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.

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

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