Hmm, I think I was a bit confused there. So (a) you're right that
the non-SMP case doesn't have a platform dependency so it will
work on anything that wants to call arm_load_kernel (including
omap boards). (b) omap1-3 are all single core anyhow, and I don't
know of anybody who's proposing to write an omap4 model right now
(c) the currently-out-of-tree omap3 models don't call arm_load_kernel
but instead have a model of the omap3 boot rom and just boot from
SD card images like the real hardware. [It's (c) that I was vaguely
thinking of when I wrote that remark.]
