This patch introduces SiP function ID, 0xC200FF00, to read SMMU_PER error records from all supported SMMU blocks. The register values are passed over to the client via CPU registers X1 - X3, where X1 = SMMU_PER[instance #1] | SMMU_PER[instance #0] X2 = SMMU_PER[instance #3] | SMMU_PER[instance #2] X3 = SMMU_PER[instance #5] | SMMU_PER[instance #4] Change-Id: Id56263f558838ad05f6021f8432e618e99e190fc Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

The 'plat_core_pos_by_mpidr' handler gets called very early during boot and the compiler generated code overwrites the caller's registers. This patch converts the 'plat_core_pos_by_mpidr' handler into an assembly function and uses registers x0-x3, to fix this anomaly.

We set deepest power state when offlining a core but that may not be requested by non-secure sw which controls idle states. It will re-init this info from non-secure software when the core come online. This patch resets the power state in the non-secure world context to allow it to start with a clean slate.

TZSRAM loses power during System suspend, so the entire contents are copied to TZDRAM before Sysem Suspend entry. The warmboot code verifies and restores the contents to TZSRAM during System Resume. This patch removes the code that sets up CPU vector to point to TZSRAM during System Resume as a result. The trampoline code can also be completely removed as a result.

This patch disables the code to program reset vector for secondary CPUs to a different entry point, than cold boot. The cold boot entry point has the ability to differentiate between a cold boot and a warm boot, that is controlled by the PROGRAMMABLE_RESET_ADDRESS macro. By reusing the same entry point, we can lock the CPU reset vector during cold boot. Change-Id: Iad400841d57c139469e1d29b5d467197e11958c4 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

SMMU and MC registers are saved as part of the System Suspend sequence. The register list includes some NS world SMMU registers that need to be saved by NS world software instead. All that remains as a result are the MC registers. This patch moves code to MC file as a result and renames all the variables and defines to use the MC prefix instead of SMMU. The Tegra186 and Tegra194 platform ports are updated to provide the MC context register list to the parent driver. The memory required for context save is reduced due to removal of the SMMU registers. Change-Id: I83a05079039f52f9ce91c938ada6cd6dfd9c843f Signed-off-by: Pritesh Raithatha <praithatha@nvidia.com>

The platform code already contains the initial set of MC SID security configs to be locked during boot. This patch adds some more configs to the list. Since the reset value of these registers is already as per expectations, there is no need to change it. MC SID security configs - PTCR, - MIU6R, MIU6W, MIU7R, MIU7W, - MPCORER, MPCOREW, - NVDEC1SRD, NVDEC1SRD1, NVDEC1SWR.

The BL3-1 firmware code is stored in TZSRAM on Tegra194 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 to PMC scratch registers.

As bpmp-fw is running at the same time as ATF, and the mss client reconfiguration sequence involves performing a hot flush resets on bpmp, there is a chance that bpmp-fw is trying to perform accesses while the hot flush is active. Therefore, the mss client reconfigure has been moved to System Suspend resume fw and bootloader, and it can be removed from here.

Commit ac71344e moved the base address for the MMIO aperture of the console inside the console_t struct. As a result, the driver should now save the MMIO base address to console_t at offset marked by the CONSOLE_T_BASE macro. This patch updates the SPE console driver to use the CONSOLE_T_BASE macro to save/access the MMIO base address.
