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.

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

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