Unfortunately, this script is not available but you could try checking the SDRAM initialization in the BOARD_InitSDRAM (you can check this function in the ew_gui examples in the SDK) and check the register written in the example and use the same script to write the configurations.
I already program the EMC on my own designs for SDRAM, it was more that I thought that something as basic as this would already be available from NXP :smileyhappy:
