PATCH 1/1 QEMU: IDE support for mips

Hi,

The attached patch adds IDE support on the mips target. It has been written by Daniel Jacobowitz, and posted on [email protected], along with another patch. He told me it is ok to submit it.

I am using it for a week, it works correctly. Could you apply it?

Thanks,
Aurelien
