Hello,

PCMCIA is broken on my Au1200 platform. Seems to me that accesses to Attribute
memory are broken; a dump of the CIS reveals the following:

it should look like this:

Reverting "[PATCH] Generic ioremap_page_range: mips conversion" makes it
work again:
http://www.linux-mips.org/git?p=linux.git;a=commitdiff_plain;h=8e087929df884dbb13e383d49d192bdd6928ecbf;hp=62dfb5541a025b47df9405ff0219c7829a97d83b

The socket driver I use is a simplified version of au1000_generic and
au1000_db1x00 combined. None of those have received any updates since
the above mentioned patch went it.

Thanks!
