Well, sometimes the philosophy of patches is to add something new
first and remove the old in a second separate patch if the system
can live with both. This makes it easier to digest single patches
(because they are smaller) and might also better pinpoint an issue
by bisect.

Ok, I see. Noted for RFCv2.

There will also be a big batch of changes for the compatible record
(omap3530->omap35xx, add omap34xx where needed) of ca. 10 board definition
DTS files. Should this then also become part of the new 2/5?

BR and thanks,
