X2F-N100 is an embedded device/firewall with Intel N100 SoC and
4x 2.5Gb Intel I226-V NICs.
Currently tested and working:
- Payload (EDK2)
- Suspend (S3 state)
- All USB ports
- 4x NICs
- M.2 NVME
- mPCI-E (WiFi/modem)
- 4G USB modem in mPCI-E slot
- PCI-E passtrough to VMs (NICs)
- HDMI/DP output + HDA audio
OS:
- Alpine Linux
- Windows 11 Pro (from USB)
Untested, looks sane:
- Internal USB port on M.2 slot marked as "5G_USB"
Broken/TODO:
- SATA EDK2 reports "Unsupported", drive's not detected.
- Suspend in Windows (statements dreamed up by the utterly deranged)

Found on tiny firewall appliance from Chinese company named "Topton"
with Intel N100 SoC. This system is fanless so all we need is the
ability to use serial output (RS232 in RJ45 form-factor, called
"Cisco-style" at address 0x3f8), which is working.

This brings the old raminit implementation for CX700 back. It was
removed in commit e99f0390b9b8 (Remove VIA CX700 northbridge sup-
port). The code is mostly unchanged, three minor issues are fixed:
* A shift (>>= 2) was missing when reading tRRD from SPD byte 28.
The fixed value matches what the vendor BIOS of a VIA EPIA-EX
board programs. The code also suggests that we are looking for
a small value (<= 19 for DDR2-533).
* We allow the board port to specify which clock outputs should
be enabled now. This is necessary for the VIA EPIA-EX, which
needs the ALL_MCLKO setting (instead of the previously hard-
coded MCLKO2.
* When programming the DQS output delays, we considered the 1~2
rank values only for single-rank configurations. Changing the
`< 2` to `<= 2` brings us closer to the vendor values on the
VIA EPIA-EX.
Otherwise a lot of cosmetics changed. Partly because the original
code was to be #included into another C file, but also to satisfy
checkpatch. Also, all the #if'd code was removed (32-bit width
option, ECC, etc.).

This northbridge provides a lot of knobs for fine-grained tuning of the
FSB drivers. The programming manual calls this "Host AGTL+ I/O Driving
Control". We program the known good values for use with a VIA C7 CPU,
and warn about use with different CPUs.
The numbers were pulled out of raminit of the original CX700 port.
Originally, there was a write to 0x83 as well, to set bit 1 which
triggers a soft reset of the CPU. It was amidst a table, so it
seems unclear if it was put there intentionally.

The current design has the emit_wifi_sar_acpi_structures() function
load and unload the SAR binary. Since DSM and Bluetooth SAR data
structures are used outside this function, they are being copied into
data structure located in the calling function stack. This overhead is
unnecessary as loading and unloading the SAR binary could be done by
the calling function.
In addition, we are about to add several Bluetooth related data
structures which, under the current design, would require to add even
more data structure copy operations.

GPE route for GPE0_DW0 was not being programmed (i.e. 0) which made it
route to GPP_B since a value of 0 means GPP_B. GPE route for GPE0_DW1
is also being programmed to GPP_B which makes the overall configuration
invalid.
The fix is to program the GPE0_DW0 route to a GPIO group which is not
already being used for GPE0_DW1 & GPE0_DW2 i.e. GPP_A.
Additionally, the common GPE route configuration is moved to baseboard.

This patch refactors the configuration of GPP_E07 (EC_SOC_INT_ODL) to

Specifically, GPP_E07 is not connected (NC) on google/fatcat boards
with the Microchip EC AIC. However, it is required for google/fatcat
boards with Nuvoton/ITE AICs.

