+- Safe printf() functions

+- ULPI Layer Support:
+               The ULPI (UTMI Low Pin (count) Interface) PHYs are supported via
+               the generic ULPI layer. The generic layer accesses the ULPI PHY
+               via the platform viewport, so you need both the genric layer and
+               the viewport enabled. Currently only Chipidea/ARC based
+               viewport is supported.
+               To enable the ULPI layer support, define CONFIG_USB_ULPI and
+               CONFIG_USB_ULPI_VIEWPORT in your board configuration file.
 
 - MMC Support:
