* [ARM] ARMv6: add CPU_HAS_ASID configurationRussell King2007-05-174-4/+12
| | | | | | | | | | | | Presently, we check for the minimum ARM architecture that we're building for to determine whether we need ASID support. This is wrong - if we're going to support a range of CPUs which include ARMv6 or higher, we need the ASID. Convert the checks to use a new configuration symbol, and arrange for ARMv6 and higher CPU entries to select it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] integrator: fix pci_v3 compile error with DEBUG_LLRussell King2007-05-171-0/+1
| | | | | | | | If DEBUG_LL is enabled, we want to use get_irq_regs(), but this causes a build error due to the inline function missing. Add the necessary header file. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] gic: Fix gic cascade irq handlingRussell King2007-05-171-11/+9
| | | | | | | | | | | | No need for the cascade irq function to have a "fastcall" annotation. Fix the range checking for valid IRQ numbers - comparing the value returned by the GIC with NR_IRQS is meaningless since we translate the GIC irq number to a Linux IRQ number afterwards. Check the GIC returned IRQ number is within limits first, then add the IRQ offset, and only then compare with NR_IRQS. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 4384/1: S3C2412/13 SPI registers offset correctionSandeep Sanjay Patil2007-05-164-4/+16
| | | | | | | | | | Change the SPI Channel 1 register offset in s3c_spi1_resource[], and s3c2412_dma_mappings[]. Offset has to be 0x100 in s3c2412/13's case. Also, total SPI memory resource size changed to 0x24 for s3c2412/13.

| | | | | | | | | | | | | | | WARNING: arch/arm/mach-iop13xx/built-in.o - Section mismatch: reference to .init.text:iop13xx_pcie_map_irq from .text between 'iop13xx_pci_setup' (at offset 0x7fc) and 'iop13xx_map_pci_memory' While fixing this warning I also recalled Adrian Bunk's recommendation to not use inline in .c files, as 'iop13xx_map_pci_memory' is needlessly inlined.

Rewrite mode programming code: * disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled even if both devices on the channel are not DMA capable and after reset * enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset() as they need to be setup correctly also for PIO only devices, plus IORDY wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for ATAPI devices * remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma() (driver sets ->autotune to 1 so PIO modes are always programmed => lower nibble of register A never equals 4 => "chipset_is_set" is always true) * enable PIO mode programming for all ATAPI devices (it was limited to ->media == ide_cdrom devices) * remove extra reads of registers A/B/C, don't read register D et all * do clearing / programming of registers A/B/C in one go (gets rid of extra PCI config space read/write cycle) * set initial values of drive_conf/AP/BP/CP variables to zero (paranoia for the case when PCI reads fail) * remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen (ide_rate_filter() takes care of it) * fix XFER_MW_DMA0 timings (they were overclocked, use the official ones) * fix bitmasks for clearing bits of register B: - when programming DMA mode bit 0x10 of register B was cleared which resulted in overclocked PIO timing setting (iff PIO0 was used) - when programming PIO mode bits 0x18 weren't cleared so suboptimal timings were used for PIO1-4 if PIO0 was previously set (bit 0x10) and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08) * add FIXME comment about missing locking for 66MHz clock register Also while at it: * remove unused defines * do a few cosmetic / CodingStyle fixes * bump driver version v2: * in pdc202xx_tune_chipset() the old content of drive configuration registers is used only by the debugging code so cover "drive_conf" PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO (Noticed by Sergei Shtylyov) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
