[PATCH] pcmcia: yenta override to re-allocate resources
From: Manfred Spraul
One bios assigns a small window for i/o access to yenta bridges. But there
are Cardbus cards that needs lots of i/o ports. yenta usually honors the bios
selected values, except if the bios choice is clearly invalid. The patch
allows an override from the command line.
