Are we sure we want to completely override it rather than adding to it? I'd be rather irritated if this blows away my prompt without my asking for it. I think either it should append or have a variable controlling whether this is enabled when building the SDK.

The default assignment of SDK_PS1 is '?=', you can set it in conf file to override it.

Regards,
Kai

Introduce a new variable SDK_PS1 to customize prompt string for SDKs
when source script environment-setup-script.

The default prompt string of SDKs looks like:

SDK-poky-glibc-x86_64--cortexa57-qemuarm64$
