2010-07-02initial "transport" frameworkDavid Brownell
This adds the guts of a transport framework with initialization, which should work with current JTAG-only configurations (tested with FT2232). Each debug adapter can declare the transports it supports, and exactly one transport is initialized. (with its commands) in any given OpenOCD session. * Define a new "struct transport with init hooks and a few "transport" subcommands to support it: "list" ... list the transports configured (just "jtag" for now) "select" ... makes the debug session use that transport "init" ... initializes the selected transport (internal) * "interface_transports" ... declares transports the current interface can support. (Some will do this from C code instead, when there are no hardware versioning (or other) issues to prevent it. Plus some FT2232 tweaks, including a few to streamline upcoming support for an SWD transport (initially for Luminary adapters). Eventually src/jtag should probably become src/transport, moving jtag-specific stuff to transport/jtag. Signed-off-by: David Brownell <db@helium.(none)>

2010-05-05command context: fix errors when running certain commands on startupØyvind Harboe
Various commands, e.g. "arm mcr xxxx" would fail if invoked upon startup since it there was no command context defined for the jim interpreter in that case. A Jim interpreter is now associated with a command context(telnet, gdb server's) or the default global command context. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

2010-03-27jtag/tcl.c cleanup -- split out "adapter.c"David Brownell
Clean up the jtag/tcl.c file, which was one of the biggest and messiest ones in that directory. Do it by splitting out all the generic adapter commands to a separate "adapter.c" file (leaving the "tcl.c" file holding only JTAG utilities). Also rename the little-used "jtag interface" to "adapter_name", which should have been at least re-categorized earlier (it's not jtag-only).

2010-03-21ft2232 init mess cleanupDavid Brownell
In the ft2232 driver, initialization for many layouts punts to a routine called usbjtag_init(), instead of a routine specific to each layout. That routine is a mess built around a "what type layout am I" core. That's a bad design ... in this case, especially so, since it bypasses the layout-specific dispatch which was just done, and obfuscates the initialization which is at least somewhat generic, instead of being specific to the "usbjtag" layout. Split and document out the generic parts of usbjtag_init(), and make the rest of those layouts have layout-specific init methods. Also, rename usbjtag_reset() ... that also was not specific to the "usbjtag" layout, and thus contributed to the previous code structure confusion. (Eventually, all layout-specific code (and method tables) should probably live in files specific to each layout. These changes will facilitate those and other cleanups to this driver.)

2010-03-19jtag: remove jtag_get_end_state()'s that should be unecessaryØyvind Harboe
By a bit of code inspection it seems like all of these instances of jtag_get_end_state() can be unambigously replaced by constants. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-03-18jtag: cut down on usage of unintended modification of global end stateØyvind Harboe
jtag_get/set_end_state() is now deprecated. There were lots of places in the code where the end state was unintentionally modified. The big Q is whether there were any places where the intention was to modify the end state. 0.5 is a long way off, so we'll get a fair amount of testing.

2010-03-15move "reset_config" out of JTAG command groupDavid Brownell
The SRST configuration options are not specific to JTAG, so this command may be needed with non-JTAG debug sessions. Just move the command to a different group. (The TRST options are, however, clearly JTAG-specific, but for compatibility, they're now left alone. The flags they control could later be disabled in non-JTAG sessions.)
