28  * COMMENT: I-O DATA LanDisk USL-5P
29  *
30  * This machine consists of:
31  *
32  * o) An SH4 processor, which includes serial console etc,
33  * o) 64 MB RAM (at 0x0c000000),
34  * o) an IDE controller at address 0x14000000 (irq 10),
35  * o) a RS5C313 real time clock, connected to the SH4 SCI port,
36  * o) a PCI controller (PCIC),
37  * o) and a minimal SH-IPL+G PROM emulation layer (required to make
38  * OpenBSD/landisk boot).
39  *
40  * TODO:
41  * Realtek NIC (irq 5), PCIIDE (irq 6), USB controllers, etc.
42  *
43  * TODO 2:
44  * Make it possible to select different landisk models.
