This patch fixes a numbers of issues regarding to that both 8xx and 82xx
began to use ppc_sys model:
- Platform is now identified by default deviceless SOC, if no
BOARD_CHIP_NAME is specified in the bard-specific header. For the list
of supported names refer to (arch/ppc/syslib/) mpc8xx_sys.c and
mpc82xx_sys.c for 8xx and 82xx respectively.
- Fixed a bug in identification by name - if the name was not found,
it returned -1 instead of default deviceless ppc_spec.
- fixed devices amount in the 8xx platform system descriptions

Convert core 8xx drivers to use in_xxxbe/in_xxx macros instead of direct
memory references.
Other than making IO accesses explicit (which is a plus for readability), a
common set of macros provides a unified place for the volatile flag to
constraint compiler code reordering.
There are several unlucky places at the moment which lack the volatile
flag.

This changes the parameters for i8259_init so that it takes two
parameters: a physical address for generating an interrupt
acknowledge cycle, and an interrupt number offset. i8259_init
now sets the irq_desc[] for its interrupts; all the callers
were doing this, and that code is gone now. This also defines
a CONFIG_PPC_I8259 symbol to select i8259.o for inclusion, and
makes the platforms that need it select that symbol.

This makes platform code use the smp_ops variable directly instead

This fixes up a variety of minor problems in compiling with ARCH=ppc
arising from using the merged versions of various header files.
A lot of the changes are just adding #include <asm/machdep.h> to
files that use ppc_md or smp_ops_t.
This also arranges for us to use semaphore.c, vecemu.c, vector.S and
fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc.

Now instead of having a ppc_md function, we just have a variable
which says whether to do the i8259 irq canonicalization or not,
and set that variable on the platforms that need that. It looks
to me that radstone_ppc7d was trying to use irq canonicalization
for something else in a broken kind of way - it will need to be
fixed properly.

This creates the directory structure under arch/powerpc and a bunch
of Kconfig files. It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.
For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes
to files in those directories and files outside arch/powerpc.
The boot directory is still not merged. That's going to be interesting.

The SMU is the "system controller" chip used by Apple recent G5 machines
including the iMac G5. It drives things like fans, i2c busses, real time
clock, etc...
The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously. This is a completely
rewritten driver that provides interrupt based command queuing, a userland
interface, and an i2c/smbus driver for accessing the devices hanging off
the SMU i2c busses like temperature sensors. This driver is a basic block
for upcoming work on thermal control for those machines, among others.

of comparison.

PowerPC 40x and Book-E processors support a watchdog timer at the processor
core level. The timer has implementation dependent timeout frequencies
that can be configured by software.
One the first Watchdog timeout we get a critical exception. It is left to
board specific code to determine what should happen at this point. If
nothing is done and another timeout period expires the processor may
attempt to reset the machine.
Command line parameters:
wdt=0 : disable watchdog (default)
wdt=1 : enable watchdog
wdt_period=N : N sets the value of the Watchdog Timer Period.
The Watchdog Timer Period meaning is implementation specific. Check
User Manual for the processor for more details.
This patch is based off of work done by Takeharu Kato.
