The check was recently removed to allow callers to pass `count == 0`.
Dereferencing the `msg` array is invalid in that case, though. Linux,
where we borrowed the i2c interface from, also treats this with -EINVAL.

This reverts commit 5e6fd360de.
On nereid, the SSDT entry for the PCIe wifi device is missing, causing
wake-on-WLAN not to work since the _PRW is missing.
It seems like when commit 5e6fd360de changed the SSDT generation logic
for CNVi and PCIe wifi, it broke the PCIe case. `wifi_pcie_ops` are
never assigned to any device, so
`parent && parent->ops == &wifi_pcie_ops` always returns false, and the
`wifi_cnvi_ops` are used even for PCIe devices.
Undo the changes in that CL. This allows both the CNVi and PCIe cases to
work. That CL was meant to fix an issue with the CNVi _PRW containing
garbage, but I can't reproduce this when the change is undone.
It was also meant to fix the following error on CNVi devices, but I
don't see any errors with this change:
[ERROR] NONE missing set_resources

This removes unneeded and unused functionality in the driver as part of
an effort to make the driver more generic and useful. The things that
have been removed are: `DmaProperty` and its associated `is_untrusted`
config, `_DSD` generation, and the companion device functionality. This
driver isn't currently used anywhere so there won't be any issues from

Since there are many identifiers whose name contain "__unused" in
headers of musl libc, introducing a macro which expands "__unused" to
the source of a util may have disastrous effect during its compiling
under a musl-based platform.
However, it is hard to detect musl at build time as musl is notorious
for having explicitly been refusing to add a macro like "__MUSL__" to
announce its own presence.
Using __always_unused and __maybe_unused for everything may be a good
idea. This is how it works in the Linux kernel, so that would at least
make us match some other standard rather than doing our own thing
(especially since the other compiler.h shorthand macros are also
inspired by Linux).

comparing MRC hashes did not care if secdata mocking was enabled

The current 10ms timeout for SPI TPM IRQ is not enough for platforms
using ti50 (such as corsola). Therefore, introduce a new Kconfig option
'GOOGLE_TPM_IRQ_TIMEOUT_MS'.
For platforms using cr50, we need to support legacy pre-ready-IRQ cr50
factory images during the initial boot, so the timeout remains 100ms for
I2C TPM and 10ms for SPI TPM. For all the other platforms using ti50,
the default timeout is increased to 750ms, as suggested by the ti50 team
(apronin@google.com).

Add 'detect' flag which can be attached to devices which may or may not
be present at runtime, and for which coreboot should probe the i2c bus
to confirm device presence prior to adding an entry for it in the SSDT.
This is useful for boards which may utilize touchpads/touchscreens from
multiple vendors, so that only the device(s) present are added to the
SSDT. This relieves the burden from the OS to detect/probe if a device
is actually present and allows the OS to trust the ACPI _STA value.
