OK, fine. I'll add it to omap-for-linus and merge it. No need to
wait a week on this.

With the recent changes all known mach-omap2 boards should
be now bootable with just:

$ rm .config
$ echo CONFIG_ARCH_OMAP=y > .config
$ yes "" | ARCH=arm make oldconfig

Of course the drivers still need to be selected and CMDLINE needs
to be set for some boards not suporting bootloader cmdline options.
And CONFIG_SMP can't be selected on uncore boards.

Cheers,
