#################### General Notes ########################
# Our controller support both DDR4 and GDDR5, we need to "modify" ext_ram_columns in the following way:
#   For DDR4, need to use column number as in DRAM Data Sheet, meaning 1024 in drams supported.
#   For GDDR5, need to multiply number in Data Sheet by 8 (representing the 3 address bits, which are constant 000 in DDR4.), meaning 512 in drams supported.
