The benefits of a user settable CONFIG_IDE_MAX_HWIFS have become pretty
tiny and are no longer considered worth the trouble of an own option.
Simply always #define MAX_HWIFS to 10.

Alan Cox has noticed some time ago that hpt34x is broken
(http://lkml.org/lkml/2007/7/3/257):
"No the old driver doesn't even do that. It starts up. It spuriously
adjusts some non writable PCI BAR registers, prints a message about
resources being in use already then exits."

These host drivers indirectly depend on CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS=y
which is defined only on alpha, x86, ia64, m32r, mips and ppc32.
Moreover:
- on ia64 there is no ISA
- m32r is too new for VLB
- on ppc32 ISA is available only on PPC_CHRP (no default IDE ports)
and PPC_PREP (marked as BROKEN)
[ the common sense tells me that VLB was only used on x86 but there
are urban legends that one of these host drivers was needed on some
other arch - thus the extra care ]
