From 751a57f1e20223d403ec77ab33e797d486e7d256 Mon Sep 17 00:00:00 2001 From: Riley Andrews Date: Thu, 5 May 2016 14:42:41 -0700 Subject: trusty: Add trusty logging driver. This driver is the consumer side of a ringbuffer of log data that the secure operating system dumps prints into. Trusty printfs will be dumped into the kernel log after smc calls and during panics.
