This string holds the full part number of the SoC. It is a hidden option
that you should not set directly. The part number selection choice defines
the default value for this string.

Selects the amount to divide the VCO output of the PLL. The VDIV 0 bits
establish the multiplication factor (M) applied to the reference clock
frequency.
