The 51nb X210 is a replacement motherboard for Thinkpad X200/X201 systems,
based on a modern Kabylake CPU. It also ships with no firmware protection,
(IFD is fully unlocked, no protected regions are set, no Bootguard),
making it an ideal coreboot target. This port is based on the support for
the Skylake-based Purism Librem 13v3, with the following significant
changes:
* EC firmware is contained within the system SPI flash, and so a blob of
EC firmware must be injected to a defined location during image build.
* GPIO layout is different - this is currently just a raw import of the
GPIO configuration from the vendor firmware
* The system has two DIMMs, so an additional SPD address has been added
* The USB port layout is different
* The EC must be enabled at boot time through SuperIO-style logical device
configuration
* EC register layout is different, necessitating changes in the ACPI tables
* The HDA pins are different
* The genx_dec config is different
All hardware appears to work as expected, although the SD reader is
untested.

Below changes are done:
1. Allow execution of HMRFPO_ENABLE command if CSE meets below
prerequisites:
- Current operation mode(COM) is Normal and Curret working state(CWS)
is Normal.
-(or) COM is Soft Temp Disable and CWS is Normal if ME's
Firmware SKU is Custom.
2. Check response status.
3. Add documentation for send_hmrfpo_enable_msg().
4. Rename padding field of hmrfpo_enable_resp to reserved.
The HMRFPO (Host ME Region Flash Protection Override) mode prevents CSE to
execute SPI I/O cycles to CSE region, and unlocks the CSE region to perform
updates to it. This command is only valid before EOP(End of Post).
For Custom SKU, follow below procedure to place CSE in HMRFPO mode:
1. Ensure CSE boots from BP1. When CSE boots from BP1, it will have
opmode Temp Disable Mode.
2. Send HMRFPO_ENABLE command to CSE. Then, CSE enters HMRFPO mode.
CSE Firmware Custom SKU Image Layout:
= [RO] + [RW + DATA PART] = [BP1] + [BP2 + DATA PART]
Here, BP1 will have reduced functionality of BP2, and the BP1 will be
CSE's RO partition and [BP2 + DATA PART] together will represent
CSE's RW partition. CSE can boot from either BP1(RO) or BP2(RW).
CSE Image Layout in Consumer SKU: BP2 + BP3 + DATA PART
TEST=Verfied on hatch board.

The code in coreboot is actually for the Arrandale processors, which
are a MCM (Multi-Chip Module) with two different dies:
- Hillel: 32nm Westmere dual-core CPU
- Ironlake: 45nm northbridge with integrated graphics
This has nothing to do with the older, single-die Nehalem processors.
Therefore, replace the references to Nehalem with the correct names.

The code is for Arrandale CPUs, whose System Agent is Ironlake.
This change simply replaces `nehalem` with `ironlake` and `NEHALEM`
with `IRONLAKE`. The remaining `Nehalem` cases are handled later, as
changing some of them would impact the resulting binary.
Tested with BUILD_TIMELESS=1 without adding the configuration options
into the binary, and packardbell/ms2290 does not change.

Volteer uses 4 bits (hardware straps) to indicate what memory
configuration the board is populated with (i.e. which SPD file
to use for the populated memory). This allows for only 16
different SPDs for supporting Volteer and all future variants of
Volteer. Currently, each memory chip needs its own SPD file, so we
can only support 16 different memory chip options for Volteer and
all of its variants.
Generic SPD files are just SPD files that have been stripped down
to contain only fields that are important for the memory controller
(strips out items like vendor info, for example). Using generic SPD
files allows for more than 16 different memory options given it's no
longer a 1-to-1 mapping as similar memory modules from different
vendors can share the same generic SPD file.

Set value for PcieRpL1Substates according to devicetree.
Chip config parameter PcieRpL1Substates uses (UPD value + 1)
because UPD value of 0 for PcieRpL1Substates means disabled for FSP.
In order to ensure that mainboard setting does not disable L1 substates
incorrectly, chip config parameter values are offset by 1 with 0 meaning
use FSP UPD default.
get_l1_substate_control() ensures that the right UPD value is set in
fsp_params.
Chip config parameter values
0: Use FSP UPD default
1: Disable L1 substates
2: Use L1.1
3: Use L1.2 (FSP UPD default)
