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

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

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