2007-10-03[POWERPC] Setup default eth addr in embed_config for Xilinx Virtex platformsGrant Likely1-0/+8
This simply adds the boilerplate default Ethernet address to embed_config for the Xilinx platform (bug fix). Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

2007-10-03[POWERPC] 4xx: 440EPx/GRx incorrect write to DDR SDRAM errata workaroundValentine Barshak2-1/+27
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: Valentine Barshak <vbarshak@ru.mvista.com> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
2007-10-03[POWERPC] 4xx: Move 440EP(x) FPU setup from head_44x to cpu_setup_4xxValentine Barshak3-10/+20
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).

2007-10-03[POWERPC] 4xx: Introduce cpu_setup functionality to 44x platformValentine Barshak3-6/+27
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: Valentine Barshak <vbarshak@ru.mvista.com> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

2007-10-03[POWERPC] Implement clockevents driver for powerpcTony Breeds4-43/+94
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).

2007-10-03[POWERPC] Fix panic in RTAS codeTony Breeds1-6/+9
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." (79c0108d1b9db4864ab77b2a95dfa04f2dcf264c). 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".

2007-10-03[POWERPC] Celleb: update for PCIIshizaki Kou8-47/+396

2007-10-03[POWERPC] Celleb: Support for Power/Reset buttonsIshizaki Kou1-1/+93
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.

2007-10-03[POWERPC] Store the base address in dcr_host_tMichael Ellerman3-4/+10
In its current form, dcr_map() doesn't remember the base address you passed it, which means you need to store it somewhere else.

2007-10-03[POWERPC] Select proper defconfig for crosscompilesAdrian Bunk1-0/+4
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.

2007-10-03[POWERPC] ppc64: support CONFIG_DEBUG_PREEMPTHugh Dickins6-5/+16
Add CONFIG_DEBUG_PREEMPT support to ppc64: it was useful for testing get_paca() preemption. Cheat a little, just use debug_smp_processor_id() in the debug version of get_paca(): it contains all the right checks and reporting, though get_paca() doesn't really use smp_processor_id(). Use local_paca for what might have been called __raw_get_paca(). Silence harmless warnings from io.h and lparcfg.c with local_paca - it is okay for iseries_lparcfg_data to be referencing shared_proc with preemption enabled: all cpus should show the same value for shared_proc. Why do other architectures need TRACE_IRQFLAGS_SUPPORT for DEBUG_PREEMPT? I don't know, ppc64 appears to get along fine without it.

2007-10-03[POWERPC] Make instruction dumping work in real modeScott Wood1-0/+8
On non-book-E, exceptions execute in real mode. If a fault happens that leads to a register dump, the kernel currently prints XXXXXXXX because it doesn't realize that PC is a physical address.

2007-10-03[POWERPC] Fix pci domain detectionArnd Bergmann1-1/+1
The /proc/bus/pci/* files list PCI domain numbers only for devices that claim to be on a multi-domain system. The check for this is broken on powerpc, because the buid value is truncated to 32 bits. There is at least one machine (IBM QS21) that only uses the high-order bits of the buid, so the return value of pci_proc_domain() ends up being always zero, which makes /proc/bus/pci useless. Change the logic to always return '1' for a nonzero buid value.

This is already done for native-bitwidth PTRACE_PEEKUSR, but was omitted for many other cases (32-bit ptrace, PTRACE_GETREGS, etc.); I think there may have been more uniform checks before that were lost in the recent cleanup of GETREGS et al.
