      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.

      Remove most remaining uses of target->arch_info from ARM

      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)

      - 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)
