From: Chris Morgan <macromorgan@xxxxxxxxxxx> Add the '-@' DTC option for the Rock 5B and Indiedroid Nova devices. These two devices are relatively new both with external GPIO headers for expansion. This does impact the filesize of the DTB substantially.
I think that enabling this should be either left to Linux distributions, to be enabled for all the dtbs they ship, which they already do, or be enabled by us for all Rockchip DTs, instead of for enabling it just for some boards. However, I think that leaving it to Linux distributions is the preferred way.
