For as long as the IOAPIC and LOAPIC code is coupled (as it currently is), enabling LOAPIC must select IOAPIC to be enabled as well. If future commits separate the two, then the "select IOAPIC" can be dropped. Change-Id: Ibe7e6b86e5add19b8b3cc68ebecce760d8914c86 Signed-off-by: Peter Mitsis <peter.mitsis@windriver.com>

This option selects local APIC as the interrupt controller.

This option signifies that the target has an IO-APIC device. This
|
|
capability allows IO-APIC-dependent code to be included.

help
|
|
The ARCv2 interrupt unit has 16 allocated exceptions associated with
|
|
vectors 0 to 15 and 240 interrupts associated with vectors 16 to 255.
|
|
The interrupt unit is optional in the ARCv2-based processors. When
|
|
building a processor, you can configure the processor to include an
|
|
interrupt unit. The ARCv2 interrupt unit is highly programmable.
