From: Sekhar Nori <nsekhar@ti.com>

'flags' member of omap_hwmod structure is fast running
out of space with 16 different flags already defined.

Make flags a 32-bit entity so as to allow for more flags.

This results is a ~2.3K data section size increase with
TI config fragments.

This line needs to be changed to refer to omap2plus_defconfig.

I guess this data is probably stale as well. Here is the before and
after numbers using omap2plus_defconfig on v4.11-rc2

before:
   text	   data	    bss	    dec	    hex	filename
8186930	3082444	8252992	19522366	129e33e	vmlinux

after:
   text	   data	    bss	    dec	    hex	filename
8186922	3084812	8252992	19524726	129ec76	vmlinux

The size increase remains at ~2.3K in data section.

Thanks,
Sekhar

Thanks for the new figures. I'll resend the patch with updated data.
