ARM: tegra: enable DFU too
Enable DFU protocol support (via the "dfu" command) on Tegra boards where USB device/gadget mode is enabled. Note that for DFU to operate correctly on Tegra, we still need some DFU fixes/enhancements that are going through the DFU -> USB trees. However, the code builds just fine without those changes, and applying this patch now will allow both sets of patches to meet in the main U-Boot tree much more quickly. In order to run test/dfu/dfu_gadget_test.sh, you would need to add the following to the board configuration: CONFIG_EXT4_WRITE CONFIG_CMD_EXT4_WRITE However, I haven't enabled those here, since I believe the main use-case for DFU on Tegra is raw flash writing, rather than filesystem access, so we don't need the additional code-size hit. However, I could be persuaded otherwise! We should probably add a separate test script for raw flash access.
