Ahh, we already had this flame war^W^Wdiscussion on port-sparc64. ;-)
With the way macppc does it every port needs its own attachment
glue through a MD i2c bus. Thus duplicating this attachment glue
code over and over again for every port.
This is simply not true.
But how else would you do it?
Did you look at the attachment? None of it is in any way macppc
specific. All it does is to pass a name, an i2c_tag_t and a bus
address. Nothing MD in there. ( the node member isn't in use anyway
and should have been deleted long ago )
If we wanted to suport direct configuration of i2c devices on
sparc64 like on macppc, we would need
to add a, say, si2c bus to sparc64. Just like ki2c on macppc.
Again, that's nonsense. You can recycle the exact same attachment on
either one of them.
Thus resulting in a specialized, sparc64 MD si2c bus attachment.
I have no idea how you got to that conclusion.
