QSPI flash support

The J-Link DLL also supports programming of any (Q)SPI flash connected to a device
that is supported by the J-Link DLL, if the device allows memory-mapped access to
the flash. Most modern MCUs / CPUs provide a so called "QSPI area" in their mem-
ory-map which allows the CPU to read-access a (Q)SPI flash as regular memory
(RAM, internal flash etc.).
6.7.1 Setup the DLL for QSPI flash download
There is nothing special to be done by the user to also enable download into a QSPI
flash connected to a specific device. The setup and behavior is the same as if down-
load into internal flash, which mainly means the device has to be selected and noth-
ing else, would be performed. For more information about how to setup the J-Link
DLL for download into internal flash memory, please refer to Setup for various debug-
gers (internal flash) on page 251.
The sectorization, command set and other flash parameters are fully auto-detected
by the J-Link DLL, so no special user setup is required.
