Subject: [POWERPC] Created arch/powerpc/platforms/Kconfig for "Platform
 support"

Split "Platform support" menu out from arch/powerpc/Kconfig into
arch/powerpc/platforms/Kconfig in prep for allowing other sub-arches to
be configured via a single "Platform support" menu.

+	  G3 and G4 processors have an on-chip temperature sensor called the

+	  temperature within 2-4 degrees Celsius. This option shows the current
+	  on-die temperature in /proc/cpuinfo if the cpu supports it.
+
+	  Unfortunately, on some chip revisions, this sensor is very inaccurate

+config TAU_INT
+	bool "Interrupt driven TAU driver (DANGEROUS)"
+	depends on TAU
+	---help---
+	  The TAU supports an interrupt driven mode which causes an interrupt
+	  whenever the temperature goes out of range. This is the fastest way
+	  to get notified the temp has exceeded a range. With this option off,
+	  a timer is used to re-check the temperature periodically.
+
+	  However, on some cpus it appears that the TAU interrupt hardware
+	  is buggy and can cause a situation which would lead unexplained hard
+	  lockups.
+
+	  Unless you are extending the TAU driver, or enjoy kernel/hardware
+	  debugging, leave this option off.
+
+config TAU_AVERAGE
+	bool "Average high and low temp"
+	depends on TAU
+	---help---
+	  The TAU hardware can compare the temperature to an upper and lower
+	  bound.  The default behavior is to show both the upper and lower
+	  bound in /proc/cpuinfo. If the range is large, the temperature is
+	  either changing a lot, or the TAU hardware is broken (likely on some
+	  G4's). If the range is small (around 4 degrees), the temperature is
+	  relatively stable.  If you say Y here, a single temperature value,
+	  halfway between the upper and lower bounds, will be reported in
+	  /proc/cpuinfo.
+
+	  If in doubt, say N here.

Subject: [POWERPC] QE: automatically select QE options

Change the Kconfig files so that the Freescale QE options are automatically
selected if a QE device is selected.  Previously, you'd need to manually
select UCC_FAST if you want any "fast" UCC devices, such as Gigabit Ethernet.
Now, the QE Gigabit Ethernet option is always available if the device has a
QE, and UCC_FAST is automatically enabled.  A side-effect is that the
"QE Options" menu no longer exists.

* Moved sourcing of platforms/embedded6xx/Kconfig into platform/Kconfig
* Moved sourcing of platforms/4xx/Kconfig into platform/Kconfig and disabled it
* Removed EMBEDDEDBOOT since its not supported in arch/powerpc
* Removed PC_KEYBOARD since its not used anywhere
* Moved a few CONFIG options around in platform/Kconfig
* Moved interrupt controllers into platform/Kconfig out of bus section

Subject: [POWERPC] Rename MPIC_BROKEN_U3 to MPIC_U3_HT_IRQS

Rename MPIC_BROKEN_U3 to something a little more descriptive. Its
effect is to enable support for HT irqs behind the PCI-X/HT bridge on
U3/U4 (aka. CPC9x5) parts.

Subject: [POWERPC] Clean up cpufreq Kconfig dependencies

Shuffle Kconfig order, making the platform drivers menu depend on the global
option instead of each driver being dependent on it.

Also fix dependency of PPC_PMAC on the G5 one.
