This PR will change the default runner for these boards to be Linkserver. Please update the documentation for these boards to clarify that the default runner is now Linkserver- see the RT1170 documentation page for an example of how we document Linkserver usage: https://github.com/zephyrproject-rtos/zephyr/blob/main/boards/arm/mimxrt1170_evk/doc/index.rst#using-linkserver (note that on this board we will not need to set the runner to linkserver with -r

I was wrong- the linkserver debugger definition will not set itself as the default, so the board default here is still JLink

Can you please update the board documentation for these boards to call out that Linkserver is now supported as a runner? You can look at the RT1170 doc page I linked for an example

@butok , this looks good. Can you please update the board documentation to indicate this support.

It is needed to prove that LinkServer is mature enough.
My plan:

• add .hex LinkServer support nxp: LinkServer runner does not support applications with an adjusted LMA address #63734.
• check LinkServer "west debug".
• update the documentation

If failed, to reformat/cancel this commit and to leave jlink as a default runner.
