      Introduce macros to manipulate the SPSR · 23ff9baa
      Vikram Kanigiri authored
      This patch introduces macros (SPSR_64 and SPSR_32) to
      create a SPSR for both aarch32 and aarch64 execution
      states. These macros allow the user to set fields
      in the SPSR depending upon its format.
      The make_spsr() function which did not allow
      manipulation of all the fields in the aarch32 SPSR
      has been replaced by these new macros.

      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.
      
      Fixes ARM-software/tf-issues#31

      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.

      Separate BL functions out of arch.h · 5b827a8f
      Dan Handley authored
      Move the BL function prototypes out of arch.h and into the
      appropriate header files to allow more efficient header file
      inclusion. Create new BL private header files where there is no
      sensible existing header file.

      Remove partially qualified asm helper functions · 6ba0b6d6
      Vikram Kanigiri authored
      Each ARM Trusted Firmware image should know in which EL it is running
      and it should use the corresponding register directly instead of reading
      currentEL and knowing which asm register to read/write

      Rework BL2 to BL3-1 hand over interface · e4d084ea
      Achin Gupta authored
      This patch reworks BL2 to BL3-1 hand over interface by introducing a
      composite structure (bl31_args) that holds the superset of information
      that needs to be passed from BL2 to BL3-1.
      
        - The extents of secure memory available to BL3-1
        - The extents of memory available to BL3-2 (not yet implemented) and
          BL3-3
        - Information to execute BL3-2 (not yet implemented) and BL3-3 images
      
      This patch also introduces a new platform API (bl2_get_bl31_args_ptr)
      that needs to be implemented by the platform code to export reference to
      bl31_args structure which has been allocated in platform-defined memory.
      
      The platform will initialize the extents of memory available to BL3-3
      during early platform setup in bl31_args structure. This obviates the
      need for bl2_get_ns_mem_layout platform API.
      
      BL2 calls the bl2_get_bl31_args_ptr function to get a reference to
      bl31_args structure. It uses the 'bl33_meminfo' field of this structure
      to load the BL3-3 image. It sets the entry point information for the
      BL3-3 image in the 'bl33_image_info' field of this structure. The
      reference to this structure is passed to the BL3-1 image.
      
      Also fixes issue ARM-software/tf-issues#25

      Remove useless copies of meminfo structures · ee12f6f7
      Sandrine Bailleux authored
      Platform setup code has to reserve some memory for storing the
      memory layout information.  It is populated in early platform setup
      code.
      
      blx_get_sec_mem_layout() functions used to return a copy of this
      structure.  This patch modifies blx_get_sec_mem_layout() functions
      so that they now directly return a pointer to their memory layout
      structure.  It ensures that the memory layout returned by
      blx_get_sec_mem_layout() is always up-to-date and also avoids a
      useless copy of the meminfo structure.
      
      Also rename blx_get_sec_mem_layout() to blx_plat_sec_mem_layout()
      to make it clear those functions are platform specific.
