one of the DIMMs does not support Auto Self-Refresh
If all of these conditions are met, the final value of the MR2 Shadow
registers configures the memory controller to issue a MRS command to
update MR2 before entering self-refresh mode, but indicates that rank
mirroring is not required (the first rank on a DIMM is never mirrored).
Before the memory controller enters self-refresh, it sends MRS commands
to all ranks to update MR2, but the missing address and bank mirroring
means DRAM chips on mirrored ranks instead clobber MR1 with junk data.
With garbage in MR1, the mirrored ranks no longer function properly,
which ultimately leads to all hell breaking loose (undefined behavior).
The condition is backwards, since only odd ranks can be mirrored. To
avoid this problem completely, simply remove the condition. The final
register value will still be correct, since the bits are always ORed.
Tested on Asus P8Z77-V LX2, fixes booting Linux with dual-rank DIMMs.

This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file()
to cbfs_map() and cbfs_load() respectively. This is supposed to be the
start of a new, better organized CBFS API where the most common
operations have the most simple and straight-forward names. Less
commonly used variants of these operations (e.g. cbfs_ro_load() or
cbfs_region_load()) can be introduced later. It seems unnecessary to
keep carrying around "boot" in the names of most CBFS APIs if the vast
majority of accesses go to the boot CBFS (instead, more unusual
operations should have longer names that describe how they diverge from
the common ones).
cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly
reap mappings when desired. A few new cbfs_unmap() calls are added to
generic code where it makes sense, but it seems unnecessary to introduce
this everywhere in platform or architecture specific code where the boot
medium is known to be memory-mapped anyway. In fact, even for
non-memory-mapped platforms, sometimes leaking a mapping to the CBFS
cache is a much cleaner solution than jumping through hoops to provide
some other storage for some long-lived file object, and it shouldn't be
outright forbidden when it makes sense.
Additionally, remove the type arguments from these function signatures.
The goal is to eventually remove type arguments for lookup from the
whole CBFS API. Filenames already uniquely identify CBFS files. The type
field is just informational, and there should be APIs to allow callers
to check it when desired, but it's not clear what we gain from forcing
this as a parameter into every single CBFS access when the vast majority
of the time it provides no additional value and is just clutter.

In order to run a write leveling test, one needs to unset the Qoff bit
in MR1, then run the test, and finally set Qoff again. The current IOSAV
sequence uses two subsequences to perform the test, while the other two
are unused. It is possible to perform the two necessary MR1 updates in
the same sequence, which can potentially improve runtime (not measured).
Since `write_mrreg` is no longer used, it is necessary to handle address
mirroring explicitly. This can be accomplished with the recently-added
`ddr3_mirror_mrreg` function, which is also used in `write_mrreg`.

Write training needs to update mode register 1, but `write_mrreg` will
clobber the IOSAV sequence. Reference code uses one four-subsequence to
unset Qoff in MR1, run the test, and finally set Qoff again. This will
be implemented in future changes, and will use the newly-added helper.

The intent here is to clear the register, so a simple write will work.

There's no need to use `struct timA_minmax`, since most cases only care
about the difference between logic delay deltas. The final step does use
the minimum logic delay across all lanes, but it's a special case.

This register must be programmed if Self-Refresh Temperature range is
enabled in MR2 (bit 7). Because the memory controller needs to reprogram
MR2 when entering Self-Refresh, it needs a copy of the MR2 settings. It
also needs to know about mirrored ranks to correctly issue MRS commands.
