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.
