      Allow BL3-2 platform definitions to be optional · 1151c821
      Dan Handley authored
      The generic image loading and IO FIP code no longer forces the
      platform to create BL3-2 (Secure-EL1 Payload) specific
      definitions. The BL3-2 loading code in bl2/bl2main.c is wrapped
      by a #ifdef BL32_BASE blocks, allowing the BL3-2 definitions to
      be optional. Similarly for the name_uuid array defintion in
      drivers/io/io_fip.c.
      
      Also update the porting guide to reflect this change.
      
      The BL3-2 platform definitions remain non-configurably present
      in the FVP port.

      Remove variables from .data section · 625de1d4
      Dan Handley authored
      Update code base to remove variables from the .data section,
      mainly by using const static data where possible and adding
      the const specifier as required. Most changes are to the IO
      subsystem, including the framework APIs. The FVP power
      management code is also affected.
      
      Delay initialization of the global static variable,
      next_image_type in bl31_main.c, until it is realy needed.
      Doing this moves the variable from the .data to the .bss
      section.
      
      Also review the IO interface for inconsistencies, using
      uintptr_t where possible instead of void *. Remove the
      io_handle and io_dev_handle typedefs, which were
      unnecessary, replacing instances with uintptr_t.
      
      Fixes ARM-software/tf-issues#107.

      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.

      Move include and source files to logical locations · 4ecca339
      Dan Handley authored
      Move almost all system include files to a logical sub-directory
      under ./include. The only remaining system include directories
      not under ./include are specific to the platform. Move the
      corresponding source files to match the include directory
      structure.
      
      Also remove pm.h as it is no longer used.

      Fix file_to_uuid() function · 493c8cb2
      Sandrine Bailleux authored
      This patch fixes a bug in the 'file_to_uuid()' function: it used
      to cause an exception by dereferencing a null pointer when
      a given UUID was not found in the UUID array. The fix is to delete
      the final null entry in the UUID array, which is not needed because
      the array is statically declared so its size is known at build time.
      
      Fixes ARM-software/tf-issues#43

      Add Firmware Image Package (FIP) driver · 561cd33e
      Harry Liebel authored
      The Firmware Image Package (FIP) driver allows for data to be loaded
      from a FIP on platform storage. The FVP supports loading bootloader
      images from a FIP located in NOR FLASH.
      
      The implemented FVP policy states that bootloader images will be
      loaded from a FIP in NOR FLASH if available and fall back to loading
      individual images from semi-hosting.
      
      NOTE:
      - BL3-3(e.g. UEFI) is loaded into DRAM and needs to be configured
        to run from the BL33_BASE address. This is currently set to
        DRAM_BASE+128MB for the FVP.

      Implement load_image in terms of IO abstraction · 9d72b4ea
      James Morrissey authored
      The modified implementation uses the IO abstraction rather than
      making direct semi-hosting calls.  The semi-hosting driver is now
      registered for the FVP platform during initialisation of each boot
      stage where it is used.  Additionally, the FVP platform includes a
      straightforward implementation of 'plat_get_image_source' which
      provides a generic means for the 'load_image' function to determine
      how to access the image data.

      Add IO abstraction framework · f2f9bb5e
      James Morrissey authored
      This is intended primarily for use as a storage abstraction.
      It allows operations such as image-loading to be implemented
      in a platform-independent fashion.  Each platform registers
      a set of IO drivers during initialisation.  The platform must
      also provide a function that will return a device and a specifier
      that can be used to access specified content.
      
      Clients of the API will primarily use device and entity handles.
      The term "entity" is deliberately vague, to allow for different
      representations of content accessed using different types of
      specifier, but will often be interpreted as a "file" where the
      specifier will normally be its path.
      
      This commit builds, but is intended to be paired with a sample
      implementation of "load_image" using a semi-hosting driver on FVP.
