Below changes are made to support future
extensibility for new chips:
- Chip data field 'adsp_prid' is added to specify DSP ID
- Chip data field 'adsp_elf' is added to specify ELF file name
- DT property "nvidia,cluster_mem" is added to specify cluster
internal memories; ELF segments will be loaded into these
using intermediate shadow buffers so that unaligned access
is avoided
- "nvidia,adsp_mem" entries are made optional (0x0 in the size
field will indicate bypass)
- Chip extension functions 'set_boot_vec' and 'set_boot_freqs'
are added to support chip specific settings

There is a decompress_done flag in the adsp OS firmware
that was earlier used to indicate that decompress is done
at the adsp os cold boot
However this flag cannot be part of firmware
as fw needs to authenticated at the sc7 resume as well and
hence the fw should not have modifications
On fw side, the flag is removed. Instead the same information
is preserved across sc7 cycles via HWMBOX5 and this driver
enables the decompress bit to indicate the same to adsp at
cold start

ACAST settings are expected to be done by the driver in backdoor
boot. Provision is added to read the ACAST address ranges and
the SMMU stream ID from DT.
ACAST settings are done either for physical memory, or for SMMU
mapped memory, as per the backdoor boot configuration.
Also, call to ACAST init function is moved from runtime resume
to device probe.

Provision is made to pass the Tegra platform information to ADSP
("nvidia,tegra_platform" DT property, as per enum tegra_platform);
this will be useful to convey whether the platform is CMODEL, in
which case the ADSP may take CMODEL specific paths, like using
HSP shared interrupts.
Upper 16 bits of nvadsp_os_args.chip_id is used to convey the
platform information; this may be improved in future as a
separate structure member.

Add Interconnect API support for ADSP Memory bandwidth requirement
handling.
From Kernel 4.14 and beyond
- On T23X and newer platforms, the interconnects driver will be initialized
and calls to BWMGR will be stubbed out.
- On T194 and earlier platforms, BWMGR driver will be initialized and calls
to interconnect framework will be stubbed out.
Added code check with K5.9 as mc_utils.h header is present from K5.9 build
For Kernel 4.9 and earlier
- T23x will not be supported.
- T194 and earlier platforms will use BWMGR. Interconnect framework is not
available.

NVADSP driver tries to allocate shared memory for ADSP
by requesting the DMA APIs to allocate at address hardcoded
in DT. This poses an issue where if kernel has already allocated
that memory to a different driver in same iommu group, this
memory becomes unavailable and ADSP does not boot
Adding support to allocate shared memory for ADSP dynamically

Change adds pm ops in nvadsp driver to support suspend/resume
functionality. Without the change, if playback/capture is active when
system suspend occurs, the nvadsp driver is never suspended and hence
the clocks are not disabled.
In terms of power sequence device driver registered as late_suspend are
suspended first followed by noirq pm ops registred devices.
adsp_audio device node is registered for late suspend. To make sure
adsp_audio suspend is called first nvadsp is registered under noirq pm
ops

This is since the new agic driver is based on a device-driver model

When ADSP OS is loaded from adsp.elf, it loads two sections : adsp os
and the vector table. The vector table is copied to a local buffer
before writing to the EVP registers.
There is a probability that, if the adsp.elf is hacked / modified by
an attacker, it can write to other APE register spaces. Hence, the
destination address obtained from the elf is checked with evp base
before copying.
Also, this fixes out of array-bound writing to evp buffer.
