Add suspend and resume support to Baytrail SST DSP. This is implemented by
unloading firmware modules and putting DSP into reset prior suspend and
restarting DSP again in normal boot state after resume.
Context restore for running streams is implemented by scheduling a work from
sst_byt_pcm_trigger() that will allocate a stream with existing parameters
and start it from last known buffer position before suspend.

We have to save the physical address of extended firmware block in the
beginning of mailbox every time when we boot the DSP firmware since that
mailbox address is re-used after DSP firmware is running. Otherwise DSP
firmware will get bogus extended firmware block address during next DSP
boot.
Currently this is not problem but becomes when DSP runtime rebooting is
implemented. Prepare for that by moving extended firmware address saving
from sst_byt_init() to sst_byt_boot().

Baytrail ADSP stream IPC simplifies a little by moving IPC_IA_START_STREAM
construction and sending directly into sst_byt_stream_start() from
sst_byt_stream_operations(). This is because IPC_IA_START_STREAM is only
stream IPC with extra message data so this move saves a few code lines.
Main motivation for this is to prepare for passing stream start position
to sst_byt_stream_start() which will be needed in resume code.

This is for preparing suspend/resume support but can give also more
safeguard against concurrent timestamp structure access between DSP firmware
and host.
Now DSP DMA pointer is sampled in each pcm pointer callback in
sst_byt_pcm_pointer() but that is unneeded since DSP updates the timestamp
period basis and can potentially be racy if sst_byt_pcm_pointer() is called
when DSP is updating the timestamp.
By taking DSP DMA pointer only after period elapsed IPC messages in
byt_notify_pointer() and returning stored hw pointer in
sst_byt_pcm_pointer() there is less risk for concurrent access.
The same stored hw pointer can be also used in suspend/resume code for
restarting the stream at the same position.

[ 11.886418] gsmi: Log Shutdown Reason 0x03
The virtual address, ffffc90121700000, was out of range. The virtual
address is calculated by adding LPE base address with an offset:
sst_memcpy32(dsp->addr.lpe + data->offset, data->data, data->size);
The offset is calculated in sst_byt_parse_module, by subtraction of
two virtual addresses dsp->addr.fw_ext and dsp->addr.lpe:
block_data.offset = block->ram_offset + (dsp->addr.fw_ext - dsp->addr.lpe);
These virtual addresses are assigned by kernel from ioremap:
sst->addr.lpe = ioremap(pdata->lpe_base, pdata->lpe_size);
sst->addr.fw_ext = ioremap(pdata->fw_base, pdata->fw_size);
In current driver code, offset is defined as unsigned int32:
struct sst_module_data {
...
u32 offset; /* offset in FW file */
};
Most of the time kernel assigned virtual addresses with addr.fw_ext
greater than addr.lpe. But sometimes it was the other way round.
Fix the problem by declaring offset as signed int32_t.

Use table based setup to register the controls and DAPM widgets and routes.
This on one hand makes the code a bit cleaner and on the other hand
the board level DAPM elements get registered in the card's DAPM context rather
than in the CODEC's DAPM context.
The mfld_machine driver is a bit special in that it directly writes to one of
the CODEC registers from one of the control handlers. Previous to this patch it
was able to get a pointer to the CODEC from the control, since the control was
registered with the CODEC. This won't be possible anymore once the control is
registered with the card. Since there are already global variables in the driver
accessed in the same function the patch adds a global variable that holds a
pointer to the CODEC and uses that.

Disable build on non X86 architectures except for compile testing. This fixes
the following build errors on PPC and adds an option for testing the build on other
architectures as suggested by Mark Brown :-

sound/soc/intel/sst-dsp.c:218:2: error: implicit declaration of function 'memcpy_toio' [-Werror=implicit-function-declaration]
memcpy_toio(sst->mailbox.out_base, message, bytes);

Initial implementation of this driver focused only matching SST ACPI ID
with single machine driver and same firmware file per platform. It was known
restriction to be improved incrementally.
This patch is now changing this that SST ACPI ID refers purely to platform
specific data which refers to machine drivers on this platform, not vice
versa.
Matching machine driver is found by looking at ACPI ID which would best
match with the driver. Typically this would be the ACPI ID of audio codec
but is not tied to it.
This patch also changes that DSP firmware name is machine not platform
specific.

We originally thought to request SST audio DSP firmware during the SST
platform driver initialization. However plain request_firmware doesn't
work in driver probe paths if userspace is not ready to handle it. For
instance when drivers are built-in.
Implementing asynchronous firmware request in SST platform driver
initialization complicates code needlessly since it anyway will fail if
firmware is missing.
This is more simple to handle by requesting firmware asynchronously in
sst_acpi_probe() and register SST platform only after firmware is loaded.

Move fw_base and fw_size fields in struct sst_pdata under ACPI data for
clarifying that these are not related to firmware file but for platform
specific extended firmware area reserved by the BIOS.

Provide services for Intel SST drivers to load SST modular firmware.
SST Firmware can be made up of several modules. These modules can exist
within any of the compatible SST memory blocks. Provide a generic memory
block and firmware module manager that can be used with any SST firmware
and core.

Most of the SST devices will be exposed as ACPI devices. It makes sense to
avoid duplication of the driver enumeration logic and concentrate the functionality
into a single ACPI SST enumeration file.
Idea of this loader is to parse data we get from ACPI and to be able to load
needed other SST drivers and ASoC machine driver runtime based on single
ACPI ID what BIOS gives to us.

Add support for Intel Smart Sound Technology (SST) audio DSPs.
This driver provides the low level IO, reset, boot and IRQ management
for Intel audio DSPs. These files make up the low level part of the SST
audio driver stack and will be used by many Intel SST cores like
Haswell, Broadwell and Baytrail.
SST DSPs expose a memory mapped region (shim) for config and control.
The shim layout is mostly shared without much modification across cores
and this driver provides a uniform API to access the shim and to enable
basic shim functions. It also provides functionality to abstract some shim
functions for cores with different shim features.

Resent with correct email for Mark.
In order to differentiate the different Intel SST audio core drivers we
need to rename the current drivers with a mfld prefix. This also includes
renaming in the Makefile and Kconfig

The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.
