| * m68k/atari: Reserve some ST-RAM early on for device buffer useMichael Schmitz2011-07-304-298/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on an original patch from Michael Schmitz: Because mem_init() is now called before device init, devices that rely on ST-RAM may find all ST-RAM already allocated to other users by the time device init happens. In particular, a large initrd RAM disk may use up enough of ST-RAM to cause atari_stram_alloc() to resort to __get_dma_pages() allocation. In the current state of Atari memory management, all of RAM is marked DMA capable, so __get_dma_pages() may well return RAM that is not in actual fact DMA capable. Using this for frame buffer or SCSI DMA buffer causes subtle failure. The ST-RAM allocator has been changed to allocate memory from a pool of reserved ST-RAM of configurable size, set aside on ST-RAM init (i.e. before mem_init()). As long as this pool is not exhausted, allocation of real ST-RAM can be guaranteed. Other changes: - Replace the custom allocator in the ST-RAM pool by the existing allocator in the resource subsystem, - Remove mem_init_done and its hook, as memory init is now done before device init, - Remove /proc/stram, as ST-RAM usage now shows up under /proc/iomem, e.g. 005f2000-006f1fff : ST-RAM Pool 005f2000-0063dfff : atafb 0063e000-00641fff : ataflop 00642000-00642fff : SCSI Signed-off-by: Michael Schmitz <schmitz@debian.org> [Andreas Schwab <schwab@linux-m68k.org>: Use memparse()] [Geert: Use the resource subsystem instead of a custom allocator] Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

| * sparc: _sparc_find_resource() should check for exact matchesGeert Uytterhoeven2011-07-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The address that's passed to _sparc_find_resource() should always be the start address of a resource: - iounmap() passes a page-aligned virtual address, while the original address was created by adding the in-page offset to the resource's start address, - sbus_free_coherent() and pci32_free_coherent() should be passed an address obtained from sbus_alloc_coherent() resp. pci32_alloc_coherent(), which is always a resource's start address.

| | | | | | | | | | | | | | | | | | | | | | As of commit 5df1abdbd37af2ae317a1c5b5944173284dc55d6 ('m68k/amiga: Fix "debug=mem"'), "debug=mem" no longer uses amiga_chip_alloc_res(), so we can remove the hack to prefer memory at the safe end.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 6e8af08dfa40b747002207d3ce8e8b43a050d99f enables pci=bfsort on future Dell systems. But the identification string 'Dell System' matches on already existing whitelist, which do not have SMBIOS type 0xB1, causing pci=bfsort not being set on existing whitelist. This patch fixes the regression by moving the type 0xB1 check beyond the existing whitelist so that existing whitelist is walked before.

| * | x86/PCI: config space accessor functions should not ignore the segment argumentJan Beulich2011-07-225-2/+14

Apart from pci_direct_conf1, all other non-MMCFG access methods get used only for non-extended accesses (i.e. assigned to raw_pci_ops only). Consequently, with the way raw_pci_{read,write}() work, it would be a coding error to call these functions with a non-zero segment (with the current call flow this cannot happen afaict). The access method 1 accessor, as it can be used for extended accesses (on AMD systems) instead gets checks added for the passed in segment to be zero. This would be the case when on such a system having multiple PCI segments (don't know whether any exist in practice) MMCFG for some reason is not usable, and method 1 gets selected for doing extended accesses. Rather than accessing the wrong device's config space, the function will now error out. v2: Convert BUG_ON() to WARN_ON(), and extend description as per Ingo's request.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Host bridge windows are top-level resources, so if we find a host bridge window conflict, it's probably with a hard-coded legacy reservation.

We have bug before that using mmconf to access pci config space hangs system (when resizing BARs), so we use type1 config for legacy config space. 2. when doing mmconfg bar checking, we need access ACPI _CRS, which might access PCI config space.

The current code enables the gasket only when phy interface is RMII. It's broken when the driver works with a MII phy. The patch uses platform_device_id to distinguish the SoCs that have the gasket and enables it on these SoCs for both MII and RMII mode.

A couple of !cpu_is_mx1 logic gets turned into is_imx21_uart, as the codes wrapped there are really IMX21 type uart specific. It also removes macro MX1_UCR3_REF25 and MX1_UCR3_REF30 which are not used anywhere.

This patch adds a new versatile platform for when using the device tree. Add platform and amba devices are discovered and registered by parsing the device tree. Clocks and initial io mappings are still configured statically. This patch still depends on some static platform_data for a few devices which is passed via the auxdata structure to of_platform_populate(), but it is a viable starting point until the drivers can get all configuration data out of the device tree.

This is particularly important for architectures adding device tree support because the current implementation (excluding PowerPC and SPARC) cannot handle translation for more than a single interrupt controller. irq_domain supports device tree translation for any number of interrupt controllers. This patch converts x86, Microblaze, ARM and MIPS to use irq_domain for device tree irq translation. x86 is untested beyond compiling it, irq_domain is enabled for MIPS and Microblaze, but the old behaviour is preserved until the core code is modified to actually register an irq_domain yet. On ARM it works and is required for much of the new ARM device tree board support. PowerPC has /not/ been converted to use this new infrastructure. It is still missing some features before it can replace the virq infrastructure already in powerpc (see documentation on irq_domain_map/unmap for details). Followup patches will add the missing pieces and migrate PowerPC to use irq_domain. SPARC has its own method of managing interrupts from the device tree and is unaffected by this change.
