The Acer Chromebook 13, codenamed "Big", contains an NVIDIA tegra124
processor and is similar to the Venice2 reference platform.

The keyboard, USB 2, audio, HDMI, sdcard and emmc have been tested
and work on the 1366x768 models.  I haven't tried on the HD systems
yet.

WiFi does not yet work, it needs at least some PMIC changes to enable
the 32k clock.

The elan trackpad is not yet functional but hopefully will be soon as
there are patches under review.

There is also an issue on reboot because the TPM isn't reset.  It will
cause the stock firmware to enter recovery mode.  This can be worked
around by an EC-reset, press refresh and power at the same time.
Hi Dylan,

do you have any more information regarding this problem that could
save me some investigation?
The PMC reset does not reset the TPM, so the reset pin (GPIO I5) must
be toggled instead.
