This series adds DFU support for TI AM62 SK and beagleplay boards.
I have picked this series up from Sjoerd due to time constraints.
Since the last revision: * Removed dwc3 mode setting in favour of reinstating forced peripheral mode for usb0 * Use of config fragments for both r5 and a53 DFU configuration to reduce duplication * Typographical improvements to documentation
We plan to also submit the dts changes to linux so that those can be dropped again in the near future (hopefully)
Changes in v5: - Forcing usb0 into peripheral mode reinstated - Switch to config fragment for a53 DFU configuration - Use existing config fragment for a53 DFU configuration - Typographical corrections
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
