Custom SoC

[mksaksms]

@Mluckydwyer I have run the demo on this https://github.com/Xilinx/systemctlm-cosim-demo/blob/master/docs/zynq-7000-getting-started-guide.md and was getting some value in shell using the devmem 0x40000000. I am not sure about the result but the hex value was increasing. Can you pls help me to replace with my custom soc ? I copied the image and necessary files in buildroot/output/images folder but my devmem of custom PL blocks was not working. Whenever I tried devmem it gives text "decode error !" in the other shell.
