This introduces a new device binding for the CPM and other devices on these boards. Some of the changes include: 1. Proper namespace scoping for Freescale compatibles and properties. 2. Use compatible rather than things like device_type and model to determine which particular variant of a device is present. 3. Give the drivers the relevant CPM command word directly, rather than requiring it to have a lookup table based on device-id, SCC v. SMC, and CPM version. 4. Specify the CPCR and the usable DPRAM region in the CPM's reg property. Boards that do not require the legacy bindings should select CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once all existing boards are converted and tested, the config option can become default y to prevent new boards from using the old model. Once arch/ppc is gone, the config option can be removed altogether.

As suggested by David Gibson, now that we have a separate node for the baud rate generators, it's better to use the standard clock-frequency property than a cpm-node-level fsl,brg-frequency property. This patch updates existing places where fsl,brg-frequency is used. Signed-off-by: NScott Wood <scottwood@freescale.com> Signed-off-by: NKumar Gala <galak@kernel.crashing.org>

Commit 8112753b made 44x in ARCH=powerpc builds use cpu setup routines in cpu_setup_44x.S, but didn't make a similar change for ARCH=ppc, and consequently the ARCH=ppc builds fail with undefined symbols (since both use the same cputable.c). This fixes it by including cpu_setup_44x.S in the ARCH=ppc builds, and by taking out the now-redundant FPU initialization in arch/ppc/kernel/head_44x.S.

Reverts commit a15da8ef This driver is used by devices other than the xilinx opb-uartlite which depend on bytewise access to the registers. The change to 32 bit access does not work on these devices.

The Uartlite data sheet defines the registers as 32 bit wide.

The PowerPC 440EP(x) FPU init is currently done in head_44x under ifdefs.

This registers a clock event structure for the decrementer and turns on CONFIG_GENERIC_CLOCKEVENTS, which means that we now don't need most of timer_interrupt(), since the work is done in generic code. For secondary CPUs, their decrementer clockevent is registered when the CPU comes up (the generic code automatically removes the clockevent when the CPU goes down).

Some older pSeries machines were panicking in pSeries_log_error because it was getting called before it was ready. This is a result of commit "[POWERPC] pseries: Fix jumbled no_logging flag." (79c0108d). This fixes it by explicitly enabling RTAS error logging when it has been initialized, and also makes the code clearer by renaming the "no_more_logging" variable to "logging_enabled".

This supports Power/Reset buttons on Beat on Celleb. On Beat, we have an event from Beat if Power button or Reset button is pressed. This patch catches the event and convert it to a signal to INIT process by calling ctrl_alt_del() function. /sbin/inittab have no entry to turn the machine power off so we have to detect if power button is pressed or not internally in our driver. This idea is taken from PS3's event handling subsystem.
