   6 JTAG Layer:
   7         Support KT-Link JTAG adapter.
   8         Support USB-JTAG, Altera USB-Blaster and compatibles.
   9
  10 Boundary Scan:
  11
  12 Target Layer:
  13         General
  14                 - new "reset-assert" event, for systems without SRST
  15         ARM
  16                 - supports "reset-assert" event (except on Cortex-M3)
  17                 - renamed "armv4_5" command prefix as "arm"
  18                 - recognize TrustZone "Secure Monitor" mode
  19                 - "arm regs" command output changed
  20                 - register names use "sp" not "r13"
  21                 - add top-level "mcr" and "mrc" commands, replacing
  22                   various core-specific operations
  23                 - basic semihosting support (ARM7/ARM9 only, for now)
  24         ARM11
  25                 - Should act much more like other ARM cores:
  26                    * Preliminary ETM and ETB hookup
  27                    * accelerated "flash erase_check"
  28                    * accelerated GDB memory checksum
  29                    * support "arm regs" command
  30                    * can access all core modes and registers
  31                    * watchpoint support
  32                 - Shares some core debug code with Cortex-A8
  33         Cortex-A8
  34                 - Should act much more like other ARM cores:
  35                    * support "arm regs" command
  36                    * can access all core modes and registers
  37                    * watchpoint support
  38                 - Shares some core debug code with ARM11
  39         Cortex-M3
  40                 - Exposed DWT registers like cycle counter
  41                 - vector_catch settings not clobbered by resets
  42                 - no longer interferes with firmware's fault handling
  43         ETM, ETB
  44                 - "trigger_percent" command moved ETM --> ETB
  45                 - "etm trigger_debug" command added
  46         MIPS
  47                 - use fastdata writes
  48         Freescale DSP563xx cores (partial support)
  49
  50 Flash Layer:
  51         'flash bank' and 'nand device' take <bank_name> as first argument.
  52         With this, flash/NAND commands allow referencing banks by name:
  53                 - <bank_name>: reference the bank with its defined name
  54                 - <driver_name>[.N]: reference the driver's Nth bank
  55         New 'nand verify' command to check bank against an image file.
  56         The "flash erase_address" command now rejects partial sectors;
  57                 previously it would silently erase extra data.  If you
  58                 want to erase the rest of the first and/or last sectors
  59                 instead of failing, you must pass an explicit "pad" flag.
  60         New at91sam9 NAND controller driver.
  61         New s3c64xx NAND controller driver.
  62
  63 Board, Target, and Interface Configuration Scripts:
  64         ARM9
  65                 - ETM and ETB hookup for iMX2* targets
  66         Add $HOME/.openocd to the search path.
  67         Handle Rev C of LM3S811 eval boards.
  68                 - use "luminary-lm3s811.cfg" for older boards
  69                 - use "luminary.cfg" for RevC and newer
  70
  71 Core Jim/TCL Scripting:
  72         New 'usage' command to provide terse command help.
  73         Improved command 'help' command output (sorted and indented).
  74         Improved command handling:
  75                 - Most boolean settings now accept any of the following:
  76                   on/off, enable/disable, true/false, yes/no, 1/0
  77                 - More error checking and reporting.
  78
  79 Documentation:
  80         New built-in command development documentation and primer.
  81
  82 Build and Release:
  83         Use --enable-doxygen-pdf to build PDF developer documentation.
  84         Consider upgrading to libftdi 0.17 if you use that library; it
  85                 includes bugfixes which improve FT2232H support.
