Dear All,

I have a imx7ulpevk board. I changed the on board DRAM with a 4Gb LPDDR3.  I would like to test the memory as much as I can from the A7 CPU core. When I boot up the A7 core with Linux, I found there are some space seems to be reserved for the M4 or for A7/M4 communication . If this is true, is there any method to change? Will it work if I delete the rpmsg reserved memory in the dtsi file?
