I suspect that most of this is for the added devicetree code, and some more for the common-clk layer. For the omap1_defconfig, there is some hope to get part of the overhead back eventually by replacing board files with dts descriptions that are not part of the zImage itself, but it's unlikely to ever get smaller than it was.

I suspect that most of this is for the added devicetree code, and some more for the common-clk layer. For the omap1_defconfig, there is some hope to get part of the overhead back eventually by replacing board files with dts descriptions that are not part of the zImage itself, but it's unlikely to ever get smaller than it was.
