Unless I'm missing something, you should enable the SCU before starting
secondary CPUs.  It's also a good idea to structure the code with
separate prepare and boot functions even if all the current chips are
only dual-core.

About the SCU: I will check with the firmware author.
About prepare: this is the firmware's responsibility.
(Not all chips are dual-core, the 8756 is single-core.)

Then the DT should say so.

Rule 0: never trust the firmware.

What about other registers?  Does the firmware support setting the
prefetch control register?

Yes, after masking out some bits.

Then you should provide the kernel with a means of doing that.  Is the
SMC ID from OMAP4 correct?
