      ETM: remove old mid-level ETM handle · 5723e54f
      David Brownell authored 
      

Now that nothing uses the old ETM handle any more, remove it.
Add minimal header tweaks, letting non-ARM7 and non-ARM9 cores
access ETM facilities.

Now ARM11 could support standard ETM (and ETB) access as soon as
it derives from "struct arm" ... its scanchain 6 is used access
the ETM, just like ARM7 and ARM9.

The Cortex parts (both M3 and A8) will need modified access methods
(via ETM init parameters), so they use the DAP.  Our first A8 target
(OMAP3) needs that for both ETM and ETB, but the M3 ETM isn't very
useful without SWO trace support (it's painfully stripped down), so
that support won't be worth adding for a while.

      finish removing deprecated/obsolete commands · d70d9634
      David Brownell authored 
      

It's been about a year since these were deprecated and, in most
cases, removed.  There's no point in carrying that documentation,
or backwards compatibility for "jtag_device" and "jtag_speed",
around forever.  (Or a few remnants of obsolete code...)

Removed a few obsolete uses of "jtag_speed":

 - The Calao stuff hasn't worked since July 2008.  (Those Atmel
   targets need to work with a 32KHz core clock after reset until
   board-specific init-reset code sets up the PLL and enables a
   faster JTAg clock.)
 - Parport speed controls don't actually work (tops out at about
   1 MHz on typical HW).
 - In general, speed controls need to live in board.cfg files (or
   sometimes target.cfg files), not interface.cfg ...

      ARM: shrink offsets · 6a0af06b
      David Brownell authored 
      

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.

      ARM: other code uses the new inheritance/nesting scheme · 03ac53a2
      David Brownell authored 
      

Remove most remaining uses of target->arch_info from ARM
infrastructure, where it hasn't already been updated.

      target: provide container_of() · db116b1e
      David Brownell authored 
      

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).

      Cleanup some the downloaded ARM target algorithm code:

 - Provide more complete disassembly of the DCC bulk write code

 - Make code blocks "static const", in case GCC doesn't

 - Fix some tabbing/layout issues

 - Make some arm7_9_common.h flags be "bool" not "int"; and compact
   the layout a bit (group most bools together)
