+SunxiUSBDriver
+~~~~~~~~~~~~~~
+A :any:`SunxiUSBDriver` is used to upload an image into a device in the
+*Allwinner loader state*. This is useful to bootstrap a bootloader onto a
+device.
+
+Note that sunxi is the common name for Allwinner SoCs, since they have product
+codes like sun50i, sun7i, etc.
+
+The load happens in two stages, first SPL and then U-Boot proper.

+Arguments:
+  - loadaddr (int): address to use when loading U-Boot. This depends on the

+    *CONFIG_TEXT_BASE* value in U-Boot

+SamsungUSBDriver
+~~~~~~~~~~~~~~~~
+A :any:`SamsungUSBDriver` is used to upload an image into a device in the
+*Samsung loader state*. This is useful to bootstrap a bootloader onto a device.
+
+The load happens in three stages: BL1, SPL and U-Boot proper.

+Arguments:
+  - bl1 (str): Filename of the BL1 file which sets up the SoC
+  - bl1_loadaddr (int): Load address of the BL1 file. This depends on the SoC
+    spl_load_addr (int): Load address of SPL. The easiest way to find this value

+TegraUSBDriver
+~~~~~~~~~~~~~~
+A :any:`TegraUSBDriver` is used to upload an image into a device in the
+*Nvidia Tegra loader state*. This is useful to bootstrap a bootloader onto a
+device.
+
+The load happens in a single stage, with U-Boot proper sent along with a
+*BCT* (Binary Control Tool) configuration file which contains memory timings,
+etc.

+
+Arguments:
+  - loadaddr (int): address to use when loading the firmware. This depends on
+    the SoC being used. For U-Boot the easiest way to find this value is to
+    check the *CONFIG_TEXT_BASE* value
+  - bct (str): path to the BCT (configuration file)
+  - usb_path (str): USB device to program. This can be obtained using udevadm
+    with the USB bus and device number. For example
+    `udevadm info /dev/bus/usb/003/042` then look at DEVPATH.
+  - image (str): Optional image filename
