As omap1 and omap2 will never be compiled together, due to
different compiler flags, so we can simply make
cpu_class_is_omap2() = true, for all non-omap1 platforms.

Tony,

Ping???
Thanks applying into devel-am33xx branch.
Actually looks like this fails for the dynamic detection
case with omap1_defconfig.. Looks like you did not build
test your patch with omap1_defconfig? Please do it for
every patch!

It seems we need something better though for multi zImage
too, we can't really rely on CONFIG_ARCH_OMAP1 or
CONFIG_ARCH_OMAP2PLUS here to determine anything.

Anyways, dropping this for now, let's try to come up
with something better.
Yes Tony, you are right I did not test omap1 for this patch. My bad...

How about something like, considering the fact that, omap_type() is the 
culprit here and is not applicable to omap1 at all. In case of omap1, we 
don't use omap_type() function.
