2008-07-25gpiolib: allow user-selectionMichael Buesch1-1/+1
This patch adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.

2008-07-24ide-generic: remove ide_default_{io_base,irq}() inlines (take 3)Bartlomiej Zolnierkiewicz1-28/+0
Replace ide_default_{io_base,irq}() inlines by legacy_{bases,irqs}[]. v2: Add missing zero-ing of hws[] (caught during testing by Borislav Petkov). v3: Fix zero-oing of hws[] for _real_ this time. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <[email protected]>
2008-07-24ide: define MAX_HWIFS in <linux/ide.h>Bartlomiej Zolnierkiewicz1-8/+0
* Now that ide_hwif_t instances are allocated dynamically the difference between MAX_HWIFS == 2 and MAX_HWIFS == 10 is ~100 bytes (x86-32) so use MAX_HWIFS == 10 on all archs except these ones that use MAX_HWIFS == 1. * Define MAX_HWIFS in <linux/ide.h> instead of <asm/ide.h>. [ Please note that avr32/cris/v850 have no <asm/ide.h> and alpha/ia64/sh always define CONFIG_IDE_MAX_HWIFS. ] Signed-off-by: Bartlomiej Zolnierkiewicz <[email protected]>
2008-07-24ide-generic: remove "no_pci_devices()" quirk from ide_default_io_base()Bartlomiej Zolnierkiewicz1-14/+4
Since the decision to probe for ISA ide2-6 is now left to the user "no_pci_devices()" quirk is no longer needed and may be removed. Signed-off-by: Bartlomiej Zolnierkiewicz <[email protected]>
2008-07-24ide-generic: minor fix for mipsBartlomiej Zolnierkiewicz1-2/+0
Move ide_probe_legacy() call to ide_generic_init() so it fails early if necessary and returns the proper error value (nowadays ide_default_io_base() is used only by ide-generic). Cc: Ralf Baechle <[email protected]> Signed-off-by: Bartlomiej Zolnierkiewicz <[email protected]>
2008-04-28[MIPS] make fallback gpio.h gpiolib-friendlyAtsushi Nemoto1-0/+6

2008-04-18ide: remove ide_init_default_irq() macroBartlomiej Zolnierkiewicz1-6/+0
* Use ide_default_irq() instead of ide_init_default_irq() in ide_generic host driver (so the correct IRQ is always set regardless of CONFIG_PCI / CONFIG_BLK_DEV_IDEPCI). * Remove no longer needed ide_init_default_irq() macro. Signed-off-by: Bartlomiej Zolnierkiewicz <[email protected]>
2008-04-18ide: remove ide_default_io_ctl() macroBartlomiej Zolnierkiewicz1-2/+0
It is always == '((base) + 0x206)' if CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS=y and it is not needed otherwise (arm, blackfin, parisc, ppc64, sh, sparc[64]). Signed-off-by: Bartlomiej Zolnierkiewicz <[email protected]>
2008-04-18ide: add CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS (take 2)Bartlomiej Zolnierkiewicz1-2/+0
* Add CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS to drivers/ide/Kconfig and use it instead of defining IDE_ARCH_OBSOLETE_DEFAULTS in <arch/ide.h>. v2: * Define ide_default_irq() in ide-probe.c/ns87415.c if not already defined and drop defining ide_default_irq() for CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS=n.

2007-11-02[MIPS] Fix and cleanup the MIPS part of the (ab)use of CLOCK_TICK_RATE.Ralf Baechle1-13/+0
This is the clock rate of the i8253 PIT. A MIPS system may not have a PIT by the symbol is used all over the kernel including some APIs. So keeping it defined to the number for the PIT is the only sane thing for now. Signed-off-by: Ralf Baechle <[email protected]>

2007-07-10[MIPS] Make ioremap() work on TX39/49 special unmapped segmentAtsushi Nemoto1-0/+11
TX39XX and TX49XX have "reserved" segment in CKSEG3 area. 0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on TX39XX are reserved (unmapped, uncached). Controllers on these SoCs are placed in this segment. This patch add plat_ioremap() and plat_iounmap() to override default behavior and implement these hooks for TX39/TX49.

2007-07-10[MIPS] Make PAGE_OFFSET aware of PHYS_OFFSETFranck Bui-Huu1-1/+1
For platforms that use PHYS_OFFSET and do not use a mapped kernel, this patch automatically adds PHYS_OFFSET into PAGE_OFFSET. Therefore there are no more needs for them to redefine PAGE_OFFSET. For mapped kernel, they need to redefine PAGE_OFFSET anyways. Signed-off-by: Franck Bui-Huu <[email protected]> Signed-off-by: Ralf Baechle <[email protected]>
2007-07-10[MIPS] Clean up asm-mips/mach-generic/spaces.hFranck Bui-Huu1-38/+27
PAGE_OFFSET definition is now using CAC_BASE by default. This patch also reorder some macros to make them appear in the same order for both 32 and 64 bits configs. It also makes use of const.h generic header file to annotate constants. Signed-off-by: Franck Bui-Huu <[email protected]> Signed-off-by: Ralf Baechle <[email protected]>
2007-07-10[MIPS] Allow generic spaces.h to be included by platform specific onesFranck Bui-Huu1-0/+18
Before this patch, when a platform needed to customize one constant in spaces.h, they need to redefine all of them. Now they can just redefine one constant and include the generic file header at the end: #include <asm/mach-generic/spaces.h> This patch doesn't allow to redefine CAC_BASE, IO_BASE and UNCAC_BASE for 32 bits platforms because there's no need to do so. This will avoid some macro duplications. It's important specially if we'll add complex macros.

2007-02-13[MIPS] Unify dma-{coherent,noncoherent.ip27,ip32}Ralf Baechle2-0/+44
Platforms will now have to supply a function dma_device_is_coherent which returns if a particular device participates in the coherence domain. For most platforms this function will always return 0 or 1. Signed-off-by: Ralf Baechle <[email protected]>
2007-02-06[MIPS] Make I8259A_IRQ_BASE customizableAtsushi Nemoto1-0/+6
Move I8259A_IRQ_BASE from asm/i8259.h to asm/mach-generic/irq.h and make it really customizable. And remove I8259_IRQ_BASE declared on some platforms. Currently only NEC_CMBVR4133 is using custom I8259A_IRQ_BASE value. Signed-off-by: Atsushi Nemoto <[email protected]> Signed-off-by: Ralf Baechle <[email protected]>
2007-02-06[MIPS] Define MIPS_CPU_IRQ_BASE in generic headerAtsushi Nemoto1-0/+26
The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all platforms and are same value on most platforms (0 or 16, depends on CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make them customizable. This will save a few cycle on each CPU interrupt. A good side effect is removing some dependencies to MALTA in generic SMTC code. Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing them might cause some header dependency problem and there seems no good reason to customize it. So currently only VR41XX is using custom MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259. Testing this patch on those platforms is greatly appreciated. Thank you.

1. Move ioswab*() and __mem_ioswab*() to mangle-port.h. This gets rid of CONFIG_SGI_IP22 from include/asm-mips/io.h. 2. Pass a virtual address to *ioswab*(). Then we can provide mach-specific *ioswab*() and can do every evil thing based on its argument. It could be useful on machines which have regions with different endian conversion scheme. 3. Call __swizzle_addr*() _after_ adding mips_io_port_base. This unifies the meaning of the argument of __swizzle_addr*() (always virtual address). Then mach-specific __swizzle_addr*() can do every evil thing based on the argument. Signed-off-by: Atsushi Nemoto <[email protected]> Signed-off-by: Ralf Baechle <[email protected]>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
