On some NXP platforms (e.g i.MX7ULP) the poweroff and reboot operations
are done via a separate remote core.
Typically Linux needs to send a message to the remote core and requests
for poweroff or reboot.
By default the communication between Linux core and the remote core is
is
From: Peng Fan
Current mailbox is blocking by default, but there are cases where we don't
need to wait for a response.
Linux just needs to send data to the remote processor, so let's
allow tx_block mode to be set (true/false) depending on usecase.
No functional changes.

tion_timeout. In the
poweroff or restart case, there is no need to wait, because after M4 got
the message, M4 will put A7 to reboot or poweroff.
patch 1 is to support non-blocking tx mailbox channel
patch 2 is to switch to non-blocking tx for system poweroff or restart.

After of_parse_phandle, we need of_node_put to decrease the refcount
of the device_node.

8 is not enough when we need more, such as resource table for remote cores
that booted before Linux Kernel, so enlarge IMX7D_RPROC_MEM_MAX to 32.
And also rename it to IMX_RPROC_MEM_MAX which make more sense.

Patch [1,3]/4 is new
Patch 4/4: Update commit message, drop unneeded code that already implemented
by core
This patchset is to support booted remote cores could be attached to linux.

Add i.MX8MN/P remote processor(Cortex-M7) support, we are using ARM
SMCCC to start/stop M core, not using regmap interface.

Add three methods IMX_RPROC_NONE(no need start/stop),
IMX_RPROC_MMIO(start/stop through mmio) and IMX_RPROC_SMC

i.MX7ULP A7 core runs under control of M4 core, M4 core starts by ROM
and powers most serivces used by A7 core, so A7 core has no power to
start and stop M4 core.

Add i.MX7ULP compatible.
We use i.MX7ULP dual mode and in which case i.MX7ULP A7 core runs under
control of M4 core, M4 core starts by ROM and powers most serivces used
by A7 core, so A7 core has no power to start and stop M4 core. So
clocks and syscon are not required.
