PS1, Line 112: 
             : # Newer SoC have the menvconfig register.
             : # Very few SOC do not have this.
             : # Older SoC, such as the SiFive FU[57]40, that
             : # do not have this register, should set this
             : # to n.
Typically I'd suggest that this text go into a "help" section, but there's no prompt here, so I'm not sure whether or not it matters.

Anyone else have an opinion?
