      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

      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.
