From e6607cffef965011ef0ddc0fbe6f4b7c0d53aeec Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Thu, 29 May 2014 15:29:40 -0600 Subject: ARM: tegra: enable USB device mode and UMS on some boards For each of Jetson TK1, Venice2, and Beaver: - Enable the first USB controller in DT, and describe its configuration. - Enable USB device/gadget support. This allows the user to type e.g. "ums 0 mmc 0" at the command-line to cause U-Boot to act a USB device implementing the USB Mass Storage protocol, and expose MMC device 0 that way. This allows a host PC to mount the Tegra device's MMC, partition it, and install a filesystem on it.
