Sorry, my mistake (I was thinking on my feet) since secondary_startup is
declared in a C file, right? How about:

	ldr	lr, =secondary_startup
	b	ll_set_cpu_coherent

Why?  Do we really want LR to be the _virtual_ address?  No we don't,
because secondary_startup expects to be called with the MMU off.

So I go back to my original comment.  What's wrong with:

	bl	ll_set_cpu_coherent
	b	secondary_startup

?

Nothing wrong, it works perfectly.
Whereas indeed the code proposed by Will didn't work very well.
I will take Russell's suggestion.

Thanks,
