OMAP 3430SDP i2c boot crash

[Tomi Valkeinen <tomi.valkeinen@nokia.com>]

Hi,

I haven't been able to boot my OMAP 3430SDP board with mainstream kernel
for a while, with the omap_3430sdp_defconfig. Anyone else having
problems? I don't get anything on the console after "Uncompressing
Linux... done, booting the kernel.", and Trace32 shows the log below.

 Tomi
