 The fastboot gadget relies on the USB download gadget, so the following
 options must be configured:
 
-CONFIG_USBDOWNLOAD_GADGET
+CONFIG_USB_GADGET_DOWNLOAD
 CONFIG_G_DNL_VENDOR_NUM
 CONFIG_G_DNL_PRODUCT_NUM
 CONFIG_G_DNL_MANUFACTURER
 
-The fastboot function is enabled by defining CONFIG_CMD_FASTBOOT and
-CONFIG_ANDROID_BOOT_IMAGE.
+NOTE: The CONFIG_G_DNL_VENDOR_NUM must be one of the numbers supported by
+the fastboot client. The list of vendor IDs supported can be found in the
+fastboot client source code (fastboot.c) mentioned above.

+The fastboot function is enabled by defining CONFIG_USB_FUNCTION_FASTBOOT,

 The fastboot protocol requires a large memory buffer for downloads. This
 buffer should be as large as possible for a platform. The location of the
-buffer and size are set with CONFIG_USB_FASTBOOT_BUF_ADDR and

+Fastboot partition aliases can also be defined for devices where GPT
+limitations prevent user-friendly partition names such as "boot", "system"
+and "cache".  Or, where the actual partition name doesn't match a standard
+partition name used commonly with fastboot.  Current implentation checks
+aliases when accessing partitions by name (flash_write and erase functions).
+To define a partition alias add an environment variable similar to:
+fastboot_partition_alias_<alias partition name>=<actual partition name>
+Example: fastboot_partition_alias_boot=LNX
