Subject: [PATCH 10/10] USB ppc4xx: Add Synopsys DWC OTG driver kernel
configuration and Makefile
From: Tirumala Marri <tmarri at apm.com>
Add Synopsys DesignWare HS USB OTG driver kernel configuration.
Synopsys OTG driver may operate in host only, device only, or OTG mode.
The driver also allows user configure the core to use its internal DMA
or Slave (PIO) mode.
