What: The arch/ppc and include/asm-ppc directories
When: Jun 2008
Why: The arch/powerpc tree is the merged architecture for ppc32 and ppc64
platforms. Currently there are efforts underway to port the remaining
arch/ppc platforms to the merged tree. New submissions to the arch/ppc
tree have been frozen with the 2.6.22 kernel release and that tree will
remain in bug-fix only mode until its scheduled removal. Platforms
that are not ported by June 2008 will be removed due to the lack of an
interested maintainer.

k) Global Utilities Block
The global utilities block controls power management, I/O device
enabling, power-on-reset configuration monitoring, general-purpose
I/O signal configuration, alternate function selection for multiplexed
signals, and clock control.
Required properties:
- compatible : Should define the compatible device type for
global-utilities.
- reg : Offset and length of the register set for the device.
Recommended properties:
- fsl,has-rstcr : Indicates that the global utilities register set
contains a functioning "reset control register" (i.e. the board
is wired to reset upon setting the HRESET_REQ bit in this register).
Example:
global-utilities@e0000 { /* global utilities block */
compatible = "fsl,mpc8548-guts";
reg = <e0000 1000>;
fsl,has-rstcr;

Select this option to enable more accurate task and CPU time
accounting. This is done by reading a CPU counter on each
kernel entry and exit and on transitions within the kernel
between system, softirq and hardirq state, so there is a
small performance impact. This also enables accounting of
stolen time on logically-partitioned systems running on
IBM POWER5-based machines.

This enables support for systems with more than one CPU. If you have

than one CPU, say Y. Note that the kernel does not currently
support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
since they have inadequate hardware support for multiprocessor
operation.
If you say N here, the kernel will run on single and multiprocessor
machines, but will use only one CPU of a multiprocessor machine. If
you say Y here, the kernel will run on single-processor machines.
On a single-processor machine, the kernel will run faster if you say
N here.
If you don't know what to do here, say N.
