      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'

      Do not trap access to floating point registers · 4f603683
      Harry Liebel authored
      Traps when accessing architectural features are disabled by clearing bits
      in CPTR_EL3 during early boot, including accesses to floating point
      registers. The value of this register was previously undetermined, causing
      unwanted traps to EL3. Future EL3 code (for example, context save/restore
      code) may use floating point registers, although they are not used by current
      code.
      
      Also, the '-mgeneral-regs-only' flag is enabled in the GCC settings to
      prevent generation of code that uses floating point registers.

      rework general purpose registers save and restore · 4a826dda
      Achin Gupta authored
      The runtime exception handling assembler code used magic numbers for
      saving and restoring the general purpose register context on stack
      memory. The memory is interpreted as a 'gp_regs' structure and the
      magic numbers are offsets to members of this structure. This patch
      replaces the magic number offsets with constants. It also adds compile
      time assertions to prevent an incorrect assembler view of this
      structure.

      Properly initialise the C runtime environment · 65f546a1
      Sandrine Bailleux authored
      This patch makes sure the C runtime environment is properly
      initialised before executing any C code.
      
        - Zero-initialise NOBITS sections (e.g. the bss section).
        - Relocate BL1 data from ROM to RAM.

      Various improvements/cleanups on the linker scripts · 8d69a03f
      Sandrine Bailleux authored
        - Check at link-time that bootloader images will fit in memory
          at run time and that they won't overlap each other.
        - Remove text and rodata orphan sections.
        - Define new linker symbols to remove the need for platform setup
          code to know the order of sections.
        - Reduce the size of the raw binary images by cutting some sections
          out of the disk image and allocating them at load time, whenever
          possible.
        - Rework alignment constraints on sections.
        - Remove unused linker symbols.
        - Homogenize linker symbols names across all BLs.
        - Add some comments in the linker scripts.

      Unmask SError and Debug exceptions. · 3738274d
      Sandrine Bailleux authored
      Any asynchronous exception caused by the firmware should be handled
      in the firmware itself.  For this reason, unmask SError exceptions
      (and Debug ones as well) on all boot paths.  Also route external
      abort and SError interrupts to EL3, otherwise they will target EL1.

      Move generic architectural setup out of blx_plat_arch_setup(). · c10bd2ce
      Sandrine Bailleux authored
      blx_plat_arch_setup() should only perform platform-specific
      architectural setup, e.g. enabling the MMU.  This patch moves
      generic architectural setup code out of blx_plat_arch_setup().
