ARM DS 5 script to initialize and load code in SDRAM

This is interesting, I'm working with a Cyclone V board but there isn't a board specific example how to use hardware.

The HPS has 2 ddr3 SRDAM chips and the FPGA also has 2 DDR3 SdRAM chips.

How do we write to the controller in binary mode using a constant pointer?

I'd like to load up SDRAM but be able to write the hardware based on bytes in SDRAM.

There was no hardware library for this board, so I have to implement constant pointers to registers.

Is there SDRAM0 and SDRAM1 variables or what are the variables used in ARM DS-5 for all hardware?
