This series adds DFU support for TI AM62 SK board and new since this version also for beagleplay.
Since the last revision, apart from beagleplay support the main changes are: * Documentation was added on how to use this functionality on both boards * the R5 configuration is now done via a config fragment rather then a full configuraiton * A new patch was added for dwc3 to work in device mode even if dr_mode is configured as otg. Avoiding the need for an explicit switch to periphal in the u-boot dts
I will also submit the dts changes to linux so that those can be dropped again in the near future (hopefully)
Changes in v4: - Add config dependency on SYSCON - Move defines and constants outside out of function scope - Don't force usb0 into peripheral mode - Move R5 dfu config to a config fragment rather then a full defconfig - Don't enable XHCI for the R5 SPL, unneeded
Change in v3: - Add dfu via environment rather then config headers - Enable usb nodes in all boot phases - Run savedefconfig to adjust to more recent u-boot
Changes in v2: - Switch dwc3 glue to a seperate driver rather then in dwc-generic - Minimize config changes to just DFU configuration - Only enable usb port 0 DFU in SPL - Create a seperate defconfig for R5
