Please note "st,stih410" is already present in device tree. The problem is that it is missing the entry in the match table, and so the L2 cache and other cpus than 0 don't get initialized.

This patch adds support to STiH410 SoC.

Please note "st,stih410" is already present in device tree.
The problem is that it is missing the entry in the match table,
and so the L2 cache and other cpus than 0 don't get initialized.

A number of configurations spit out warnings similar to:

warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0)
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)

Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
  eventually get rid of CACHE_PL310, surround these errata options with an
  if CACHE_L2X0 conditional rather than repeating the dependency against
  each.

 - add suspend support for PJ4B CPUs

 - rework interrupt masking for undefined instruction handling, which
   allows us to enable interrupts earlier in the handling of these

 - support for big endian page tables

 - fix stacktrace support to exclude stacktrace functions from the
   trace, and add save_stack_trace_regs() implementation so that kprobes
   can record stack traces.

 - Add support for the Cortex-A17 CPU.

 - Remove last vestiges of ARM710 support.

 - Removal of ARM "meminfo" structure, finally converting us solely to
   memblock to handle the early memory initialisation.
