      Juno: Implement initial platform port · 01b916bf
      Sandrine Bailleux authored
      This patch adds the initial port of the ARM Trusted Firmware on the Juno
      development platform. This port does not support a BL3-2 image or any PSCI APIs
      apart from PSCI_VERSION and PSCI_CPU_ON. It enables workarounds for selected
      Cortex-A57 (#806969 & #813420) errata and implements the workaround for a Juno
      platform errata (Defect id 831273).

      Add support for PSCI SYSTEM_OFF and SYSTEM_RESET APIs · d5f13093
      Juan Castillo authored
      This patch adds support for SYSTEM_OFF and SYSTEM_RESET PSCI
      operations. A platform should export handlers to complete the
      requested operation. The FVP port exports fvp_system_off() and
      fvp_system_reset() as an example.
      
      If the SPD provides a power management hook for system off and
      system reset, then the SPD is notified about the corresponding
      operation so it can do some bookkeeping. The TSPD exports
      tspd_system_off() and tspd_system_reset() for that purpose.
      
      Versatile Express shutdown and reset methods have been removed
      from the FDT as new PSCI sys_poweroff and sys_reset services
      have been added. For those kernels that do not support yet these
      PSCI services (i.e. GICv3 kernel), the original dtsi files have
      been renamed to *-no_psci.dtsi.
      
      Fixes ARM-software/tf-issues#218

      Refactor fvp_config into common platform header · 6f3b195a
      Dan Handley authored
      Changed the fvp_config array in fvp_common.c into a struct and
      moved into a new optional common platform header,
      include/plat/common/plat_config.h. Removed the config definitions
      in fvp_def.h and updated all references to the platform config.
      
      This makes the interface to the platform config cleaner and uses
      a little less RAM.
      
      Fixes ARM-software/tf-issues#180

      Per-cpu data cache restructuring · 5e910074
      Andrew Thoelke authored
      This patch prepares the per-cpu pointer cache for wider use by:
      * renaming the structure to cpu_data and placing in new header
      * providing accessors for this CPU, or other CPUs
      * splitting the initialization of the TPIDR pointer from the
        initialization of the cpu_data content
      * moving the crash stack initialization to a crash stack function
      * setting the TPIDR pointer very early during boot

      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.

      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.

      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.

      Change comments in assembler files to help ctags · 3a4cae05
      Jeenu Viswambharan authored
      Ctags seem to have a problem with generating tags for assembler symbols
      when a comment immediately follows an assembly label.
      
      This patch inserts a single space character between the label
      definition and the following comments to help ctags.
      
      The patch is generated by the command:
      
        git ls-files -- \*.S | xargs sed -i 's/^\([^:]\+\):;/\1: ;/1'
