PS7, Line 275: print("Vio18 = %d\n", dramc_get_vio18_voltage());
> vio18 is fixed at 1.8 volts, it will not be adjusted during dram init, […]

So it'll simply show 0? given it's only for debugging I think it's probably fine?

If you really want to remove it, please add a comment in the description for example

Add the implementation for vcore voltage control.
 Also remove the reporting of vio18 because it is fixed during DRAM init,
 and we won't provide drivers for reading or writing it.
