Hi,
I gave your patches a run on an AT91CAP9 and had limited success with
them (usb seems to work, usb storage do not):
$ egrep FAT\|USB include/configs/at91cap9adk.h
#define CONFIG_CMD_USB 1
/* USB */
#define CONFIG_USB_OHCI_NEW 1
#define CFG_USB_OHCI_CPU_INIT 1
#define CFG_USB_OHCI_REGS_BASE 0x00700000 /* AT91_BASE_UHP */
#define CFG_USB_OHCI_SLOT_NAME "at91cap9"
#define CFG_USB_OHCI_MAX_ROOT_PORTS 2
#define CONFIG_USB_STORAGE 1
#define CONFIG_CMD_FAT 1
