Drop the old, redundant code for mirroring LPC registers to DMI and make
use of the new common code.
Select the new Kconfig option for LPC DMI mirroring by the option
SOC_INTEL_COMMON_PCH_BASE, which is selected by platforms starting with
SPT, except APL and Xeon-SP. For Xeon-SP, select DMI and the new Kconfig
directly.
APL, even though it's younger than SPT, does not need mirroring.
Test: Set LGMR address by calling `lpc_open_mmio_window` and check that
both the PCI cfg and DMI LGMR register get written correctly.
Tested successfully on clevo/cml-u.

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 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.

The code for setting the LPC generic memory range uses an array of fixed
address ranges not needing explicit decoding, to decide if the address
needs to be written to the LGMR register. Most platforms only mistakenly
add the PCH reserved mmio range, that is not decoded generally,
effectively breaking the mechanism. Only APL uses the array correctly.
That code, in it's current state, does not work (except for APL) and
currently, there is not a single user. Thus, drop it before people start
using it.

In case of CPU PCIe RPs, the RP numbers might not be contiguous for
all the functions in a slot.
Example: In ADL, RP1 is 00:06.0, RP2 is 00:01.0 and RP3 is 00:06.2 as
per the FSP expectations.
Hence, this change updates the defintion of `struct pcie_rp_group` to
include a `start` member which indicates the starting PCI function
number within the group. All common functions for PCIe RP are
accordingly updated to take the `start` member into account.
Thus, in the above example, ADL can provide a cpu_rp_table as follows:
{
{ .slot = PCIE_SLOT_6, .start = 0, .count = 1 },
{ .slot = PCIE_SLOT_1, .start = 0, .count = 1 },
{ .slot = PCIE_SLOT_6, .start = 2, .count = 1 },
}
Since start defaults to 0 when uninitialized, current PCH RP group
tables don't need to be updated.

Add support for the Intel LPIT table to support reading Low Power Idle
Residency counters by the OS. On platforms supporting S0ix sleep states
there can be two types of residencies:
* CPU package PC10 residency counter (read from MSR via FFH interface)
* PCH SLP_S0 assertion residency counter (read via memory mapped
interface)
With presence of one or both of these counters in the LPIT table, Linux
dynamically adds the corresponding attributes to the cpuidle sysfs
interface, that can be used to read the residency timers:
* /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
* /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us
The code in src/acpi implements generic LPIT support. Each SoC or
platform has to implement `acpi_fill_lpit` to fill the table with
platform-specific LPI state entries. This is done in this change for
soc/intel/common, while being added as its own compilation unit, so SoCs
not yet using common acpi code (like Skylake) can use it, too.
Reference:
https://uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf

This change updates various uart_* functions to use simple(_s_)

* __SIMPLE_DEVICE__ check can be dropped since the same data type can
be used in early stages and ramstage.
* Removes the requirement on early stage to walk the device tree to

tree optimizations for early stages.
As part of this change, uart_get_device() is refactored and a new

in MMCONF format. It is then used directly by the _s_ variants of PCI
functions.

This change drops the parameter `struct device *dev` from the function
`soc_get_gen_io_dec_range()`. This function uses the parameter dev to
get a pointer to config structure for extracting the decode ranges
configured by mainboard in device tree. However, there is no separate
chip driver for the LPC device which means that the SoC code can use
`config_of_soc()` to get to SoC chip config instead of using the LPC
device.
This change is being done in preparation to clean up the device
tree/chip config access in early stages that allows for optimizing
the inclusion of device tree elements in the early stages.

For arch/x86 the realmode part has to be located within the same 64
KiB as the reset vector. Some older intel platforms also require 4 KiB
alignment for _start16bit.
To enforce the above, and to separate required parts of .text without
matching *(.text.*) rules in linker scripts, tag the pre-C environment
assembly code with section .init directive.
Description of .init section for ELF:
This section holds executable instructions that contribute to the
process initialization code. When a program starts to run, the
system arranges to execute the code in this section before calling the
main program entry point (called main for C programs).

Current implementation uses CPUID 0Bh function that returns the number
of logical cores of requested level. The problem with this approach is
that this value doesn't change when HyperThreading is disabled (it's in
the Intel docs), so it breaks generate_cpu_entries() because `numcpus`
ends up being zero due to integer division truncation.
- Use MSR 0x35 instead, which returns the correct number of logical
processors with and without HT.
- Use cpu_read_topology() to gather the required information
Tested on Prodrive Hermes, the ACPI code is now generated even with
HyperThreading disabled.

Currently it's not possible to add multiple graphics drivers into
one coreboot image. This patch series will fix this issue by providing
a single API that multiple graphics drivers can use.
This is required for platforms that have two graphic cards, but
different graphic drivers, like Intel+Aspeed on server platforms or
Intel+Nvidia on consumer notebooks.
The goal is to remove duplicated fill_fb_framebuffer(), the advertisment
of multiple independent framebuffers in coreboot tables, and better
runtime/build time graphic configuration options.
Replace all duplications of fill_fb_framebuffer and provide a single one
in edid_fill_fb.c. Should not change the current behaviour as still only
one graphic driver can be active at time.

Note that this would have the reverse problem if there is ever a non-common

This change enables caching for extended BIOS region.
Currently, caching is enabled for the standard BIOS region
upto a maximum of 16MiB using fast_spi_cache_bios_region,
used the same function to add the support for caching for
extended BIOS region as well.
Changes include:
1. Add a new helper function fast_spi_cache_ext_bios_window()
which calls fast_spi_ext_bios_cache_range() which calls
fast_spi_get_ext_bios_window() to get details about the
extended BIOS window from the boot media map and checks for
allignment and set mtrr.
2. Make a call to fast_spi_cache_ext_bios_region() from
fast_spi_cache_bios_region ().
3. Add new helper function fast_spi_cache_ext_bios_postcar()
which does caching ext BIOS region in postcar similar to 1.
4. If the extended window is used, then it enables caching
for this window similar to how it is done for the standard
window.

