[U-Boot] [PATCH v1 0/3] Add support for DFU boot to DRA7-based EVMs
The purpose of this series is to provide the SPL with ability to boot u-boot from DFU. The DRA7x can download the SPL over the USB1 port when configured in the USB peripheral boot mode. Details on how this can be acheived with the EVMs can found here http://www.ti.com/lit/an/sprac33/sprac33.pdf Once the SPL is loaded, u-boot can be downloaded on the same USB1 port through DFU.
This boot flow has been tested on DRA7-evm, DRA72-evm-rec, DRA71-evm and DRA76-evm
