[U-Boot] [PATCH v3 0/3] This series implements fastboot on the "bcm28155_ap" boards.

[Steve Rae]

The OTG hardware is a DWC2 controller and this series uses the
existing gadget driver ("s3c_udc_otg.c").

Changes in v3:
- use static inline functions instead of macros
- update the delay (2ms) to match the kernel code
- use "SZ_1M"
- undefine the 8-bit phy interface

Changes in v2:
- rebased against u-boot-dfu
