This feature is not needed to get functional firmware,
so may be disabled for platforms with low memory space,
like baytrail and cherrytrail.

This kconfig collides with one of the same name in Zephyr. Rename it
for clarity ("MULTICORE" was picked for symmetry with the existing
"CORE_COUNT", though it's admittedly a little long...).

IDC task may be time consuming and has high priority,
what may make other tasks stall. To prevent this it should
have limited cycles budget per systick.

This will add DSP residency counters to Debug menu
It introduces generic DSP states R0, R1 and R2 with simple
reporting changes and tracing it in SRAM_REG mailbox.
Number of DSP residency states can be easily extended depending on platform needs.
In initial version CAVS support is added with the following approach:
R0 - in HPRO
R1 - in LPRO
R2 - LPS
with extra priority to R2 (LPS).

Zephyr and Kconfiglib support merging Kconfig menus across multiple git
repos. This requires relative inclusion paths.

Having both LP_SRAM (bool) and LP_MEMORY_BANKS (int) is error prone.
It's better to make LP_SRAM just a helper config that is set
to true if there is any LP memory bank in use.

Use of low power sequencer lowers power consumption, since
DSP may be completely turned off when calling waiti and then
powered on interrupt, booting via restore vector installed in

Adds options, that allow to select the supported interrupt
levels on given platform. Disabling any interrupt level
allows for less memory consumption. Currently all the options

This patch implements the new version of EDF scheduler.
This is the first basic implementation, which can be easily extended
in the future.
Previous implementation had two major flaws:
- Tasks could only be preempted based on the interrupt level on which
they have been scheduled, so it was limited based on the hardware.
- This led to the system not fully utilized, so we could never achieve
full EDF functionality.
The new implementation uses only one software interrupt and allows for
dynamic context switching between different tasks based on the deadline.
Also for some cases priority is taken into consideration e.g. for idle
and almost idle tasks, which don't have deadline at all and should be
executed only if the system is free. All other normal tasks should have
the same priority. Task chosen to be run is executed on passive level,
so automatically can be preempted by every interrupt. Every task has
its own private stack on which current context is saved and restored
if needed. Note that main firmware loop is task scheduled with
idle priority, so it will be executed only after every other task
is completed.

Apollolake+/i.MX have reset vector in ROM. So far we have
used platform config symbols to tell which platforms have
the reset vector in ROM.
Anyhow, things are starting to get ugly here with more
platforms to come so we add an internal config symbol
which will be set by each each platform when needed.
