[PATCH v5 0/6] Add DFU and usb boot for TI am62x SK and beagleplay

[Martyn Welch]

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
