At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.

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
|

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.

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.
