ASoC: SOF: core: Implement IPC version fallback if firmware files are missing 
If a firmware file is missing for the selected IPC type then try to switch
to other supported IPC type and check if that one can be used instead.

If for example a platform is changed to IPC4 as default version but the
given machine does not yet have the needed topology file created then we
will fall back to IPC3 which should have all the needed files.

Relocate the sof_init_environment() to be done at a later phase, in
sof_probe_continue().

This will only have changes in behavior if
CONFIG_SND_SOC_SOF_PROBE_WORK_QUEUE is enabled (Intel HDA platforms) by
not failing the module probe, but it is not going to be different case
compared to for example failed firmware booting or topology loading error.

menuconfig SND_SOC_SOF_TOPLEVEL
bool "Sound Open Firmware Support"
help
This adds support for Sound Open Firmware (SOF). SOF is free and
generic open source audio DSP firmware for multiple devices.
Say Y if you have such a device that is supported by SOF.
If unsure select "N".
if SND_SOC_SOF_TOPLEVEL
config SND_SOC_SOF_PCI_DEV
tristate
config SND_SOC_SOF_PCI
tristate "SOF PCI enumeration support"
depends on PCI
help
This adds support for PCI enumeration. This option is
required to enable Intel Skylake+ devices.
For backwards-compatibility with previous configurations the selection will
be used as default for platform-specific drivers.
Say Y if you need this option.
If unsure select "N".
config SND_SOC_SOF_ACPI
tristate "SOF ACPI enumeration support"
depends on ACPI || COMPILE_TEST
help
This adds support for ACPI enumeration. This option is required
to enable Intel Broadwell/Baytrail/Cherrytrail devices.
For backwards-compatibility with previous configurations the selection will
be used as default for platform-specific drivers.
Say Y if you need this option.
If unsure select "N".
config SND_SOC_SOF_ACPI_DEV
tristate
config SND_SOC_SOF_OF
tristate "SOF OF enumeration support"

help
This option enables the data probing feature that can be used to
gather data directly from specific points of the audio pipeline.
This option is not user-selectable but automagically handled by
'select' statements at a higher level.

