2014-03-14ARM: tegra: remove CONFIG_USE_SECURE_KERNEL usageVarun Wadekar
Remove the config variable usage from the kernel and make the secure firmware check dynamic. This make LP1 resume tricky since we need to execute out of TZRAM till SDRAM is out of self-refresh. To fix this, store secure firmware presence bit in TZRAM during boot.
