+ 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

+ does not "de-enumerate" the USB device. This option shuts down the

-DFU TEST CASE DESCRIPTION:
-
-The prerequisites for running this script are assured by
-dfu_gadget_test_init.sh, which is automatically invoked by dfu_gadget_test.sh.
-In this file user is able to generate their own set of test files by altering
-the default set of TEST_FILES_SIZES variable.
-The dfu_gadget_test_init.sh would generate test images only if they are not
-already generated.
-
-On the target device, environment variable "dfu_alt_info" must contain at
-least:
-
- dfu_test.bin fat 0 6;dfudummy.bin fat 0 6
-
-Depending on your device, you may need to replace "fat" with
-"ext4", and "6" with the relevant partition number. For reference please
-consult the config file for TRATS/TRATS2 devices
-(../../include/configs/trats{2}.h)
-
-One can use fat, ext4 or any other supported file system supported by U-Boot.
-These can be created by exporting storage devices via UMS (ums 0 mmc 0) and
-using standard tools on host (like mkfs.ext4).
-
-Example usage:
-1. On the target:
- setenv dfu_alt_info dfu_test.bin fat 0 6\;dfudummy.bin fat 0 6
- dfu 0 mmc 0
-2. On the host:
- test/dfu/dfu_gadget_test.sh X Y [test file name] [usb device vendor:product]
- e.g. test/dfu/dfu_gadget_test.sh 0 1
- or
- e.g. test/dfu/dfu_gadget_test.sh 0 1 ./dat_960.img
- or
- e.g. test/dfu/dfu_gadget_test.sh 0 1 0451:d022
- or
- e.g. test/dfu/dfu_gadget_test.sh 0 1 ./dat_960.img 0451:d022
-
-... where X and Y are dfu_test.bin's and dfudummy.bin's alt setting numbers.
-They can be obtained from dfu-util -l or $dfu_alt_info.
-It is also possible to pass optional [test file name] to force the script to
-test one particular file.
-If many DFU devices are connected, it may be useful to filter on USB
-vendor/product ID (0451:d022).
-One can get them by running "lsusb" command on a host PC.

-UMS test script.
-
-ums_gadget_test.sh
-==================
-
-Example usage:
-1. On the target:
- create UMS exportable partitions (with e.g. gpt write), or specify a
- partition number (PART_NUM) as "-" to use the entire device
- ums 0 mmc 0
-2. On the host:
- sudo test/ums/ums_gadget_test.sh VID PID PART_NUM [-f FILE_SYSTEM] [test_file]
- e.g. sudo test/ums/ums_gadget_test.sh 0525 a4a5 6 -f vfat ./dat_14M.img
-
-... where:
- VID - UMS device USB Vendor ID
- PID - UMS device USB Product ID
- PART_NUM - is the partition number on which UMS operates or "-" to use the
- whole device
-
-Information about available partitions on the target one can read with using
-the 'mmc part' or 'part list' commands.
-
-The partition num (PART_NUM) can be specified as '-' for using the whole device.
-
-The [-f FILE_SYSTEM] optional switch allows for formatting target partition to
-FILE_SYSTEM.
-
-The last, optional [test_file] parameter is for specifying the exact test file
-to use.
