There's some issue with Write Protect detection on the Jetson TX1
|
|
|
509cc04 |
so just apply a quirk to disable the check for the time being.

The Jetson TX1 dev kit doesn't ship with a screen by default and if
|
|
|
509cc04 |
it's not there it appears to crash on boot so disable them both by
|
|
|
509cc04 |
default until we work out the problem.