This change enables support for configuration of extended BIOS
region decode window. This configuration needs to be performed
as early as possible in the boot flow. This is required to
ensure that any access to the SPI flash region below 16MiB in
coreboot is decoded correctly. The configuration for the extended
BIOS window if required is done as part of fast_spi_early_init().
Changes include:
1. Make a call to fast_spi_enable_ext_bios() before the bus master
and memory space is enabled for the fast SPI controller.
2. Added a helper function fast_spi_enable_ext_bios() which calls
fast_spi_get_ext_bios_window() to get details about the extended
BIOS window from the boot media map.
3. Depending upon the SPI flash device used by the mainboard and
the size of the BIOS region in the flashmap, this function will
have to perform this additional configuration only if the BIOS
region is greater than 16MiB
4. Adddditionally, set up the general purpose memory range
registers in DMI.

This driver provides the following functionality:
1. Add a helper function dmi_enable_gpmr which takes as input base,
limit and destination ID to configure in general purpose memory range
registers and then set the GPMR registers in the next available
free GMPR and enable the decoding.
2. Add helper function get_available_gpmr which returns available free
GPMR.
3. This helper function can be utilized by the fast SPI driver to
configure the window for the extended BIOS region.

This change adds details about the memory map windows to translate
addresses between SPI flash space and host address space to coreboot
tables. This is useful for payloads to setup the translation using the
decode windows already known to coreboot. Until now, there was a
single decode window at the top of 4G used by all x86
platforms. However, going forward, platforms might support more decode
windows and hence in order to avoid duplication in payloads this
information is filled in coreboot tables.
`lb_spi_flash()` is updated to fill in the details about these windows
by making a call to `spi_flash_get_mmap_windows()` which is
implemented by the driver providing the boot media mapping device.

This change enables support for a custom boot media device in fast SPI
controller driver if the platform supports additional decode window
for mapping BIOS regions greater than 16MiB. Following new Kconfigs
are added:
1. FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW: SoC can select this to indicate
support for extended BIOS window.
2. EXT_BIOS_WIN_BASE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is
selected, this provides the base address of the host space that is
reserved for mapping the extended window.
3. EXT_BIOS_WIN_SIZE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is
selected, this provides the size of the host space reserved for
mapping extended window.
If platform indicates support for extended BIOS decode window,
cbfstool add command is provided additional parameters for the decode
window using --ext-win-base and --ext-win-size.
It is the responsibility of the mainboard fmap author to ensure that
the sections in the BIOS region do not cross 16MiB boundary as the
host space windows are not contiguous. This change adds a build time
check to ensure no sections in FMAP cross the 16MiB boundary.
Even though the platform supports extended window, it depends upon the
size of BIOS region (which in turn depends on SPI flash size) whether
and how much of the additional window is utilized at runtime. This
change also provides helper functions for rest of the coreboot
components to query how much of the extended window is actually
utilized.

Probabilistic interrupt storm is observed while kernel is configuring
the GPIO for SD card CD pin. The root cause is that the macro
PAD_CFG_GPI_GPIO_DRIVER isn't configuring trigger as PAD_TRIG(OFF).
The way GPIO interrupts are handled is:
1. Pad is configured as input in coreboot.
2. Pad IRQ information is passed in ACPI tables to kernel.
3. Kernel configures the required pad trigger.
Therefore, PAD_TRIG(OFF) should be added in PAD_CFG_GPI_GPIO_DRIVER
to turn off the trigger while pad is configured as input in coreboot
and then let kernel to configure the required pad trigger.

The patch modifies KConfig behaviour if CSE Lite SKU is integrated into
the coreboot. When the CSE Lite SKU is integrated, the KConfig prevents
writing to ME region but keeps read access enabled. Since CSE Lite driver
checks the signature of RW partition to identify the interrupted CSE
firmware update, so host must have read access to the ME region. Also, the
patch modifies the KConfig's help text to reflect the change.

Especially server boards, like the Supermicro X11SSM-F, often have a NMI
button and NMI functionality that can be triggered via IPMI. The purpose
of this is to cause the OS to create a system crashdump from a hang
system or for debugging.
Add code for enabling NMI interrupts on GPIOs configured with
PAD_CFG_GPI_NMI. The enabling mechanism is the same as SMI, so the SMI
function was copied and adapted. The `pad_community` struct gained two
variables for the registers.
Also register the NMI for LINT1 in the MADT in accordance to ACPI spec.
Test: Linux detects the NMI correctly in dmesg:

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 the boot process to ensure that the memory training parameters are

Replace the two obsolete LPID implementations with the new PEPD device.
The PEPD device gets included in the plaforms' `southbridge.asl`, since
it is required to load the `intel_pmc_core` module in Linux, which
checks for the _HID. (See CB:46469 for more info on that.)
There is no harm for mainboards not supporting S0ix, because the _DSM
function won't be called with the LPS0 UUID on such boards. Such boards
can use the debugging functionality of `intel_pmc_core`, too.

Add the _HID INT33A1 to PEPD to make Linux recognize it as "Intel Power
Engine" in the pmc core driver.
The _ADR gets dropped, because _HID and _ADR are mutually exclusive.