help
This option is not user-selectable but automagically handled by
'select' statements at a higher level.
config SND_SOC_SOF_DEVELOPER_SUPPORT
bool "SOF developer options support"
depends on EXPERT && SND_SOC_SOF
help
This option unlocks SOF developer options for debug/performance/
code hardening.
Distributions should not select this option, only SOF development
teams should select it.
Say Y if you are involved in SOF development and need this option.
If not, select N.
if SND_SOC_SOF_DEVELOPER_SUPPORT
config SND_SOC_SOF_FORCE_PROBE_WORKQUEUE
bool "SOF force probe workqueue"
select SND_SOC_SOF_PROBE_WORK_QUEUE
help
This option forces the use of a probe workqueue, which is only used
when HDaudio is enabled due to module dependencies. Forcing this
option is intended for debug only, but this should not add any
functional issues in nominal cases.
Say Y if you are involved in SOF development and need this option.
If not, select N.
config SND_SOC_SOF_NOCODEC
tristate
config SND_SOC_SOF_NOCODEC_SUPPORT
bool "SOF nocodec static mode support"
help
This adds support for a dummy/nocodec machine driver fallback
option if no known codec is detected. This is typically only
enabled for developers or devices where the sound card is
controlled externally.
This option is mutually exclusive at build time with the Intel HDAudio support.
Selecting it may have negative impacts and prevent e.g. microphone
functionality from being enabled on Intel CoffeeLake and later
platforms.
Distributions should not select this option!
Say Y if you need this nocodec fallback option.
If unsure select "N".
config SND_SOC_SOF_STRICT_ABI_CHECKS
bool "SOF strict ABI checks"
help
This option enables strict ABI checks for firmware and topology
files.
When these files are more recent than the kernel, the kernel
will handle the functionality it supports and may report errors
during topology creation or run-time usage if new functionality
is invoked.
This option will stop topology creation and firmware load upfront.
It is intended for SOF CI/releases and not for users or distros.
Say Y if you want strict ABI checks for an SOF release.
If you are not involved in SOF releases and CI development,
select "N".
config SND_SOC_SOF_ALLOW_FALLBACK_TO_NEWER_IPC_VERSION
bool "SOF allow fallback to newer IPC version"
help
This option will allow the kernel to try to 'fallback' to a newer IPC
version if there are missing firmware files to satisfy the default IPC
version.
IPC version fallback to older versions is not affected by this option,
it is always available.
Say Y if you are involved in SOF development and need this option.
If not, select N.
config SND_SOC_SOF_DEBUG
bool "SOF debugging features"
help
This option can be used to enable or disable individual SOF firmware
and driver debugging options.
Say Y if you are debugging SOF FW or drivers.
If unsure select "N".
if SND_SOC_SOF_DEBUG
config SND_SOC_SOF_NOCODEC_DEBUG_SUPPORT
bool "SOF nocodec debug mode support"
depends on !SND_SOC_SOF_NOCODEC_SUPPORT
help
This adds support for a dummy/nocodec machine driver fallback
option.
Unlike the SND_SOC_SOF_NOCODEC_SUPPORT, this option is NOT
mutually exclusive at build with the Intel HDAudio support. The
selection will be done depending on command line or modprobe.d settings
Distributions should not select this option!
Say Y if you need this nocodec debug fallback option.
If unsure select "N".
config SND_SOC_SOF_FORCE_NOCODEC_MODE
bool "SOF force nocodec Mode"
depends on SND_SOC_SOF_NOCODEC_SUPPORT
help
This forces SOF to use dummy/nocodec as machine driver, even
though there is a codec detected on the real platform. This is
typically only enabled for developers for debug purposes, before
codec/machine driver is ready, or to exclude the impact of those
drivers.
Say Y if you need this force nocodec mode option.
If unsure select "N".
config SND_SOC_SOF_DEBUG_XRUN_STOP
bool "SOF stop on XRUN"
help
This option forces PCMs to stop on any XRUN event. This is useful to
preserve any trace data and pipeline status prior to the XRUN.
Say Y if you are debugging SOF FW pipeline XRUNs.
If unsure select "N".
config SND_SOC_SOF_DEBUG_VERBOSE_IPC
bool "SOF verbose IPC logs"
help
This option enables more verbose IPC logs, with command types in
human-readable form instead of just 32-bit hex dumps. This is useful
if you are trying to debug IPC with the DSP firmware.
If unsure select "N".
config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
bool "SOF force to use IPC for position update on SKL+"
help
This option forces to handle stream position update IPCs and run PCM
elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
On platforms (e.g. Intel SKL-) where position update IPC is the only
one choice, this setting won't impact anything.
If you are trying to debug pointer update with position IPCs or where
DPIB/posbuf is not ready, select "Y".
If unsure select "N".
config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
bool "SOF enable debugfs caching"
help
This option enables caching of debugfs
memory -> DSP resource (memory, register, etc)
before the audio DSP is suspended. This will increase the suspend
latency and therefore should be used for debug purposes only.
Say Y if you want to enable caching the memory windows.
If unsure, select "N".
config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE
bool "SOF enable firmware trace"
help
The firmware trace can be enabled either at build-time with
this option, or dynamically by setting flags in the SOF core
module parameter (similar to dynamic debug).
If unsure, select "N".
config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST
tristate "SOF enable IPC flood test"
depends on SND_SOC_SOF
select SND_SOC_SOF_CLIENT
help
This option enables a separate client device for IPC flood test
which can be used to flood the DSP with test IPCs and gather stats
about response times.
Say Y if you want to enable IPC flood test.
If unsure, select "N".
config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST_NUM

Select the number of IPC flood test clients to be created.
config SND_SOC_SOF_DEBUG_IPC_MSG_INJECTOR
tristate "SOF enable IPC message injector"
depends on SND_SOC_SOF
select SND_SOC_SOF_CLIENT
help
This option enables the IPC message injector which can be used to send
crafted IPC messages to the DSP to test its robustness.
Say Y if you want to enable the IPC message injector.
If unsure, select "N".
config SND_SOC_SOF_DEBUG_IPC_KERNEL_INJECTOR
tristate "SOF enable IPC kernel injector"
depends on SND_SOC_SOF
select SND_SOC_SOF_CLIENT
help
This option enables the IPC kernel injector which can be used to send
crafted IPC messages to the kernel to test its robustness against
DSP messages.
Say Y if you want to enable the IPC kernel injector.
If unsure, select "N".
config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT
bool "SOF retain DSP context on any FW exceptions"
help
This option keeps the DSP in D0 state so that firmware debug
information can be retained and dumped to userspace.
Say Y if you want to retain DSP context for FW exceptions.
If unsure, select "N".
