The BL3-1 firmware code is stored in TZSRAM on Tegra186 platforms. This memory loses power when we enter System Suspend and so its contents are stored to TZDRAM, before entry. This opens up an attack vector where the TZDRAM contents might be tampered with when we are in the System Suspend mode. To mitigate this attack the SE engine calculates the hash of entire TZSRAM and stores it in PMC scratch, before we copy data to TZDRAM. The WB0 code will validate the TZDRAM and match the hash with the one in PMC scratch. This patch adds driver for the SE engine, with APIs to calculate the hash and store SE SHA256 hash-result to PMC scratch registers.
