6f929dbd93 target files shouldn't #include <target/...h>
Make these ".h" files adopt the same policy the ".c" files already
follow:  don't use <subsystem/...h> syntax for private interfaces.

If we ever get reviewed/supported "public" interfaces they should
come exclusively from some include/... directory; that'll be the
time to switch to <...> syntax for any subsystem's own interfaces.

377c5504b9 change #include "armv4_5_mmu.h" to <target/armv4_5_mmu.h>
Changes from the flat namespace to heirarchical one.  Instead of writing:

	#include "armv4_5_mmu.h"

the following form should be used.

	#include <target/armv4_5_mmu.h>

The exception is from .c files in the same directory.

66ee303456 remove target_type register_command callback
Uses chaining of command_registration structures to eliminate all
target_type register_callback routines.  Exports the command_handler
registration arrays for those target types that are used by others.

0181296f61 ARM9TDMI: remove now-needless "struct arm9tdmi"
And move the rest of the vector_catch stuff into the C file;
it's not part of the module interface.

6a0af06bd9 ARM: shrink offsets
Move various embedded target structs to the beginnings of
their containers ... pretty much the way C++ or Obj-C
would for single inheritance.

This shrinks code that accesses those embedded structs by
letting common offsets use smaller instructions.  Sample
before/after sizes (on amd64):

  17181	    312	      0	  17493	   4455	arm920t.o
  16810	    312	      0	  17122	   42e2	arm920t.o

Where the "after" is the smaller number, with this patch
over the ones leveraging that embedding knowledge.

db116b1ea3 target: provide container_of()
Provide a cleaner way to handle single inheritance of targets
in C, using the same model Linux does:  structs containing other
structs, un-nested via calls to a "container_of()" macro that
are packaged in typesafe inline functions.

Targets already use this containment idiom, but make it much
more complicated because they un-nest using embedded "void *"
pointers ... in chains of up to five per target, which is all
pure needless complication.  (Example: arm92x core, arm9tdmi,
arm7_9, armv4_5 ... on top of the base "target" class.)

Applying this scheme consistently simplifies things, and gets
rid of many error-prone untyped pointers.  It won't change any
part of the type model though -- it just simplifies things.
(And facilitates more cleanup later on.)

Rule of thumb:  where there's an X->arch_info void* pointer,
access to that pointer can and should be removed.  It may be
convenient to set up pointers to some of the embedded structs;
and shrink their current "*_common" names (annoyingly long).

aab023570b ARM920: remove exports and forward decls
Unneeded exports cause confusion about the module interfaces.
Make most functions static.  Add a short header comment.

The forward decls are just code clutter; remove them, by moving
their references after definitions.  This is another file which
never needed even one internal forward declaration.

This saved almost 900 bytes of code on x86_32; it seems the
compiler can leverage its knowledge that these functions are
not called from the outside world...

9eb3181cc8 Paulius Zaleckas <paulius.zaleckas@gmail.com>:
This is minimal patch to support FA526 ARMv4 compatible core.
Since it is very similar to ARM920T I tried to reuse as much
code as possible.

CPU and board configs will follow soon.

3acb107b9a - endianess fixes everywhere but in the flash code. flashing might still be broken on big-endian targets and/or hosts
- added access to ARM920T vector catch register (via generic register mechanism)
- don't disable linefills on ARM920T cores - this lead to lockups when accessing lines already contained in cache
- read content of ARM920T cache and tlb into file (arm920t read_flash/read_mmu commands)
- memory reading improved on ARM7/9, can be further accelerated with new "arm7_9 fast_memory_access enable" command (renamed from fast_writes)
- made in_handler independent from in field (makes the handler more flexible)
- added timeout to ft2232 when using D2XX library
- fixed STR7x protection bit handling on second bank (thanks to Bernard)
- added support for using the OpenOCD on AT91RM9200 systems (thanks to Anders Larsen)
- fixed AT91SAM7 flash handling when not running from 32kHz clock (thanks to Anders Larsen)
