Enable FPGA-to-HPS SDRAM Interface

Hi @jackfrye11

Do you think the issue was down to the u-boot version or the embedded SoC shell tools? If the build process is like the Arria 10 one then the embedded shell tools generate the u-boot device tree. Did you see if this device tree changed between embedded shell tool versions? If not then it must be a u-boot fix.

Interesting findings. Glad you got it working in the end.

My guess is embedded_command_shell since the generated directory from that bsp_create_settings command has a <handoff_directory>/sdram/sdram.h file that includes what appear to be correct values for the macros when generated by 20.1 tools, whereas they seem to have the wrong value for 19.1
