      tzc: Fix MISRA defects · af6491f8
      Antonio Nino Diaz authored
      
      
      The definitions FAIL_CONTROL_*_SHIFT were incorrect, they have been
      fixed.
      
      The types tzc_region_attributes_t and tzc_action_t have been removed and
      replaced by unsigned int because it is not allowed to do logical
      operations on enums.
      
      Also, fix some address definitions in arm_def.h.

      TZC: rename included C file to a header · 239b085c
      Antonio Nino Diaz authored
      
      
      C files shouldn't be included into others. This file only contains some
      macros and functions that can be made `static inline`, so it is ok to
      convert it into a header file.
      
      This is the only occurrence of a C file being included in another one in
      the codebase instead of using a header, other occurrences are a way of
      achieving backwards-compatibility.
      
      Functions therein have been qualified as `inline`.

      AArch32: Enable GIC and TZC support · 367d0ffb
      Soby Mathew authored
      This patch modifies GICv3 and TZC drivers to add AArch32 support.
      No modifications are required for the GICv2 driver for AArch32 support.
      The TZC driver assumes that the secure world is running in Little-Endian
      mode to do 64 bit manipulations. Assertions are present to validate the
      assumption.
      
      Note: The legacy GICv3 driver is not supported for AArch32.

      Use unsigned long long instead of uintptr_t in TZC400/DMC500 drivers · 9fbdb802
      Yatharth Kochar authored
      Currently the `tzc400_configure_region` and `tzc_dmc500_configure_region`
      functions uses uintptr_t as the data type for `region_top` and `region_base`
      variables, which will be converted to 32/64 bits for AArch32/AArch64
      respectively. But the expectation is to keep these addresses at least 64 bit.
      
      This patch modifies the data types to make it at least 64 bit by using
      unsigned long long instead of uintptr_t for the `region_top` and
      `region_base` variables. It also modifies the associated macros
      `_tzc##fn_name##_write_region_xxx` accordingly.

      Refactor the ARM CoreLink TZC-400 driver · 6b477063
      Vikram Kanigiri authored
      TrustZone protection can be programmed by both memory and TrustZone
      address space controllers like DMC-500 and TZC-400. These peripherals
      share a similar programmer's view.
      
      Furthermore, it is possible to have multiple instances of each type of
      peripheral in a system resulting in multiple programmer's views.
      For example, on the TZC-400 each of the 4 filter units can be enabled
      or disabled for each region. There is a single set of registers to
      program the region attributes. On the DMC-500, each filter unit has its
      own programmer's view resulting in multiple sets of registers to program
      the region attributes. The layout of the registers is almost the same
      across all these variations.
      
      Hence the existing driver in `tzc400\tzc400.c` is refactored into the
      new driver in `tzc\tzc400.c`. The previous driver file is still maintained
      for compatibility and it is now deprecated.
