commit 0e7d59ed7b6a456009f174bd5f98d4b8f31d8518 Author: Duncan Laurie dlaurie@chromium.org Date: Mon Aug 27 13:51:23 2012 -0700
ELOG: Don't disable SPI controller lockdown
Now that WREN prefix is handled properly ELOG is able to write when the SPI controller is locked down.
To test, ensure that runtime SPI write via ELOG is successful by checking the event log for a kernel shutdown reason code:
5 | 2012-08-27 11:09:48 | Kernel Event | Clean Shutdown 6 | 2012-08-27 11:09:50 | System boot | 26 7 | 2012-08-27 11:09:50 | System Reset
