A few months ago I wrote another patch to move some more platforms away 
from macide but it has not been tested yet. That is not to say you should 
wait. However, my patch does have some changes that are missing from your 
patch series, relating to ide platform devices in arch/m68k/mac/config.c. 
I hope to be able to test this patch before the 5.13 merge window closes.
