Subject: [PATCH] smc911x irq sense request and MPR2 board support

Hi,

this are the changes to the smc911x driver, which were necessary
to get it running on the Magic Panel R2 (smsc9115).
It is a SH3-DSP based board. The other patches are available on 
the linuxsh-dev mailinglist.
http://marc.info/?l=linuxsh-dev&r=1&b=200708&w=2

It was necessary to set the irq sense to low level.
Therefor the SMC_IRQ_SENSE define was added.
How are the chances for inclusion in 2.6.24?
