Hi,
I am using Open OCD tool chain to debug the code and H-JTAG to flash the
AT91SAM7S256 (Atmel - ARM based) controller. I have two queries on
flashing the code into AT91SAM7S256
1. There are two locations where I can flash the code. One is at
0x00 and the other is at 0x10. What
So the minidriver (including classic API) must have control over whether or
not the following fn's gets inlined or not. These fn's really are in the inner

system.
Note that I'm not keen on the idea of an ABI for OpenOCD, we need

You don't explain why this is necessary and I don't agree. I believe
you assume that it is impossible to allow the minidriver to inline

Actually, I did just find two things:

I added a missing #include sys/stat.h, but it is not quite ready to commit

I don't think we should try to make this work under anything but POSIX
API for now, but the build should not fail. Autotools magic?

Another issue: runtest is broken now too ... your target: factor init
to 'target init' patch broke it by previnting JTAG event handlers from
using methods like runtest (which is essential for some platforms).
I'm checking in the following patch, since it fixes the regression,
but I'm not sure
For the bits now defined in arm_dpm.h, switch to the
shared DSCR_* symbol and remove the ARM11_DSCR_* version.
Define DSCR_INT_DIS and use it instead of the ARM11_DSCR_*
sibling symbol. (Note: for both ARM11 and Cortex-A8, this
should arguably be enabled by default when single stepping.)
Move the symbols for these bits from armv7a.h to arm_dpm.h,
where they can be seen and used not just by Cortex-A but also
by the ARM11 (armv6) code.
Change them from bit numbers to bit masks ... this matches the
usage in ARM11 code, and also makes it easier to read.
Rename DSCR_EXT_INT_EN as
No point in both ARM11 and Cortex-A8 having private copies
of the logic sorting out e.g. DBG_REASON_WATCHPOINT.
Add and use a shared routine for this ... there's actually
a bunch more debug entry logic that could be shared, this
is just a start on that. Note that this routine fixes a
bug

The newly moved flash TCL routines access the internals of the module
too much. Fix the layering issues by adding new core NOR flash APIs:
flash/nor/core.h:
- flash_driver_find_by_name() - self-descriptive
flash/nor/imp.h:
- flash_bank_add()- encapsulates adding banks to bank
After previous efforts, only one Jim routine remained in jtag/core.c,
and moving it to jtag/tcl.c painlessly finishes separating these layers.
The headers need separating, but the implementation is clean.

Hi all,
The first two patches work to eliminate some Jim handling in the
helper and JTAG modules, with the later being nearly purged.
If the command layer provides some wrappers for Jim's return
handling mechanisms, then all handlers can be converted to use the
high-level command mechanisms --
