Okay, after some more testing, I'd like to remove the !OF for next iteration.
The reason is that I have a usecase where I have a single kernel image with
devictree support (ie CONFIG_OF=y), but with support for both devicetree and
legacy platforms. In this case, a platform such as lubbock can boot :
 - with devicetree
 - with legacy arch/arm/mach-pxa/lubbock.c

In this kernel, the !OF Kconfig prevents the legacy version from working, as
pxa2xx-cpufreq is descarded even if it is needed in the legacy version.

Therefore, I'd like to respin without this !OF.

Cheers.
