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.

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

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