|
* Interrupt routing description for the AXUS TC320 board.
|
|
* It was not possible to read back the PIRQ table. There was no BIOS to ask
|
|
* for it, only a bootloader for an embedded OS.
|
|
* But with the method described here:
|
|
* http://coreboot.org/Creating_Valid_IRQ_Tables
|
|
* it was possible to detect the physical IRQ routing on this board.
|
|
*
|
|
* This is the physical routing on this board:
|
|
*
|
|
* IRQ 5530 USB Network
|
|
* controller northbridge device device
|
|
* 00.13.0 00.0e.00
