// This code is a hardware specific device driver for the SoRo Systems
// USB-D12-104, a PC/104 (ISA) Full-Speed USB slave board, which turns
// a PC/104 stack into a USB slave device. The board contains a
// Philips PDIUSBD12 Peripheral Controller Chip mapped into the PC's
// I/O space, with jumper-selectable I/O base address, IRQ, and DMA
// settings. The eCos config tool is used to adjust settings for this
// driver to match the physical jumper settings. The chip could run in
// polled mode without an IRQ, but this wouldn't be a great idea other
// than maybe a debug environment.
