      Tegra194: save system suspend entry marker to TZDRAM · 040529e9
      Varun Wadekar authored 
      

This patch adds support to save the system suspend entry and exit
markers to TZDRAM to help the trampoline code decide if the current
warmboot is actually an exit from System Suspend.

The Tegra194 platform handler sets the system suspend entry marker
before entering SC7 state and the trampoline flips the state back to
system resume, on exiting SC7.

      Tegra194: helper functions for CPU rst handler and SMMU ctx offset · 653fc380
      Varun Wadekar authored 
      

This patch adds a helper function to get the SMMU context's offset
and uses another helper function to get the CPU trampoline offset.
These helper functions are used by the System Suspend entry sequence
to save the SMMU context and CPU reset handler to TZDRAM.
