Use your old config file, or just unselect CONFIG_ARCH_OMAP2
and CONFIG_ARCH_OMAP3. Note that if you now do:

$ yes "" | ARCH=arm make oldconfig

with your old omap4 only config file, then by default the
typical features get added by default. So what you probably
want to do is (untested):

$ echo "# CONFIG_ARCH_OMAP2PLUS_TYPICAL is not set" >> .config
$ yes "" | ARCH=arm make oldconfig

Then it should not change your old config file.

To see how the boards and features show up, you can also play
with it with make xconfig:

System Type -> TI OMAP2/3/4 Specific Features

Uncheck TI OMAP2 and TI OMAP3 so only TI OMAP4 is selected.
