Hello everyone, This is version two of my series which adds support for the Renesas USBF controller, which is used in the RZ/N1 SoC. This will facilitate exposing USB gadgets from RZ/N1 SoCs in U-Boot.
The driver was ported from the Linux kernel. The following features were removed to reduce the memory footprint of the driver, and to avoid including features not relevant to U-Boot: - Suspend/resume - Handling of endpoints > 2 - Dynamic detection of endpoint DMA capability (DMA capability is predetermined for each endpoint anyway).
