2009-02-11powerpc/pci: Move hose_list and pci_address_to_pio to pci-commonMilton Miller3-45/+36
move the definition of hose_list next to its hotplug spinlock. create pcibios_io_size to encapsulate ifdef in existing pci-common function pcibios_vaddr_is_ioport move pci_address_to_pio to pci-common, using new pcibios_io_size, and protect this GPL exported function against concurrent hotplug removal Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-02-11powerpc/pseries: Return the number of MSIs we could allocateMichael Ellerman1-7/+9
If we can't allocate the requested number of MSIs, we can still tell the generic code how many we were able to allocate. That can then be passed onto the driver, allowing it to request that many in future, and probably succeeed.

2009-02-11powerpc: Allow debugging of LMBs with lmb=debugMichael Ellerman1-5/+1
The lmb debugging can be turned on at boottime with lmb=debug on the command line. However on powerpc that doesn't work, because we don't necessarily call lmb_dump_all(). So always call lmb_dump_all() after lmb_analyze(), no output is generated unless lmb=debug is found on the command line. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: David S.

2009-02-10powerpc/pci: mmap anonymous memory when legacy_mem doesn't existBenjamin Herrenschmidt1-2/+15
The new legacy_mem file in sysfs is causing problems with X on machines that don't support legacy memory access. The way I initially implemented it, we would fail with -ENXIO when trying to mmap it, thus exposing to X that we do support the API but there is no legacy memory. Unfortunately, X poor error handling is causing it to fail to start when it gets this error. This implements a workaround hack that instead maps anonymous memory instead (using shmem if VM_SHARED is set, just like /dev/zero does).

2009-02-04powerpc/5200: Rework GPT driver to also be an IRQ controllerGrant Likely3-86/+436
This patch adds IRQ controller support to the MPC5200 General Purpose Timer (GPT) device driver. With this patch the mpc5200-gpt driver supports both GPIO and IRQ functions. The GPT driver was contained within the mpc52xx_gpio.c file, but this patch moves it out into a new file (mpc52xx_gpt.c) since it has more than just GPIO functionality now and it was only grouped with the mpc52xx-gpio drivers as a matter of convenience before. Also, this driver will most likely get extended again to also provide support for the timer function. Implementation note: Alternately, I could have tried to implement the IRQ support as a separate driver and left the GPIO portion alone. However, multiple functions of this device (ie. GPIO input+interrupt controller, or timer+GPIO) can be active at the same time and the registers are shared so it is safer to contain all functionality within a single driver.

2009-02-04powerpc/5200: Refactor mpc5200 interrupt controller driverGrant Likely1-88/+59
Rework the mpc5200-pic driver to simplify it and fix up the setting of desc->status when set_type is called for internal IRQs (so they are reported as level, not edge). The simplification is due to splitting off the handling of external IRQs into a separate block so they don't need to be handled as exceptions in the normal CRIT, MAIN and PERP paths.

2009-02-03powerpc/5200: Trim cruft from device treesGrant Likely6-314/+106
Trim out obsolete/extraneous properties and tighten up some usage conventions. Changes include: - removal of device_type properties - removal of cell-index properties - Addition of gpio-controller and #gpio-cells properties to gpio nodes - Move common interrupt-parent property out of device nodes and into top level parent node. This patch also include what looks to be just trivial editorial whitespace/format changes, but there is real method in this madness. Editorial changes were made to keep the all the mpc5200 board device trees as similar as possible so that diffs between them only show the real differences between the boards. The pcm030 device tree was most affected by this because many of the comments had been changed from // to /* */ style and some cell values where changed from decimal to hex format when it was cloned from one of the other 5200 device trees.

2009-01-30powerpc/5200: Bugfix for PCI mapping of memory and IMMRGrant Likely1-14/+10
This patch ensures that memory gets properly mapped into the PCI address space. Without this patch, the memory window BAR is left at whatever value happened to be loaded into the BAR when Linux was booted. Without this patch, memory could end up getting mapped at any of the 1G address boundaries instead of at '0' where Linux expects it. Similarly, this patch also ensures that the internally memory mapped registers (IMMR) are mapped to the correct PCI address range. Without this patch, PCI appears to work correctly until a PCI device is inserted which DMAs into memory.
