Currently, the MMCONF Kconfigs only support the Enhanced Configuration
Access mechanism (ECAM) method for accessing the PCI config address
space. Some platforms have a different way of mapping the PCI config
space to memory. This patch renames the following configs to
make it clear that these configs are ECAM-specific:
- NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT
- MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT
- MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS
- MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER
- MMCONF_LENGTH --> ECAM_MMCONF_LENGTH
Please refer to CB:57861 "Proposed coreboot Changes" for more
details.

There is no platform in our tree that requires the PCI MMIO ops but
doesn't want the pci_s_* definitions. The only case where we include
the `pci_mmio_cfg.h` header but don't want the pci_s_* functions to
use MMIO is on older x86 platforms, so move the guard there.

This API will hide all the complexity of preloading a CBFS file. It
makes it so the callers simply specify the file to preload and CBFS
takes care of the rest. It will start a new thread to read the file into
the cbfs_cache. When the file is actually required (i.e., cbfs_load,
etc) it will wait for the preload thread to complete (if it hasn't
already) and perform verification/decompression using the preloaded
buffer. This design allows decompression/verification to happen in the
main BSP thread so that timestamps are correctly reflected.

Introduce the `smbios_dev_info` devicetree keyword to specify the
instance ID and RefDes (Reference Designation) of onboard devices.
Example syntax:
device pci 1c.0 on # PCIe Port #1
device pci 00.0 on
smbios_dev_info 6
end
end
device pci 1c.1 on # PCIe Port #2
device pci 00.0 on
smbios_dev_info 42 "PCIe-PCI Time Machine"
end
end
The `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` Kconfig option enables using
this syntax to control the generated Type 41 entries. When this option
is enabled, Type 41 entries are only autogenerated for devices with a
defined instance ID. This avoids having to keep track of which instance
IDs have been used for every device class.
Using `smbios_dev_info` when `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` is not
enabled will result in a build-time error, as the syntax is meaningless
in this case. This is done with preprocessor guards around the Type 41
members in `struct device` and the code which uses the guarded members.
Although the preprocessor usage isn't particularly elegant, adjusting
the devicetree syntax and/or grammar depending on a Kconfig option is
probably even worse.

Selecting CPU_X86_CACHE_HELPER only added the x86_enable_cache wrapper
function around enable_cache which additionally wrote a POST code to
port 0x80 and printed a message to the console. This function was only
called during multi-processor initialization in ramstage via the init
function pointer in the CPU's device operations struct and was run on
all cores, so the message on the console was printed once per CPU core.
This patch replaces all x86_enable_cache calls by calls to enable_cache
and removes the wrapper function and the Kconfig symbol
CPU_X86_CACHE_HELPER which was used to only add this when the
corresponding CPUs used the x86_enable_cache wrapper function.

case in the common code like

There is currently a fundamental flaw in the current cpu_info()
implementation. It assumes that current stack is CONFIG_STACK_SIZE
aligned. This assumption breaks down when performing SMM relocation.
The first step in performing SMM relocation is changing the SMBASE. This
is accomplished by installing the smmstub at 0x00038000, which is the
default SMM entry point. The stub is configured to set up a new stack
with the size of 1 KiB (CONFIG_SMM_STUB_STACK_SIZE), and an entry point
of smm_do_relocation located in RAMSTAGE RAM.
This means that when smm_do_relocation is executed, it is running in SMM
with a different sized stack. When cpu_info() gets called it will be
using CONFIG_STACK_SIZE to calculate the location of the cpu_info
struct. This results in reading random memory. Since cpu_info() has to
run in multiple environments, we can't use a compile time constant to
locate the cpu_info struct.
This CL introduces a new way of locating cpu_info. It uses a per-cpu
segment descriptor that points to a per-cpu segment that is allocated on
the stack. By using a segment descriptor to point to the per-cpu data,
we no longer need to calculate the location of the cpu_info struct. This
has the following advantages:
* Stacks no longer need to be CONFIG_STACK_SIZE aligned.
* Accessing an unconfigured segment will result in an exception. This
ensures no one can call cpu_info() from an unsupported environment.
* Segment selectors are cleared when entering SMM and restored when
leaving SMM.
* There is a 1:1 mapping between cpu and cpu_info. When using
COOP_MULTITASKING, a new cpu_info is currently allocated at the top of
each thread's stack. This no longer needs to happen.
This CL guards most of the code with CONFIG(CPU_INFO_V2). I did this so
reviewers can feel more comfortable knowing most of the CL is a no-op. I
would eventually like to remove most of the guards though.
This CL does not touch the LEGACY_SMP_INIT code path. I don't have any
way of testing it.
The %gs segment was chosen over the %fs segment because it's what the
linux kernel uses for per-cpu data in x86_64 mode.
BUG=b:194391185, b:179699789
TEST=Boot guybrush with CPU_INFO_V2 and verify BSP and APs have correct
%gs segment. Verify cpu_info looks sane. Verify booting to the OS
works correctly with COOP_MULTITASKING enabled.

On AArch64 platforms, GIC initialization is generally the job of Trusted
Firmware and shouldn't be necessary in coreboot. Only the ancient T210
platform (which was started before we had decided on using Trusted
Firmware) calls this code, and even there they have a comment wondering
"do we still need this?". I'm just gonna assume (without testing because
that board is ancient and I'm lazy) that they don't, and that the TF GIC
initialization[1] is sufficient here. Remove this obsolete driver.

vboot_reference is introducing a new field (ctx) to store the current
boot mode in crrev/c/2944250 (ctx->bootmode), which will be leveraged
in both vboot flow and elog_add_boot_reason in coreboot.
In current steps of deciding bootmode, a function vb2ex_ec_trusted
is required. This function checks gpio EC_IN_RW pin and will return
'trusted' only if EC is not in RW. Therefore, we need to implement
similar utilities in coreboot.
We will deprecate vb2ex_ec_trusted and use the flag,
VB2_CONTEXT_EC_TRUSTED, in vboot, vb2api_fw_phase1 and set that flag
in coreboot, verstage_main.
Also add a help function get_ec_is_trusted which needed to be
implemented per mainboard.

The call to the `get_smbios_data` device operation is followed by
calls to unconditional default functions, which lacks flexibility.
Instead, have devices that implement `get_smbios_data` call these
default functions as needed.
Most `get_smbios_data` implementations are in mainboard code, and are
bound to the root device. The default functions only operate with PCI
devices because of the `dev->path.type != DEVICE_PATH_PCI` checks, so
calling these functions for non-PCI devices is unnecessary. QEMU also
implements `get_smbios_data` but binds it to the domain device, which
isn't PCI either.
