From 908ceefd25ffd6427c3a53502598006bacf22750 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Wed, 17 Dec 2014 17:38:38 -0800 Subject: veyron: Fix TPM I2C initialization and sync boards Due to a missing i2c_init(), we were actually running our TPM with default divisors at 660KHz. Oops. While it's commendable that both the TPM and our controller seem to have been running fine all this time at more than 1.5 times the maximum frequency they support, we should probably still get that fixed. Also sync Speedy back up to the other Veyron boards since it seems to have missed a recent SDMMC patch. BRANCH=None BUG=None TEST=Booted Pinky.
