* dsp563xx: rudimentary gdb supportMathias K2011-02-211-206/+477
| | | | | | | | | | | This patch add rudimentary gdb support. The gdb register list order is corrected. All registers are now 32bit width. Events are send to signalize gdb the current target status. Resume and step function was corrected to consider a modified pc register. Read/write memory now support L memory type, this means a memory with alternating y/x memory words. The memspace variable, used by gdb, is now observed before a default memory access is initiated. Dummy functions for breakpoint and watchpoint are added.
* dsp563xx: minor fixes, code cleanupMathias K2011-02-171-52/+110
| | | | | | | | This patch move the dsp563xx_target_create function to the related code block. Also the target examine function was added and the register cache is initialized in a separate function. The missing functionality to invalidate the x memory context on memory writes was also added.

* dsp563xx: add x, y and p memory accessMathias K2011-02-081-65/+303
| | | | | | | | | | | Hello, this patch add commands to access to x,y and p memory. For run time optimization some local jtag function was changed to static inline. Regards, Mathias
* more changes to dsp563xx codeMathias K2011-02-031-404/+724
| | | | | | | | | | | | | Hello, this patch adds the missing cpu registers and the correct read/write register functions and fixed most of the halt/step/resume issues. The complete missing error propagation was added. + fix tab/spaces Regards, Mathias

* jtag: cut down on usage of unintended modification of global end stateØyvind Harboe2010-03-181-4/+2
| | | | | | | | | | | | | 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.

* jtag: simplify jtag_add_plain_ir/dr_scanØyvind Harboe2010-03-081-12/+2

* jtag: retire tap fieldØyvind Harboe2010-03-081-2/+0
| | | | | | | | | | | | | | | | | 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>
* fix crash with DSP563XXMathias Kuester2010-02-141-0/+25
| | | | | | | | | | | When a DSP563xx-aware GDB asks OpenOCD for target registers, the result should be a GDB with register data ... not an OpenOCD crash. (Note that mainline GDB doesn't currently support this core, so for now, this requires a GDB with FreeScale patches.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
