Subject: [PATCH 2/3] firmware: qcom: scm: disable SDI on Google WiFi
|
||
|
|
|
||
|
|
Google WiFi seems to have SDI (Secure Debug Image) enabled by default which
|
||
|
|
prevents normal reboot from working causing the board to just hang after
|
||
|
|
reboot is called.
|
||
|
|
|
||
|
|
So lets disable SDI during SCM probe on Google WiFi boards in order to
|
||
|
|
avoid a state where WDT will kick in and then the board will just hang
|
||
|
|
in the debug mode.
