Sandrine Bailleux 65f546a14f Properly initialise the C runtime environment
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.

Sandrine Bailleux 8d69a03f6a Various improvements/cleanups on the linker scripts
- 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.

Sandrine Bailleux 204aa03da7 fvp: Remove unnecessary initializers
Global and static variables are expected to be initialised to zero
by default.  This is specified by the C99 standard. This patch
removes some unnecessary initialisations of such variables.

It fixes a compilation warning at the same time:
  plat/fvp/bl31_plat_setup.c:82:3: warning: missing braces around
  initializer [-Wmissing-braces]
     section("tzfw_coherent_mem"))) = {0};
     ^
  plat/fvp/bl31_plat_setup.c:82:3: warning: (near initialization for
  ‘ns_entry_info[0]’) [-Wmissing-braces]

Note that GCC should not have emitted this warning message in the
first place.  The C Standard permits braces to be elided around
subaggregate initializers.  See this GCC bug report:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119

- The Foundation FVP only has one cluster and does not have
  CCI.
