XilnixFB can be used by more than just arch/ppc. Move the data structure definition into include/linux/xilinxfb.h so it can be used by microblaze and arch/powerpc Signed-off-by:

By configuring it earlier we get console output sooner which is helpful for debugging when the kernel crashes before the serial drivers are initialized. Signed-off-by:

Add of_platform bus binding so this driver can be used with arch/powerpc Signed-off-by:

Tidy the comments to split the driver into logical section; the main driver, the console driver, the platform bus binding, and module initialization and teardown. Signed-off-by:

The Uartlite data sheet defines the registers as 32 bit wide. This patch changes the register access to use 32 bit transfers and eliminates the magic +3 offset which is currently required to make the device work. Signed-off-by:

Adds support for generic Xilinx Virtex boards. Any board which specifies "xilinx,virtex" in the compatible property will make use of this board support. Signed-off-by:

Add a workaround for PowerPC 440EPx/GRx incorrect write to DDR SDRAM errata. Data can be written to wrong address in SDRAM when write pipelining enabled on plb0. We disable it in the cpu_setup for these processors at early init. Signed-off-by:

The PowerPC 440EP(x) FPU init is currently done in head_44x under ifdefs. Since we should support more then one board in the same kernel, we move FPU initialization code from head_44x to cpu_setup_44x and add cpu_setup callbacks for 440EP(x). Signed-off-by:

Valentine Barshak authored
This adds cpu_setup functionality for ppc44x platform. Low level cpu-spefic initialization routines should be placed in cpu_setup_44x.S and a callback should be added to cputable. The cpu_setup is invoked by identify_cpu() function at early init. Signed-off-by:

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). Signed-off-by:

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 adds support for the PCI bus on Celleb with new "I/O routines for PowerPC." External PCI on Celleb must do explicit synchronization with devices (Bus has no automatic synchronization feature). Signed-off-by:

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. Signed-off-by:

-
Michael Ellerman authored
In its current form, dcr_map() doesn't remember the base address you passed it, which means you need to store it somewhere else. Rather than adding the base to another struct it seems simpler to store it in the dcr_host_t. Signed-off-by:

The trick for finding the right defconfig is neat, but you forgot to provide an i686_defconfig. ;-) More seriously, cross compiling the defconfig is often useful, e.g. for testing the compilation of patches that touch multiple architectures, and this patch therefore chooses g5_defconfig if $(CROSS_COMPILE) is non-empty.
