Allocation now happens prior to device enumeration. The
step cbmem_add() is a no-op here, if reached for some
boards. The memset() here is also redundant and becomes
harmful with followup works, as it would wipe out the
CBMEM console and ChromeOS related fields without them
being set again.

This change updates the parameter passed into `lpss_set_power_state()`
from struct device * to pci_devfn_t. This allows the users in the
early stages to use pci_devfn_t instead of having to walk the device
tree to get a pointer to the relevant device structure. It is
important for optimizing out unnecessary components of the device tree
from the early stages.

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).

The CSE lite SKU has 2 CSE firmware boot partitions vs 3 for the "normal"

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.

replace all other copies with it. Since azalia_device.c is only built
when AZALIA_PLUGIN_SUPPORT is selected, select it where necessary.
This has the side-effect of building hda_verb.c from the mainboard

because its hda_verb.c was always wrong but wasn't being compiled.

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.

Move the southbridge_write_acpi_tables declaration from acpi.h to common
lpc_lib.h, as common LPC is always the caller. This removes a duplicate
declaration since all soc/intel devices use common LPC, but not all use
common ACPI. The southbridge_write_acpi_tables function is defined in acpi.c
with the other acpi functions.
Note that this would have the reverse problem if there is ever a non-common
LPC device.

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 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

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.

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
written back to SPI flash before performing a reset for CSE RW

This driver is for devices attached to a PCIe root port that support
Runtime D3. It creates the necessary PowerResource in the root port to
provide _ON/_OFF methods for which will turn off power and clocks to the
device when it is in the D3cold state.
The mainboard declares the driver in devicetree and provides the GPIOs
that control power/reset for the device attached to the root port and
the SRCCLK pin used for the PMC IPC mailbox to enable/disable the clock.
An additional device property is created for storage devices if it
matches the PCI storage class which is used to indicate that the storage
device should use D3 for power savings.

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.

Windows does not comply with the Low Power Idle S0 specification and
crashes with an `INTERNAL_POWER_ERROR` bluescreen when function 1, does
not return at least one device constraint, even when function 1 is
announced as being not available by the enum function. Returning an
empty package does not work.
At least the following Windows versions were verified to be affected:
- Windows 8.1 x64, release 6.3.9600
- Windoes 10 x64, version 1809, build 17763.379
- Windows 10 x64, version 1903, build 18362.53
- Windows 10 x64, version 2004, build 19041.508
- Windows 10 x64, version 20H2 / 2009, build 19042.450
To make Windows work on S0ix-enabled boards, return a dummy constraint
package with a disabled dummy device.
Since the device constraints are only used for debugging low power
states in Linux and probably also in Windows, there shouldn't be any
negative effect to S0ix. Real device constraint entries could be added
at a later point, if needed.
Note: to fully prevent the BSOD mentioned above the LPIT table is
required on Windows, too. The patch for this is WIP, see CB:32350.
If you want to test this, you need to applie the whole ACPI patch
series including the hacky LPIT test implementation from CB:47242:
https://review.coreboot.org/q/topic:%22low_power_idle_fix%22
Test: no bluescreen anymore on Clevo L140CU on all Windows versions
listed above and S0ix gets detected in `powercfg -a`.

CSE RW blob which will be used by coreboot to update CSE's RW partition,
is packed part of FW_MAIN_A and FW_MAIN_B. This will increase the size of
FW_MAIN_A and FW_MAIN_B. So, accordingly load and hash calculation of
FW_MAIN_A (or FW_MAIN_B) increases during verstage. It increases the boot
time by around 300ms.
The patch address the boot time by pulling CSE RW blob outside of
FW_MAIN_A and FW_MAIN_B. So, it creates new FMAP region within
RW_SECTION_A and RW_SECTION_B and adds CSE RW blob in the new regions
(ME_RW_A and ME_RW_B) as a CBFS file.

pmc_acpi_fill_ssdt_ipc_write_method() will provide a method in the SSDT

APL differs in not having the delay settings. However, the bits are
