| | | | | | | | | | | | | | | | | | intc_get_pending() returns a bitmask with pending interrupts in a interrupt controller group (irq).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The macb driver will probe for the PHY chip and read the mac address from the MACB registers, so we don't need them in eth_platform_data anymore. Since u-boot doesn't currently initialize the MACB registers with the mac addresses, the tag parsing code is kept but instead of sticking the information into eth_platform_data, it uses it to initialize the MACB registers (in case the boot loader didn't do it.) This code should be unnecessary at some point in the future. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| * | [POWERPC] Generic BUG for powerpcJeremy Fitzhardinge2006-12-116-92/+29

The biggest reports the function name, since it is redundant with kallsyms, and not needed in general. There is an overall reduction of code, since module_32/64 duplicated several functions. Unfortunately there's no way to tell gcc that BUG won't return, so the BUG macro includes a goto loop. This will generate a real jmp instruction, which is never used.

Its MSR[FP] is grounded to zero. If an attempt is made to execute a floating point instruction (including floating-point load, store, or move instructions), the e300c2 takes a floating-point unavailable interrupt. This patch adds support for FP emulation on the e300c2 by declaring a new CPU_FTR_FP_TAKES_FPUNAVAIL, where FP unavail interrupts are intercepted and redirected to the ProgramCheck exception path for correct emulation handling. (If we run out of CPU_FTR bits we could look to reclaim this bit by adding support to test the cpu_user_features for PPC_FEATURE_HAS_FPU instead) It adds a nop to the exception path for 32-bit processors with a FPU.

| * | | [POWERPC] Fix irq routing on some 32-bit PowerMacsBenjamin Herrenschmidt2006-12-111-45/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changes to use pci_read_irq_line() broke interrupt parsing on some 32-bit powermacs (oops). The reason is a bit obscure. The code to parse interrupts happens earlier now, during pcibios_fixup() as the PCI bus is being probed. However, the current implementation pci_device_to_OF_node() for 32-bit powerpc relies, on machines like PowerMac which renumber PCI buses, on a table called pci_OF_bus_map containing a map of bus numbers between the kernel and the firmware which is setup only later. Thus, it fails to match the device node. In addition, some of Apple internal PCI devices lack a proper PCI_INTERRUPT_PIN, thus preventing the fallback mapping code to work. This patch fixes it by making pci_device_to_OF_node() 32-bit implementation use a different algorithm that works without using the pci_OF_bus_map thing (which I intend to deprecate anyway). It's a bit slower but that function isn't called in any hot path hopefully. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

This adds the code to the kernel to parse this alternative representation. The other part of this patch is telling the firmware that we can handle the alternative representation. There is however a subtlety here, because the firmware will invoke a reboot if the memory representation we request is different from the representation that firmware is currently using. This is because firmware can't change the representation on the fly. Further, some firmware versions used on POWER5+ machines have a bug where this reboot leaves the machine with an altered value of load-base, which will prevent any kernel booting until it is reset to the normal value (0x4000). Because of this bug, we do NOT set fake_elf.rpanote.new_mem_def = 1, and thus we do not request the new representation on POWER5+ and earlier machines. We do request the new representation on POWER6, which uses the ibm,client-architecture-support call. Signed-off-by: Paul Mackerras <paulus@samba.org>
| * | | [POWERPC] dont allow pSeries_probe to succeed without initialising MMUAnton Blanchard2006-12-091-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pSeries_probe can decide that we are a pseries but then fail to initialise the MMU. If an rtas node doesnt exist, we continually fall out of pSeries_probe_hypertas early and never get to the MMU init code. While pseries without RTAS is an illegal combination, the way we currently fail is a pain to track down, and can happen if your flattened device tree code has issues (like mine did :). With the following patch we init the MMU, come up and print some warnings about RTAS not existing, instead of looping on 0x400 exceptions.

This attempts to fix it as well as possible. The rule is supposed to be that pci_resource_to_user() always converts the resources back into a BAR values since that's what the /proc interface was supposed to deal with. However, for X to work on platforms where PCI MMIO is not mapped 1:1, it became a habit of platforms like powerpc to pass "fixed up" values there since X expects to be able to use values from /proc/bus/pci/devices as offsets to mmap of /dev/mem... So we keep that contraption here, causing also /sys/*/resource to expose fully absolute MMIO addresses instead of BAR values, which is ugly, but should still work as long as those are only used to calculate alignment within a page. X is still broken when built 32 bits on machines where PCI MMIO can be above 32-bit space unfortunately.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move pSeries_mach_cpu_die() into platforms/pseries/hotplug-cpu.c, this allows rtas_stop_self() to be static so remove the prototype. Wire up pSeries_mach_cpu_die() in the initcall, rather than statically in setup.c, the initcall will still run prior to the cpu hotplug code being callable, so there should be no change in behaviour.

Do the rtas token initialisation in a new initcall, rather than rtas_initialize().

* | | [MIPS] paging_init(): use highend_pfn/highstart_pfnFranck Bui-Huu2006-12-121-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes paging_init() use highend_pfn/highstart_pfn globals. It removes the need of 'high' local which was needed only by HIGHMEM config. More important perhaps, it fixes a bug when HIGHMEM is set but there's actually no physical highmem (highend_pfn = 0) Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
