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

It may be useful at times to boot ADSP via backdoor, even
while system boots via front door. MB2 sets the ACAST in
front door, so ACAST setting from nvadsp driver is skipped
if that region is already enabled.
Above scheme will work for ADSP backdoor boot via SMMU
mapped memory, but not for physical memory, as the underlying
carveout memory is different between frontdoor and backdoor.

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

In cold boot stress test, it is observed that adsp OS
hung intermittently(1/276). Due to which
1) app init of adspff is not able to
complete as it does not receive start ack from adsp
2) wdt handler is triggered as adsp is hung for more
than 10 seconds.
When poweroff is issued in such case,
the alsactl save/restore job which is part of shutdown
sequence is hung as its unable to acquire lock held by
host adsp audio driver fn that initiated nvadsp_os_start.
Therefore, timeout is added while waiting for app init.
If app init fails to happen within timeout duration,
error status is received by nvadsp_os_start
which inturn is received by host side adsp audio driver.
This ensures that lock is released in case of adsff_init
failure in nvadsp_os_start function so that shutdown
can proceed without issue.

While enabling 'CONFIG_TEGRA_ADSP_FILEIO' following build error
is seen with v5.9-rc4 build.
ERROR: modpost: "sched_setscheduler" [drivers/platform/tegra/
nvadsp/nvadsp.ko] undefined!
This happens because sched_setscheduler() export is removed with
commit 616d91b68cd5 ("sched: Remove sched_setscheduler*() EXPORTs")
in upstream. The reason for removal is below.
Upstream commit 7318d4cc14c8 ("sched: Provide sched_set_fifo()")
provides sched_set_*() functions and suggests to convert existing
sched_setscheduler_*() calls to sched_set_*(). As per this
following updates are made for ADSP driver to work for v5.9.
- Use sched_set_fifo() whenever a high priority is required.
(However by default priority is set to MAX_RT/2)
- Use sched_set_fifo_low() whenever priority needs to be above
SCHED_NORMAL.
Since it is a recent change in upstream kernel above changes are
not applicable for previous kernels (v4.14 and v4.9). Hence these
can continue to use existing calls. Thus above changes are protected
under kernel version checks.

The errors appear to be related to 'uaccess.h' header and following
inclusion order is causing build failures for some reason. Checked with
other source files with below and same behavior is seen.
#include <asm/uaccess.h>
#include <linux/uaccess.h>
...
Issue goes away after replacing 'asm/uaccess.h' with 'linux/uaccess.h'.
It should be noted that latter header by default includes the former one.
For consistency this is done for other relevant ADSP files too.

Build error is seen on 5.4 kernel due to 'elf_hwcap' not being available.
Commit aec0bff757c9 ("arm64: HWCAP: encapsulate elf_hwcap") in upstream
removes direct expose of 'elf_hwcap' and instead provides a helper function
cpu_get_elf_hwcap() for it.
To fix build error this patch includes 'asm/hwcap.h' which works well for
all supported kernel versions in downstream. The macro ELF_HWCAP, from this
header, can be used for this purpose.
* For kernel < 5.4 : ELF_HWCAP --> elf_hwcap
* For kernel >= 5.4 : ELF_HWCAP --> cpu_get_elf_hwcap()
