Achin Gupta 994dfceb44 psci: fix values of incorrectly defined constants
This patch fixes the following constant values in the psci.h:

1. The affinity level shift value in the power_state parameter of the
   cpu_suspend psci call. The previous value was preventing shutdown
   of the affinity level 1.

2. The values used for affinity state constants (ON, OFF,
   ON_PENDING). They did not match the values expected to be returned
   by the affinity_info psci api as mentioned in the spec.

3. The state id shift value in the power_state parameter of the
   cpu_suspend psci call.

Achin Gupta 4a826ddad8 rework general purpose registers save and restore
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.

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 295538bc37 AArch64: Remove EL-agnostic TLB helper functions
Also, don't invalidate the TLBs in disable_mmu() function, it's better
to do it in enable_mmu() function just before actually enabling the
MMU.

Sandrine Bailleux 3738274dc1 Unmask SError and Debug exceptions.
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.
