Hi Tom,
[snip]
But, crap, breaks am335x_evm (and probably beaglebones, etc). I'll dig into this more to see if I can spot something obvious tomorrow.
Made it work on the am335x_evm (tested, with AM3359 on board). Problem was in the new i2c_probe, which on this board is called by the SPL and caused a hang (interestingly, when called from regular u-boot, works fine). Fix is to add a small delay. Clocking and I2C speed should be identical between SPL and U-Boot, but probably are not; I did not have time to look with a scope, but don't have any other reasonable explanation. Whatever, now it is working. I shall submit the patch tonight.

Just tested on Beaglebone, works fine as well.
