This patch adds support for the power button on future IBM cell blades.
It actually doesn't shut down the machine. Instead it exposes an
input device /dev/input/event0 to userspace which sends KEY_POWER
if power button has been pressed.
haldaemon actually recognizes the button, so a plattform independent acpid
replacement should handle it correctly.

This patch adds a cpufreq governor that takes the number of running spus
into account. It's very similar to the ondemand governor, but not as complex.
Instead of hacking spu load into the ondemand governor it might be easier to
have cpufreq accepting multiple governors per cpu in future.
Don't know if this is the right way, but it would keep the governors simple.

This reverts commit e3621ee6.

This was not the proper fix.  As Scott Wood said CONFIG_FS_ENET has nothing
to do with the issue.  The proper fix is to select PHYLIB for this board.

Its possible to build the phylib as a module, however this breaks the
board code because alloc_mdio_bitbang and mdiobus_register are not
available if we build as a module.  These are needed by the board code
since it implements the low level mdio bitbang ops.

So we unconditionally select PHYLIB to ensure its built into the kernel
if we are building in EP8248E support.

Long term we should look at moving the mdio_ops into its own file so it
can be built as a module.

This converts the FSL Book-E PTE access and TLB miss handling to match

tries to fixup write permission, this is left to generic code, and

- Get rid of uses_fsl_uli_m1575, it does not scale for all cases.
  Instead, let's explicitly use machine_is() for each fixup.
- Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with
  machine_is(). One step closer to multiplatform kernels.
- Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied.
- RTC quirk applies to all boards though, so no machine_is() checks.

This patch fixes RTC on MPC8572DS boards: dummy read helps only when
reading at the end of the bridge's memory (i.e. outside of behind the
bridge devices' assigned regions).

With this change the quirk also makes RTC work on MPC8610HPCD, so it's
unlikely that this will break MPC8641HPCN or MPC8544DS boards.

Choosing PCI or not at config time is allowed on some
platforms via an if expression in arch/powerpc/Kconfig.
To add a new platform with PCI support selectable at
config time, you must change the if expression.  This
patch makes this easier by changing:
    bool "PCI support" if <long expression>
to
    bool "PCI support" if PPC_PCI_CHOICE
and adding select PPC_PCI_CHOICE to all the config nodes that
were previously in the PCI if expression.

Platforms with unconditional PCI support continue to
just select PCI in their config nodes.

most of the other modern eval boards have.  We need this

Also remove the old, redundant chosen node.  Of all the modern
Freescale eval boards (incl. 83xx, 85xx, 86xx) this is the only
