Currently this function knows 686a and 8231 chips.
Format: [spp|ps2|epp|ecp|ecpepp]
+ pata_legacy.all= [HW,LIBATA]
+ Format: <int>
+ Set to non-zero to probe primary and secondary ISA
+ port ranges on PCI systems where no PCI PATA device
+ has been found at either range. Disabled by default.
+
+ pata_legacy.autospeed= [HW,LIBATA]
+ Format: <int>
+ Set to non-zero if a chip is present that snoops speed
+ changes. Disabled by default.
+
+ pata_legacy.ht6560a= [HW,LIBATA]
+ Format: <int>
+ Set to 1, 2, or 3 for HT 6560A on the primary channel,
+ the secondary channel, or both channels respectively.
+ Disabled by default.
+
+ pata_legacy.ht6560b= [HW,LIBATA]
+ Format: <int>
+ Set to 1, 2, or 3 for HT 6560B on the primary channel,
+ the secondary channel, or both channels respectively.
+ Disabled by default.
+
+ pata_legacy.iordy_mask= [HW,LIBATA]
+ Format: <int>
+ IORDY enable mask. Set individual bits to allow IORDY
+ for the respective channel. Bit 0 is for the first
+ legacy channel handled by this driver, bit 1 is for
+ the second channel, and so on. The sequence will often
+ correspond to the primary legacy channel, the secondary
+ legacy channel, and so on, but the handling of a PCI
+ bus and the use of other driver options may interfere
+ with the sequence. By default IORDY is allowed across
+ all channels.
+
+ pata_legacy.opti82c46x= [HW,LIBATA]
+ Format: <int>
+ Set to 1, 2, or 3 for Opti 82c611A on the primary
+ channel, the secondary channel, or both channels
+ respectively. Disabled by default.
+
+ pata_legacy.opti82c611a= [HW,LIBATA]
+ Format: <int>
+ Set to 1, 2, or 3 for Opti 82c465MV on the primary
+ channel, the secondary channel, or both channels
+ respectively. Disabled by default.
+
+ pata_legacy.pio_mask= [HW,LIBATA]
+ Format: <int>
+ PIO mode mask for autospeed devices. Set individual
+ bits to allow the use of the respective PIO modes.
+ Bit 0 is for mode 0, bit 1 is for mode 1, and so on.
+ All modes allowed by default.
+
+ pata_legacy.probe_all= [HW,LIBATA]
+ Format: <int>
+ Set to non-zero to probe tertiary and further ISA
+ port ranges on PCI systems. Disabled by default.
+
+ pata_legacy.probe_mask= [HW,LIBATA]
+ Format: <int>
+ Probe mask for legacy ISA PATA ports. Depending on
+ platform configuration and the use of other driver
+ options up to 6 legacy ports are supported: 0x1f0,
+ 0x170, 0x1e8, 0x168, 0x1e0, 0x160, however probing
+ of individual ports can be disabled by setting the
+ corresponding bits in the mask to 1. Bit 0 is for
+ the first port in the list above (0x1f0), and so on.
+ By default all supported ports are probed.
+
+ pata_legacy.qdi= [HW,LIBATA]
+ Format: <int>
+ Set to non-zero to probe QDI controllers. By default
+ set to 1 if CONFIG_PATA_QDI_MODULE, 0 otherwise.
+
+ pata_legacy.winbond= [HW,LIBATA]
+ Format: <int>
+ Set to non-zero to probe Winbond controllers. Use
+ the standard I/O port (0x130) if 1, otherwise the
+ value given is the I/O port to use (typically 0x1b0).
+ By default set to 1 if CONFIG_PATA_WINBOND_VLB_MODULE,
+ 0 otherwise.
+
+ pata_platform.pio_mask= [HW,LIBATA]
+ Format: <int>
+ Supported PIO mode mask. Set individual bits to allow
+ the use of the respective PIO modes. Bit 0 is for
+ mode 0, bit 1 is for mode 1, and so on. Mode 0 only
+ allowed by default.
+
pause_on_oops=
Halt all CPUs after the first oops has been printed for
the specified number of seconds. This is to be used if
