---------------------------
What: Support for NEC DDB5476 evaluation boards.
When: June 2006
Why: Board specific code doesn't build anymore since ~2.6.0 and no
users have complained indicating there is no more need for these
boards. This should really be considered a last call.
Who: Ralf Baechle <ralf@linux-mips.org>
---------------------------
What: USB driver API moves to EXPORT_SYMBOL_GPL
When: Febuary 2008
Files: include/linux/usb.h, drivers/usb/core/driver.c

* Interrupt mapping
*
* We have three interrupt controllers:
*
* . CPU itself - 8 sources
* . i8259 - 16 sources
* . vrc5476 - 16 sources
*
* They connected as follows:
* all vrc5476 interrupts are routed to cpu IP2 (by software setting)
* all i2869 are routed to INTC in vrc5476 (by hardware connection)
*
* All VRC5476 PCI interrupts are level-triggered (no ack needed).
* All PCI irq but INTC are active low.
