Native raminit is to replace the Intel provided closed source binary, that does initialize the memory. This binary is referenced as MRC (Memory Reference Code). Some platforms do support either MRC or native raminit, others only support one of them. In general one can summarize that DDR3 or DDR4 raminit is much more complex that DDR2 raminit, make it more difficult to provide open source and bug free raminit code.

Native raminit is to replace the Intel provided closed source binary, that does initialize the memory. This binary is referenced as MRC (Memory Reference Code). Some platforms do support either MRC or native raminit, others only support one of them. In general one can summarize that DDR3 or DDR4 raminit is much more complex that DDR2 raminit, make it more difficult to provide open source and bug free raminit code.
