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

Hi Steve,
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

Applied to u-boot-dfu (the whole series).
Thanks for patches!
