Things must be setup to a certain extent or we couldn't have been loaded
by ROM, yes. Since am35x parts are a different family from the omap3
boards, I'll double check what the am3517 evm I have says here as well.
For correctness however, we currently are turning on the i2c support
in SPL and then not using it. So something should be changed :)
