The PMC can be modelled as a syscon peripheral. Add a driver for this so that it can be accessed by drivers when needed. Enable it for tegra124 boards.

IVC (Inter-VM Communication) protocol is a Tegra-specific IPC
|
|
(Inter Processor Communication) framework. Within the context of
|
|
U-Boot, it is typically used for communication between the main CPU
|
|
and various auxiliary processors.

When loading U-Boot into RAM over USB protocols using tools such as
|
|
tegrarcm or L4T's exec-uboot.sh/tegraflash.py, Tegra's USB device
|
|
mode controller is initialized and enumerated by the host PC running
|
|
the tool. Unfortunately, these tools do not shut down the USB
|
|
controller before executing the downloaded code, and so the host PC
|
|
does not "de-enumerate" the USB device. This option shuts down the
|
|
USB controller when U-Boot boots to avoid leaving a stale USB device
|
|
present.

Tegra's boot ROM supports a mode whereby code may be downloaded and
|
|
flash-programmed over a USB connection. On dev boards, this is
|
|
typically entered by holding down a "force recovery" button and
|
|
resetting the CPU. However, not all boards have such a button (one
|
|
example is the Compulab Trimslice), so a method to enter RCM from
|
|
software is useful.
|
|
|
|
Even on boards other than Trimslice, controlling this over a UART
|
|
may be useful, e.g. to allow simple remote control without the need
|
|
for mechanical button actuators, or hooking up relays/... to the
|
|
button.
