Describe: Support PDC20268, PDC20269, PDC20275(ATA-100/133 Controllers)
Support Ultra-DMA Mode 6. Maxtor 48-bit LBA spec.
Changes:
/usr/src/linux/drivers/ide/ide-disk.c
ide_startstop_t do_rw_disk()
* if drives support LBA48 and UDMA then prepare 48bit data for UDMA.
* if drives support LBA48 then issue 48bit command for PIO.
init_idedisk_capacity()
* if drives support LBA48 then read current maximal capacity.
/usr/src/linux/drivers/ide/ide-dma.c
report_drive_dmaing()
config_drive_for_dma()
* fix UltraDMA mode 6 selectable
ide_dmaproc()
* if drives support LBA48 and DMA then issue 48bit command for DMA
* if PDC20262/65/67 through ATAPI UDMA
/usr/src/linux/drivers/ide/ide-features.c
eighty_ninty_three()
* fix some hard drivers ATA-66 support response.
/usr/src/linux/drivers/ide/ide.c
ide_dump_status()
* return error 48bit LBA address if running 48bit LBA
/usr/src/linux/drivers/ide/ide-pci.c
* add PDC20268/69/75 controllers structure
/usr/src/linux/drivers/ide/pdc202xx.c
pdc202xx_info()
* fix proc information report
pdc202xx_tune_chipset()
* fix set-speed from PDC20262/65/67 and PDC20268/69/75
because the rule is different.
config_chipset_for_dma()
* support UDMA 6 selectable
* check is 80pin cable, if no will down to UDMA 2.
* fix some control rule for PDC20262/65/67 and PDC20268/69/75
ata66_pdc202xx()
* fix judge 80pin cable
pdc202xx_reset()
pci_init_pdc202xx()
* add PDC20268/69/75 controllers routine.
/usr/src/linux/include/linux/pci_ids.h
* add PROMISE IDE controllers device IDs
