Adds a target driver for Microchip SAM D51 / E5x family.
Tested on SAMD51G19A and SAMD51J19A. According to the datasheet, the
D51 / E5x family share the same core feature set, differing only in the
addition of CAN (E51) or ethernet controllers (E53/54). All members of
the family should be equivalent from a debug and programming perspective.
Support for Kinetis KE04 8KiB, 64KiB and 128KiB variants in nxpke04.c
Target monitor commands for sector and mass erase.
Changes to kinetis.c MDM-AP target to support KE04.
Only KE04Z8 tested in HW.
This adds a new function to the internal target interface
to allow the target to get control before reset is complete
so that it can do any additional work. On this target there
is a proprietary internal bit that has to be reset in some
cases to allow the core to continue operating.
The new function returns a stop reason which must be translated in gdb server.
In the case of a watchpoint hit, the address is returned by a pointer parameter.
Simplify the extenal interface for set/clear breaki-/watchpoints.
