* universe are wired to which 'lines'/inputs at the PIC.
* (consult vmeUniverse.h for more information).
*
* When installing the universe IRQ manager it is also
* possible to specify whether it should try to share
* PIC interrupts with other sources. This might not
* be supported by all BSPs (but the unverse driver
* recognizes that).
*
* If BSP_VME_INSTALL_IRQ_MGR is undefined then
* the default algorithm is used (vme_universe.c):
*
* This default setup uses only a single wire. It reads
* the PIC 'line' from PCI configuration space and assumes
* this to be wired to the first (LIRQ0) IRQ input at the
* universe. The default setup tries to use interrupt
* sharing.
