Secure Monitor

Secure Monitor was updated.

• CPU Suspend SMC code now explicitly initializes the state of I2C5 before communicating with the PMIC, instead of assuming that it is in a valid state.
• Code for initializing MMIO inside package2ldr now writes random values to a number of PMC secure scratch registers, and validates that the written values are read back successfully before locking the scratch.
  • TODO: Check back later for information on what these scratch do.

KernelLdr

KernelLdr was updated.

• TPIDR_EL1 is now set to 0, and VBAR_EL1 is now set to a table that infinite loops on all exceptions other than synchronous from same exception level.
  • synch_spx_el1 now restores a number of registers from a context with pointer in TPIDR_EL1.
• TPIDR_EL1 is now set to a context save struct before manufacturer-specific system registers are set, and validated to be non-0/NULL afterwards. It is then cleared.
  • Support was added for Cortex-A53 specific CPU initialization.
• Kernel .rodata is now initially mapped as RW- instead of R--, and then reprotected to R-- after relocations are completed.
  • This allows for/implements .rel.ro.
