168fcf58c5 arm946e: add icache/dcache manipulation commands.
Provide cache operations coherent with internal target state.
Functions similar to xscale target.

f1e9cef410 arm946e: cp15 command returns value to the script
Not just print it.

This enables scripts to analyze valuable config options of
arm946e-s cores, do internal BIST memory tests and more.

Be careful to flush caches before disabling it.
Do not forget that BIST test overwrites  memory.

 - cp15 rewritten from COMMAND_HANDLER to jim_handler.

63687807cc arm946e: cleanup C0.C cache type reg access
Cache type register C0.C is read-only, and display
hard core configuration information.
This information is unlikely be changed in runtime.

 - removed C0.C access when result is not used in
   arm946e_invalidate_dcache()
 - access C0.C only once per target, store result
   in cp15_cache_info field of target structure
 - fix cache index count calculation

9c9c06b8ae arm946e: don't use global variables for context
Global variables 'dc' 'ic' had been used in the code
to keep target's state of D-cache and I-cache
on debug entry.

This may lead to incorrect operation in configurations
with multiple cores and unequal cache states.

Fix: move cache state to the appropriate bits of the
'cp15_control_reg' field (already present but unused).
Vaule of cp15 control register stored here on
arm946e_post_debug_entry(), and analyzed later
in arm946e_write_memory().

0535531d27 nit: more LOG_* \n fixes
Remove extra \n from LOG_DEBUG, LOG_INFO, and LOG_WARNING messages

Remove LOG_INFO_N
LOG_INFO_N was only used once and had a \n at the end

Change LOG_USER_N calls that end with \n to LOG_USER

9e3d43cfe7 arm964e: Add support for ARM946E target.
So far most of the people have been using existing ARM966E in the
place of ARM946E, because they have practically the same scan chains.

However, ARM946E has caches, which further complicates JATG handling
via scan-chain. this was preventing single-stepping for ARM946E when
SW breakpoints are used.

This patch thus introduces :
1) Correct cache handling on memory write
2) Possibility to flush whole cache and turn it off during debug, or
just to flush affected lines (faster and better)
3) Correct SW breakpoint handling and correct single-stepping
4) Corrects the bug on CP15 read and write, so CP15 values
are now correctly R/W
