PS1, Line 96: 	default 0x5 if BOARD_GOOGLE_SKYRIM
            : 	default 0xffffffff
Does this mean 100mhz only works on skyrim, and not any of the variants?

Is there a bug to track enabling 100mhz on the variants?

PS1, Line 143: endif # !EM100
nit: Move the new values after these default values, to match the guybrush `Kconfig` ordering (and make it easier to find the defaults).
