Yeah I've been thinking about that too earlier. We could have common
devices.c with the init code, then dev24xx.c and dev34xx.c et al
would just call the common init functions with something like this:


static int __init dev34xx_init(void)
{
	if (!cpu_is_omap34xx())
		return -ENODEV;

	omap_init_mbox(omap34xx_mbox_resources, omap34xx_mbox_nr_resources);
	omap_init_sti(omap34xx_sti_resources, omap34xx_sti_nr_resources);
	...	

	return 0;
}

subsys_initcall(emu_init);

Of course that needs to be coordinated with the pending hwmod patches.

I think we can achieve most of that by right naming of the files and
with hwmod. Having separate directories typically means multiple copies
of almost the same code.
