ide: remove obsoleted "idex=base[,ctl[,irq]]" kernel parameters (take 2)
* Remove obsoleted "idex=base[,ctl[,irq]]" kernel parameters and update Documentation/ide/ide.txt. * Remove no longer needed ide_forced chipset type. v2: * is_chipset_set[] -> is_chipset_set in ide.c. * Documentation/ide/ide.txt fix. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

74For special cases, interfaces may be specified using kernel "command line"
75options. For example,
76
77 ide3=0x168,0x36e,10 /* ioports 0x168-0x16f,0x36e, irq 10 */
78
79Normally the irq number need not be specified, as ide.c will probe for it:
80
81 ide3=0x168,0x36e /* ioports 0x168-0x16f,0x36e */
82
83The standard port, and irq values are these:
84
85 ide0=0x1f0,0x3f6,14
86 ide1=0x170,0x376,15
87 ide2=0x1e8,0x3ee,11
88 ide3=0x168,0x36e,10

90Note that the first parameter reserves 8 contiguous ioports, whereas the
91second value denotes a single ioport. If in doubt, do a 'cat /proc/ioports'.

93In all probability the device uses these ports and IRQs if it is attached
94to the appropriate ide channel. Pass the parameter for the correct ide
95channel to the kernel, as explained above.
