This patch converts the cpu specific 7750 setup code to use the new intc controller. Many new vectors are added and multiple processor variants including 7091, 7750, 7750s, 7750r, 7751 and 7751r should all have the correct vectors hooked up. IRLM interrupts can be enabled using ipr_irq_enable_irlm() which now is marked as __init. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

|
|
kexec is a system call that implements the ability to shutdown your
|
|
current kernel, and to start another kernel. It is like a reboot
|
|
but it is independent of the system firmware. And like a reboot
|
|
you can start any kernel with it, not just Linux.
|
|
|
|
The name comes from the similarity to the exec system call.
|
|
|
|
It is an ongoing process to be certain the hardware in a machine
|
|
is properly shutdown, so do not be surprised if this code does not
|
|
initially work for you. It may help to enable device hotplugging
|
|
support. As of this writing the exact hardware interface is
|
|
strongly in flux, so no good recommendation can be made.

This allows you to specify the maximum number of CPUs which this
|
|
kernel will support. The maximum supported value is 32 and the
|
|
minimum value which makes sense is 2.
|
|
|
|
This is purely to save memory - each supported CPU adds
|
|
approximately eight kilobytes to the kernel image.

Selecting this option will wakeup the User Break Controller (UBC) on
|
|
startup. Although the UBC is left in an awake state when the processor
|
|
comes up, some boot loaders misbehave by putting the UBC to sleep in a
|
|
power saving state, which causes issues with things like ptrace().

If unsure, say N.

Find out whether you have ISA slots on your motherboard. ISA is the
|
|
name of a bus system, i.e. the way the CPU talks to the other stuff
|
|
inside your box. Other bus systems are PCI, EISA, MicroChannel
|
|
(MCA) or VESA. ISA is an older system, now being displaced by PCI;
|
|
newer boards don't support it. If you have ISA, say Y, otherwise N.

The Extended Industry Standard Architecture (EISA) bus was
|
|
developed as an open alternative to the IBM MicroChannel bus.
|
|
|
|
The EISA bus provided some of the features of the IBM MicroChannel
|
|
bus while maintaining backward compatibility with cards made for
|
|
the older ISA bus. The EISA bus saw limited use between 1988 and
|
|
1995 when it was made obsolete by the PCI bus.
|
|
|
|
Say Y here if you are building a kernel for an EISA-based machine.
|
|
|

Otherwise, say N.

MicroChannel Architecture is found in some IBM PS/2 machines and

Compact Flash is a small, removable mass storage device introduced

in 1994 originally as a PCMCIA device. If you say `Y' here, you

If your board has "Directly Connected" CompactFlash at area 5 or 6,
|
|
you may want to enable this option. Then, you can use CF as

primary IDE drive (only tested for SanDisk).

If in doubt, select 'N'.
