Are you sure ? The cs908 also does not have an otg connector,
as said it has 2 usb-a receptacles, with the following usb "routing":

usb0 (otg): usb-a receptacle 1 (labeled 1 on the box, 0 on the print)
usb1 (ehci): routed to internal wifi
usb2 (ehci): usb-a receptacle 2 (labeled 2 on both the box and the print)

I'm using fel mode with an usb-a <-> usb-a cable connected to usb0 on
the cs908. The cs908 has no fel button, so I've hooked up the serial console,
and then keep 2 pressed on the serial console while inserting the usb-a into
the PC (which will also power the board). boot0 from the nand will then jump
into fel mode when it sees the 2 keypress.

This was an interesting exercise to confirm that everything on the A31s just
works with A31 code, but now that is confirms A31s devices are not all that
interesting anymore :)

Ok, I'll drop it from the commit message.
