- Some versions of u-boot for this Chromebook check for tpm node
- in the device tree and fail badly (reboot) if it is not found.
- While not exactly correct, it is much easier to patch the mainline
- device tree to match u-boot expectations than to fix u-boot on
- this device.
- See https://code.google.com/p/chromium/issues/detail?id=220169
