Commit c8926d1457 introduces the
context and hybrid breakpoint types beside existing SW and HW
types. The new field "asid" is non-zero only for these new types.
The commit above did not properly initialize "asid" to 0 for a
temporarily HW breakpoint used during single step. This causes
cortex_a_unset_breakpoint() to identify this breakpoint as of
type "hybrid".
Identified through valgrind error:
Conditional jump or move depends on uninitialised value(s)
Actually valgrind triggers a total of 10 messages about use of
uninitialized variables, but they are all caused by the first
conditional jump bases on "asid != 0".
Fixed by initializing "asid" to 0 in cortex_a_step().
Fixes: c8926d1457 ("cortex_a hybrid & context breakpoints")

Commit 0057c71ab6 updates the OpenOCD
cached values of CSW and TAR registers if these registers are modified
by an apreg command.
The condition to force the update of CSW cache is incorrect and it will
erase the default CSW value.
Moreover, calling mem_ap_setup_csw() does not honor the value requested
in the apreg command because such value is incorrectly bitwise or-ed
with csw_default.
Fix it by updating csw_value, instead of erasing csw_default, and writing
directly in CSW register the new value from the command line.

a number of additional changes to support non-linear register numbers
and the 'p' packet in RTOS support for proper integration into

This patch adds support for p packet responses by targets configured

which is similar to struct reg used by targets, which resulted in
needing to update each stacking with register numbers. This patch also

as well.

Commit 5aceec2412 ("drivers:
cmsis-dap: pull up common connect code") breaks the driver and it
cannot connect anymore in JTAG mode.
The issue is caused in cmsis_dap_init() by anticipating the call to
cmsis_dap_usb_open(), which then sets cmsis_dap_handle and makes the
following test to always fail.
Actually the original code was quite tricky:
if (swd_mode)
do something that also sets cmsis_dap_handle;
if (cmsis_dap_handle == NULL)
do something for !swd_mode;
Convert the sequence of tricky "if"s in a single "if-then-else" to
handle clearly the cases swd_mode and !swd_mode.

Virtual targets, like mem_ap, do not or cannot implement the required
functionality to accept a GDB connection. In the case of mem_ap, the
method get_gdb_reg_list() is missing and a following connection from
gdb causes OpenOCD to segfault.
OpenOCD opens a GDB port for each target; it's always possible to
connect, by mistake, GDB to one virtual target.
Add a method to check if the target supports GDB connections (for the
moment just checking if get_gdb_reg_list is implemented).
Skip opening a gdb server for every targets that don't support GDB
connections.
