It seems like all SDK code is for the MCUXpresso or IAR.
The code (neither C nor assembly) does not compile using the GHS compiler/assembler, and conversion is not easy.
Does NXP provide BSPs for the GHS tool set?
No, NXP by itself does not provide any BSP/SDK for the Green Hills RTOS/tools. Please contact Green Hills directly for that:

Have a great day,
