Revision 3a38d437

ID3a38d437ca60ce19ee92dbabbe6e672e9ba3c529

Added by Jes Sorensen about 12 years ago

Add isa_reserve_irq().

Introduce isa_reserve_irq() which marks an irq reserved and returns
the appropriate qemu_irq entry from the i8259 table.

isa_reserve_irq() is a temporary interface to be used to allocate ISA
IRQs for devices which have not yet been converted to qdev, and for
special cases which are not suited for qdev conversions, such as the
'ferr'.

This patch goes on top of Gerd Hoffmann's which makes isa-bus.c own
the ISA irq table.

[ added isa-bus.o to some targets to fix build failures -- kraxel ]
