ide: cable detection fixes (take 2)
Tejun's recent eighty_ninty_three() fix has inspired me to do more thorough review of the cable detection code... * print user-friendly warning about limiting the maximum transfer speed to UDMA33 (and the reason behind it) when 80-wire cable is not detected, also while at it cleanup eighty_ninty_three() a bit * use eighty_ninty_three() in ide_ata66_check(), this actually fixes 3 bugs: - bit 14 (word 93 validity check) == 1 && bit 13 (80-wire cable test) == 1 were used as 80-wire cable present test for CONFIG_IDEDMA_IVB=n case (please see FIXME comment in eighty_ninty_three() for more details) - CONFIG_IDEDMA_IVB=y/n cases were interchanged - check for SATA devices was missing * remove private cable warnings from pdc_202xx{old,new} drivers now that core code provides this functionality (plus, in pdc202xx_new case the test could give false warnings for ATAPI devices because pdc202xx_new driver doesn't even support ATAPI DMA) Cc: Tejun Heo <htejun@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
