Dear Remy Bohmer I am going to start "boot from USB Support" development for kirkwood. To sync with current USB framework in U-boot, and to reduce some rework at my side (since I am new to this driver). May you please provide some guidelines/howto this regard?
FYI below is details about Kirkwood USB controller: Kirkwood contains a Universal Serial Bus (USB 2.0) port that includes an embedded USB 2.0 PHY. The USB 2.0 interface contains a single dual-role controller that can act as a host or a peripheral controller (USB controller). A bridge connects the controller to the internal Mbus interface (USB bridge). Embedded USB 2.0 PHY features include: ?? 480 Mbps High Speed (HS)/ 12 Mbps Full Speed (FS) and 1.5 Mbps Low Speed (LS) serial data transmission rates ?? Synchronization/End-of-Packet (SYNC/EOP) generation and checking ?? Data and clock recovery from serial stream on the USB ?? Non Return to Zero Invert (NRZI) encoding/decoding with bit stuffing/unstuffing ?? Bit stuff error detections ?? Bit stuffing/unstuffing; bit stuff error detection ?? Holding registers to stage transmit and receive data ?? Supports USB 2.0 Test Modes ?? Ability to switch between FS and HS terminations/signaling ?? For more details, refer to the controller specification document USB-HS High-Speed Controller Core Reference. Regards..
