Flash Breakpoints in QSPI flash

Many modern CPUs allow direct execution from QSPI flash in a so-called "QSPI area"
in their memory-map. This feature is called execute-in-place (XIP). On some cores
like Cortex-M where hardware breakpoints are only available in a certain address
range, sometimes J-Link flash breakpoints are the only possibility to set breakpoints
when debugging code running in QSPI flash.
7.5.1 Setup
The setup for the debugger is the same as for downloading into QSPI flash. For more
information please refer to QSPI flash support on page 260.
