help
USBA is the integrated high-speed USB Device controller on some
AT91SAM9 and AT91CAP9 processors from Atmel.
The fifo_mode parameter is used to select endpoint allocation mode.
fifo_mode = 0 is used to let the driver autoconfigure the endpoints.
In this case, for ep1 2 banks are allocated if it works in isochronous
mode and only 1 bank otherwise. For the rest of the endpoints
only 1 bank is allocated.
fifo_mode = 1 is a generic maximum fifo size (1024 bytes) configuration
allowing the usage of ep1 - ep6
fifo_mode = 2 is a generic performance maximum fifo size (1024 bytes)
configuration allowing the usage of ep1 - ep3
fifo_mode = 3 is a balanced performance configuration allowing the
the usage of ep1 - ep8

This host controller driver emulates USB, looping all data transfer
requests back to a USB "gadget driver" in the same host. The host
side is the controller; the gadget side is the device. Gadget drivers
can be high, full, or low speed; and they have access to endpoints
like those from NET2280, PXA2xx, or SA1100 hardware.
This may help in some stages of creating a driver to embed in a
Linux device, since it lets you debug several parts of the gadget
driver without its hardware or drivers being involved.
Since such a gadget side driver needs to interoperate with a host
side Linux-USB device driver, this may help to debug both sides
of a USB protocol stack.
