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.

help
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.

help
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.
