Tegra: memctrl_v2: secure the on-chip TZSRAM memory · d48c0c45

Varun Wadekar authored Dec 30, 2015



This patch programs the Memory controller's control registers
to disable non-secure accesses to the TZRAM. In case these
registers are already programmed by the BL2/BL30, then the
driver just bails out.

Tegra: memctrl_v2: Memory Controller Driver (v2) · 412dd5c5

Varun Wadekar authored Sep 20, 2015



This patch adds driver for the Memory Controller (v2) in the newer
Tegra SoCs. The newer hardware uses ARM's SMMU hardware instead of
the proprietary block in the past.
