>Description:
Revision 1.5 of src/sys/arch/arm/xscale/i80321_pci.c causes the iyonix port to hang after the following:

From a while ago:

NetBSD 2.99.11 (iyonix-GENERIC) #10: Sun Dec 12 19:41:34 GMT 2004
        root@iris.absd.org:/tmp/iyonix-GENERIC

i80321: BANK0 = 0x10000000 BANK1 = 0x10000000

And again, with today's -current:

NetBSD 2.99.16 (iyonix-GENERIC) #1: Tue Feb 22 22:46:01 GMT 2005
        abs@iris.absd.org:/home/gavan/current/obj/iyonix-GENERIC

avail memory = 121 MB

i80321: BANK0 = 0x08000000 BANK1 = 0x00000000

>How-To-Repeat:
Attempt to boot a recent NetBSD/iyonix kernel.
>Fix:
The simple fix, for NetBSD/iyonix, is to revert the change between revisions 1.4 and 1.5 of i80321_pci.c. This obviously doesn't address the reason for making the change in the first place, though.
