Like Haswell, Broadwell has a "FSB" speed of 100 MHz. Add the IDs for
both the traditional and ULT variants of Broadwell, because the CPU
driver for Haswell already contains CPUIDs for both Broadwell types.
Without this patch, Broadwell CPUs would hang when trying to print the
first console log message, but only if flashconsole was not enabled.
This was missed in commit f542b7bcef (cpu/intel/haswell: Add Broadwell
CPUIDs and microcode) and went unnoticed until now because the tests
were done with flashconsole enabled, which somehow boots properly even
though the console time tracking would not work (depends on TSC).
Tested on out-of-tree Acer E5-573, fixes booting without flashconsole.

Starting with SPT, LPC registers IOD, IOE, LGIR* and LGMR need to be
mirrored to their corresponding DMI registers. Add the required writes
to DMI registers, where the PCI config registers get written.
This is already done in soc code for IOD, IOE and LGIR* by mirroring
the registers later, during PCH init. Also the code mostly matches
accross the platforms. This common implementation will avoid delayed
mirroring of the registers and also deduplicate the code.
This change also adds a new Kconfig that will be selected by platforms
requiring mirroring of LPC IO/MMIO registers to their corresponding DMI
registers.
For making use of this common code, the redundant soc code needs to be
dropped and the newly introduced Kconfig option has to be selected. This
is done in the follow-up change.

This patch adds explicit initializations for the remaining named display
(power) control GPIOs to the bootblock GPIO init code. These pins are
usually mapped to pins that are already configured to pull-downs on
power-on reset so this wasn't really required, but we have already moved
them around so often that you never know when EEs might one day move
them to a pin with a different power-on reset configuration, so it's
better to be explicit.
In one particular case, GPIO(67) (used by CoachZ rev1+ but not by
anything else for the EN_PP3300_DX_EDP pin) is not actually a pull-down
on boot, even though that is claimed by the datasheet. This is likely
due to the fact that it can serve as the SPI_HOLD pin for the boot flash
QSPI bus, so even though our board's boot flash doesn't really use that
pin, it seems that the boot ROM still configures it as such.

This change adds support for a common block memory driver that can be
used for performing the required operations to read SPD data for
different memory channel DIMMs. This data can then be used by the SoC
code to populate different memory related UPDs.
Most recent Intel platforms follow a similar pattern for configuring
FSP-M UPDs for initializing memory. These platforms use one of the
following topologies:
1. Memory down
2. DIMM modules
3. Mixed
Thus, SPD data is either obtained from CBFS (for memory down topology)
or from on-module EEPROM (for DIMM modules). This SPD data read from
CBFS or EEPROM is then passed into FSP-M using SPD UPDs for different
channels/DIMMs as per the memory organization.
Similarly, DQ/DQS configuration is accepted from mainboard and passed
into FSP-M using UPDs as per the FSP-M/MRC organization of memory
channels.
Different memory technologies on a platform support physical channels
of different widths. Since the data bus width is fixed for a platform,
the number of physical channels is determined by data bus width /
physical channel width. The number of physical channels are different
depending upon the size of physical channel supported by the memory
technology. FSP-M for a platform uses the same set of UPDs for
different memory technologies and aims at providing maximum
flexibility. Thus, the platform code needs to format mainboard inputs
for DQ, DQS and SPD into the UPDs appropriately as per the memory
technology used by the board.
Example: DDR4 on TGL supports 2 physical channels each 64-bit
wide. However, FSP-M UPDs assume channels 16-bit wide. Thus, FSP-M
provides 16 UPDs for SPDs (considering 2 DIMMs per channel and 8
channels with each channel 16-bit wide). Hence, for DDR4, only the SPD
UPDs for MRC channel 0 and 4 are supposed to be used.
This common driver allows the SoC to define the attributes of the
platform:
1. DIMMS_PER_CHANNEL: Maximum DIMMs that are supported per channel by
any memory technology on the platform
2. DATA_BUS_WIDTH: Width of the data bus.
3. MRC_CHANNEL_WIDTH: Width of the channel as used by the MRC to
define UPDs.
In addition to this, the SoC can define different attributes of each
memory technology supported by the platform using `struct
soc_mem_cfg`:
1. Number of physical channels
2. Physical channel to MRC channel mapping
3. Masks for memory down topologies
Using the above information about different memory technologies
supported by the platform and the mainboard configuration for SPD,
the common block memory driver reads SPD data and provides pointers to
this data for each dimm within each channel back to the SoC code. SoC
code can then use this information to configure FSP-M UPDs
accordingly. In addition to that, the common block driver also returns
information about how the channels are populated so that the SoC code
can use this information to expose DQ/DQS information in FSP-M UPDs.
This driver aims at minimizing the effort required for supporting
different memory technologies on any new Intel SoC by reducing per-SoC
effort to a table of configurations rather than having to implement
similar logic for each SoC.

Also switch to `bootblock_mainboard_early_init` to configure the pads in

In order to update the BB retimers for usb4/tbt they need to be turned
on and into TBT mode. Expand the current DSM to allow for the use of an
EC RAM byte RFWU to get the current state of each port and whether or
not it has a retimer. It also allows Kernel to issue state transitions
for the retimer to be put into TBT mode for firmware update.
BUG=b:162528867
TEST=Along with work in progress kernel and EC patches, the Retimer
firmware update is verified under device attached and no device attached
scenarios.

The PMC doesn't response any more due to invalid CNVi GPIO
configuration. This caused a 30 second boot delay in FSP-S.
Use the same values as FSP-S does. Always disable external I2S BT
audio and use NF3 for pad GPP_D5 and GPP_D6.
Tested on Prodrive hermes:
No boot delay can be observed any more.

For pq module size registers such as DISP_AAL_SIZE, the high bits
should be HSIZE, while low bits should be VSIZE. Fix the incorrect
settings for these registers where width and height are reversed.
According to MediaTek, there is no practical impact on mt8183 devices,
but it's still nice to get this fixed to avoid future confusion.

TSEG is located below TOLUD. The size is configured in ESMRAMC but can
also be configured with "-global mch.extended-tseg-mbytes=5" command
line argument. Note that the size in ESMRAMC needs to be 'invalid' (3)
for this to take action.
coreboot will leave TSEG at the default 1MiB.
Note that even if TSEG does not end up being used, it is likely a good
idea to not put anything there as if SMM gets locked down by something
else it will suddenly be inaccessible.

The old code was broken and register 0x90 didn't even exist any more in
the config space of the SMBus PCI device, so just always return the MMIO
base address of the SMBus controller. As far as I've seen, no board in
tree uses this functionality at the moment.

UART pad configuration should not be done in common code, because that
may cause short circuits, when the user sets a wrong UART index. Thus,
add the corresponding pads to a bootblock gpio table for the board as a
first step. Common UART pad config code then gets dropped in CB:48829.

Also switch to `bootblock_mainboard_early_init` to configure the pads in
early bootblock before console initialization, to make the console work
as early as possible. The board does not do any other gpio configuration
in bootblock, so this should not influence behaviour in a negative way
(e.g. breaking overrides).
