      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.

      Fix TZC-400 peripheral detection · 609ebce4
      Vikram Kanigiri authored
      The TZC-400 driver implementation incorrectly uses the component
      ID registers to detect the TZC-400 peripheral. As all ARM
      peripherals share the same component ID, it doesn't allow to
      uniquely identify the TZC-400 peripheral. This patch fixes the
      TZC-400 driver by relying on the `part_number_0` and
      `part_number_1` fields in the `PID` registers instead.
      The `tzc_read_component_id` function has been replaced by
      `tzc_read_peripheral_id`, which reads the 'part_number' values
      and compares them with the TZC-400 peripheral ID.
      
      Also, it adds a debug assertion to detect when the TZC driver
      initialisation function is called multiple times.

      Use uintptr_t as base address type in ARM driver APIs · 02462972
      Juan Castillo authored
      This patch changes the type of the base address parameter in the
      ARM device driver APIs to uintptr_t (GIC, CCI, TZC400, PL011). The
      uintptr_t type allows coverage of the whole memory space and to
      perform arithmetic operations on the addresses. ARM platform code
      has also been updated to use uintptr_t as GIC base address in the
      configuration.

      Add TZC function to configure region 0 · 71a84445
      Dan Handley authored
      Region 0 is special in TZC-400. It is possible to set the access
      permissions for this but not the address range or filters to which
      the permissions apply. Add a function for setting the region 0
      access permissions.
      
      Also add some VERBOSE logging and allow assembly files to include
      the TZC header.

      Juno: Reserve some DDR-DRAM for secure use · 740134e6
      Juan Castillo authored
      This patch configures the TrustZone Controller in Juno to split
      the 2GB DDR-DRAM memory at 0x80000000 into Secure and Non-Secure
      regions:
      
      - Secure DDR-DRAM: top 16 MB, except for the last 2 MB which are
        used by the SCP for DDR retraining
      - Non-Secure DDR-DRAM: remaining DRAM starting at base address
      
      Build option PLAT_TSP_LOCATION selects the location of the secure
      payload (BL3-2):
      
      - 'tsram' : Trusted SRAM (default option)
      - 'dram'  : Secure region in the DDR-DRAM (set by the TrustZone
                  controller)
      
      The MMU memory map has been updated to give BL2 permission to load
      BL3-2 into the DDR-DRAM secure region.

      Simplify interface to TZC-400 driver · 3279f625
      Dan Handley authored
      The TZC-400 driver previously allowed the possibility of multiple
      controller instances to be present in the same executable. This
      was unnecessary since there will only ever be one instance.
      
      This change simplifies the tzc_init() function to only take the
      base address argument needed by implementation, conforming to the
      driver initialization model of other drivers. It also hides some
      of the implementation details that were previously exposed by the
      API.
      
      The FVP port has been updated accordingly.
      
      THIS CHANGE REQUIRES ALL PLATFORM PORTS THAT USE THE TZC-400
      DRIVER TO BE UPDATED

      Reduce deep nesting of header files · 97043ac9
      Dan Handley authored
      Reduce the number of header files included from other header
      files as much as possible without splitting the files. Use forward
      declarations where possible. This allows removal of some unnecessary
      "#ifndef __ASSEMBLY__" statements.
      
      Also, review the .c and .S files for which header files really need
      including and reorder the #include statements alphabetically.

      Always use named structs in header files · fb037bfb
      Dan Handley authored
      Add tag names to all unnamed structs in header files. This
      allows forward declaration of structs, which is necessary to
      reduce header file nesting (to be implemented in a subsequent
      commit).
      
      Also change the typedef names across the codebase to use the _t
      suffix to be more conformant with the Linux coding style. The
      coding style actually prefers us not to use typedefs at all but
      this is considered a step too far for Trusted Firmware.
      
      Also change the IO framework structs defintions to use typedef'd
      structs to be consistent with the rest of the codebase.

      with individual security settings.

      This driver does not currently support raising an interrupt on access
      violation.
