* command context: fix errors when running certain commands on startupØyvind Harboe2010-05-051-2/+2
| | | | | | | | | | | 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>

* jtag/tcl.c cleanup -- split out "adapter.c"David Brownell2010-03-274-430/+466
| | | | | | | | | | | | 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).

* ft2232 init mess cleanupDavid Brownell2010-03-211-60/+99
| | | | | | | | | | | | | | | | | | | | | | 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.)

* jtag: remove jtag_get_end_state()'s that should be unecessaryØyvind Harboe2010-03-191-1/+1
| | | | | | | | 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>
* jtag: cut down on usage of unintended modification of global end stateØyvind Harboe2010-03-182-4/+8
| | | | | | | | | | | | | 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.

* move "reset_config" out of JTAG command groupDavid Brownell2010-03-151-11/+11
| | | | | | | | | | | | 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.)

* FT2232: lookup and save layout just onceDavid Brownell2010-03-141-31/+39
| | | | | | | | | | | | | | Streamline use of the layout: have the "ft2232_layout" command look it up and save the result, instead of having a few different chunks of code looking it up later, and saving just its name (which is already part of the layout). This - is cleaner - reports errors sooner - facilitates earlier adapter-specific setup - removes unused "default to "usbjtag" logic Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* split "interface" commands from "jtag" onesDavid Brownell2010-03-112-5/+25
| | | | | | | | | | | | | | | | | | | | | | | | | We'll need to be able to work with debug adapter interfaces (drivers) even when they're not used for JTAG ... for example, while there are multi-transport drivers which support JTAG *and* several other transports (or just one more, like SWD) there are also adapters with more limited goals (and no JTAG support at all). Start decoupling the two concepts ("debug adapter driver", "jtag") by having two command groups, which initialize separately. This will help us support OpenOCD sessions using only non-JTAG transports, in which JTAG commands should not be registered. Update docs to mention that the JTAG, SVF, and XSVF commands won't work without a JTAG transport. Note that at least commands working with SRST are still inappropriately coupled to JTAG ... inappropriate because (a) SRST is not part of the JTAG standard, for all that many platforms (like ARM) expect it; and also (b) because they're used with non-JTAG debug and programming interfaces, too. They should perhaps become generic "interface" operations at some point. (Similarly with the clock rate to be used by a given adapter.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* jtag: jtag_add_ir_scan() now takes a single fieldØyvind Harboe2010-03-087-26/+35
| | | | | | | | In the code a single field was all that was ever used. Makes jtag_add_ir_scan() simpler and leaves more complicated stuff to jtag_add_plain_ir_scan(). Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: retire tap fieldØyvind Harboe2010-03-087-113/+52
| | | | | | | | | | | | | | | | | jtag_add_dr/ir_scan() now takes the tap as the first argument, rather than for each of the fields passed in. The code never exercised the path where there was more than one tap being scanned, who knows if it even worked. This simplifies the implementation and reduces clutter in the calling code. use jtag_add_ir/dr_plain_scan() for more fancy situations. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