The current WWAN(LTE) does not require any sar setting from RF team's
suggestion, and sar sensor will be removed from DVT schematic.
To reserve the extendibility, add the fw_config DB_1A_LTE_SAR:
field DB_USB 11 12
option DB_1A 0 (None LTE)
option DB_1A_LTE 1 (LTE without sar sensor)
option DB_1A_LTE_SAR 2 (LTE with sar sensor)
end
Base on the fw_config to enable/disable related functions:
0)Disable WWAN and Sar if DB_USB = DB_1A
1)Enable WWAN and disable sar sensor if DB_USB = DB_1A_LTE
2)Enable WWAN and Sar sensor if DB_USB = DB_1A_LTE_SAR

This patch updates the eSOL rendering logic to use the
SOC_INTEL_CSE_LITE_SYNC_IN_RAMSTAGE config option instead of
SOC_INTEL_CSE_LITE_SKU.
The SOC_INTEL_CSE_LITE_SKU config option was incorrectly used to
determine whether to render eSOL during ramstage.
The SOC_INTEL_CSE_LITE_SYNC_IN_RAMSTAGE config option specifically
indicates whether CSE synchronization is performed during ramstage,
making it a more appropriate choice for this purpose.
This change ensures that eSOL is rendered correctly during ramstage on
platforms that require CSE synchronization.

Add basic support for the Serial Flash Discoverable Parameters (SFDP)
standard which can be used to discover the parameters to interact with
any SPI flash chip that supports this mechanism. This commit adds
functionality to find specific SFDP parameter headers and print all SFDP
parameter headers, but not to parse any SFDP parameter table. This is a
preparation for a follow-up patch that adds support to parse the RPMC
SFDP parameter table. Since 'find_sfdp_parameter_header' is only used in
the next patch, it's marked as static inline in this commit so that the
code still build; the 'inline' keyword will be removed again in that
follow-up patch.
For now, only the legacy access protocol using single bit SPI transfers
is supported, but this should cover most of the SPI NOR flash chips. In
any other case, the code will error out. It's also assumed that the SFDP
data blocks read from the SPI flash chip are small enough to fit into
the SPI host controller buffer and don't need to be broken up into
multiple transfers. This limitation will be addressed in a follow-up
patch.
JESD216F.02 was used as a reference.
TEST=On a board with a W74M12JW SPI flash chip, calling
'spi_flash_print_sfdp_headers' prints this on the console output:

This patch optimizes the reset handling in the Alder Lake romstage while
disabling the UFS controller in an uni-boot scenario (a unified AP
firmware image can boot both UFS and non-UFS systems).
It introduces a check in `mainboard_expects_another_reset()` to skip
unnecessary resets when a CSE slot switch is due, meaning CSE is not
booting from the RW slot. This saves one reset for non-UFS SKUs when
a CSE slot switch is pending.
The patch also relocates the `cse_fw_sync()` call after disabling the
UFS controllers to ensure the system reset flow can be better optimized
and combined with any expected resets due to CSE synchronization.
TEST=Able to build google/trulo eMMC sku and able to save one reset.
Without this patch:
1. Warm reset after disabling UFS (1st reset)
2. Global reset after CSE sync (2nd reset)
3. Warm reset after disabling UFS (3rd reset)
4. Boot to OS
With this patch:
1. Skip disabling UFS if CSE sync is due, aka no reset.
2. Global reset after CSE sync (1st reset)
3. CSE is booting from slot RW meaning CSE sync is done, perform UFS
disabling and issue a warm reset after disabling UFS (2nd reset)
4. Boot to OS

Before entering FSP-M, AP firmware must ensure the PM1_CNT register
reflects the correct sleep state if a global reset occurred.
This is crucial when Intel CSE has reset the system, as indicated by
the global reset bit and wake status register.
If PM1_CNT doesn't contain a valid sleep state after a CSE reset, AP
firmware must enforce an S5 exit path before handing control to FSP-M
for CSE initialization. This ensures proper system initialization and
avoids potential issues caused by an inconsistent sleep state.
Additionally, clears the PM1 status register (PM1_STS) after retrieving
the power state. This prevents stale status information from persisting
across power cycles, which could lead to confusion during subsequent
boots.
BUG=b:265939425
TEST=Verified that `prev_sleep_state` holds the correct value
(5 for S5) after CSE performs a global reset.
Fixes: Inconsistent sleep state after CSE reset.
