* [AVR32] Define ioremap_nocache, ioport_map and ioport_unmapHaavard Skinnemoen2007-02-16
| | | | | | | These are all defined in terms of ioremap/iounmap since port I/O isn't really different from memory-mapped I/O on AVR32. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Fix prototypes for __raw_writesb and friendsHaavard Skinnemoen2007-02-16
| | | | | | | The first parameter to __raw_writes[bwl] and __raw_reads[bwl] should be a void __iomem *, not unsigned long. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* sata_vsc: use default cache line size if non-zeroNate Dailey2007-02-15
| | | | | | | | | | | | | | | This modifies drivers/ata/sata_vsc.c to only set the cache line size to 0x80 if the default value is zero. Apparently zero isn't allowed due to a bug in the chip, but I've found performance is much better with the (non-zero) default instead of 0x80.

* sata_nv: handle SError status indicationRobert Hancock2007-02-15
| | | | | | | | | ADMA-capable controllers provide a bit in the status register that appears to indicate that the controller detected an SError condition. Update sata_nv to detect this and trigger error handling in order to handle the fault. Signed-off-by: Robert Hancock <hancockr@shaw.ca> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* add delay around sl82c105_reset_engine callsOlaf Hering2007-02-15
| | | | | | | | | | | The hald media changed polling does really confuse things. Noone knows why the delays are needed, but they give us access to the CD. An udelay(50) will give reliable access to the drive, but there is still one (or more) EH reset. The drive works without EH resets with udelay(100).

* ATA convert GSI to irq on ia64Zhang, Yanmin2007-02-15
| | | | | | | | | | | If an ATA drive uses legacy mode, ata driver will choose 14 and 15 as the fixed irq number. On ia64 platform, such numbers are GSI and should be converted to irq vector. Below patch against kernel 2.6.20 fixes it. Signed-off-by: Zhang Yanmin <yanmin.zhang@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* libata: clear TF before IDENTIFYingTejun Heo2007-02-15
| | | | | | | | | | | | | | Some devices chock if Feature is not clear when IDENTIFY is issued. Set ATA_TFLAG_ISADDR | ATA_TFLAG_DEVICE for IDENTIFY such that whole TF is cleared when reading ID data. Kudos to Art Haas for testing various futile patches over several months and Mark Lord for pointing out the fix.

* libata: fix drive side 80c cable check, take 3Tejun Heo2007-02-15
| | | | | | | | | | | The 80c wire bit is bit 13, not 14. Bit 14 is always 1 if word93 is implemented. This increases the chance of incorrect wire detection especially because host side cable detection is often unreliable and we sometimes soley depend on drive side cable detection. Fix the test and add word93 validity check. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* sata_promise: new EH conversion for 20619 chips, take 2Mikael Pettersson2007-02-15
| | | | | | | | | | | | | | | | | | | This patch updates the sata_promise driver to use new-style libata error handling for 20619 (TX4000) chips. sata_promise already uses new EH for the other chips it supports, so the patch is quite simple: * remove ->phy_reset and ->eng_timeout ops from pdc_pata_ops, and instead bind ->freeze, ->thaw, ->error_handler, and ->post_internal_cmd to existing new EH functions * drop ATA_FLAG_SRST from board_20619's flags * remove now unused pdc_pata_phy_reset() and pdc_eng_timeout() Tested on a TX4000 with both modern working disks and old/quirky disks. Also used a CD-RW drive to test reading and writing CDs. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| * sh: SH-DMAC compile fixesManuel Lauss2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does the following: - remove the make_ipr_irq stuff from dma-sh.c and replace it with a simple channel<->irq mapping table. - add DMTEx_IRQ constants for sh4 cpus - fix sh7751 DMAE irq number The SH7780 uses the same IRQs for DMA as other SH4 types, so I put the constants on top of the dma.h file. Other CPU types need to #define their own DMTEx_IRQ contants in their appropriate header. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Don't set reserved _PAGE_WT bit on SH-3.Paul Mundt2007-02-12
| | | | | | | | | | | | | | | | Only SH-4 needs to set _PAGE_WT when using write-through caching, don't attempt to set it on SH-3 where it ends up being a reserved bit. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Lazy dcache writeback optimizations.Paul Mundt2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts the lazy dcache handling to the model described in Documentation/cachetlb.txt and drops the ptep_get_and_clear() hacks used for the aliasing dcaches on SH-4 and SH7705 in 32kB mode. As a bonus, this slightly cuts down on the cache flushing frequency. With that and the PTEA handling out of the way, the update_mmu_cache() implementations can be consolidated, and we no longer have to worry about which configuration the cache is in for the SH7705 case. And finally, explicitly disable the lazy writeback on SMP (SH-4A). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: allow earlyprintk baud rate to be set via command lineJamie Lenehan2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows the baud rate for earlyprintk for sh4 without the standard BIOS to be set via the command line. This uses the same format as i386 and x86_64, which is: earlyprintk=serial,ttySC1,38400 The second parameter (ttySC1 above) is usually the console device name or the io address of the serial port. I allow that to be specified but ignore it in order to keep the format the same as i386/x86_64. Signed-off-by: Jamie Lenehan <lenehan@twibble.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Use a jump call table for debug trap handlers.Paul Mundt2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This rips out most of the needlessly complicated sh_bios and kgdb trap handling, and forces it all through a common fast dispatch path. As more debug traps are inserted, it's important to keep them in sync for all of the parts, not just SH-3/4. As the SH-2 parts are unable to do traps in the >= 0x40 range, we restrict the debug traps to the 0x30-0x3f range on all parts, and also bump the kgdb breakpoint trap down in to this range (from 0xff to 0x3c) so it's possible to use for nommu. Optionally, this table can be padded out to catch spurious traps for SH-3/4, but we don't do that yet.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
