Hi,
this patch adds the mac-io IDE support to openBIOS. It works well with openBIOS (to load kernel) and with kernel 2.4 but has some problems with linux 2.6.
For instance, using debian-31r8-powerpc-netinst.iso with kernel 2.4 works well (but not kernel 2.6), but using debian-40r6-powerpc- netinst.iso fails when debian-installer loads all udeb components.
Is there a bug in qemu, linux or the mac-io IDE device tree is not initialized correctly ?
I have tried your patch on already installed disk image, and it works without problem. I tried Debian etch (kernel 2.6.18), etchnhalf (kernel 2.6.24) and lenny (kernel 2.6.26).
I haven't done any change on the qemu side. Given that the mac-io ide is detected before the CMD646, I have to pass -hdc to the disk image so that it is recognized as -hda by Linux. I'll do test with the different install CD tomorrow.
