OK, here is a revised patch which uses pci= option instead of config
parameters.

Sorry, this patch would cause build failure if setup-bus.c was not
built into kernel. Revised again.


Subject: [PATCH] Make CARDBUS_MEM_SIZE and CARDBUS_IO_SIZE customizable

CARDBUS_MEM_SIZE was increased to 64MB on 2.6.20-rc2, but larger size
might result in allocation failure for the reserving itself on some
platforms (for example typical 32bit MIPS). Make it (and
CARDBUS_IO_SIZE too) customizable by "pci=" option for such platforms.

Hi, I've got the feeling that those two parameters don't do the same things, although they have the same description ;-) Maybe the texts could be:
* The fixed amount of bus space which is reserved for the CardBus bridges IO window.
* The fixed amount of bus space which is reserved for the CardBus bridges memory window.

See you,
Eric
