Tegra recently moved to the new I2C framework, which sets up I2C prior to
relocation, and prior to calling i2c_init_board(). This causes a crash on
Tegra boards.
note:
There are many ways to fix this. I believe this is one. It disables i2c_init()
until relocation is complete. I have been unable to test it so far due to
problems getting my Seaboard to work. I will try another Tegra board, but
send this for comment in the meantime.
