[Karthik Ramasubramanian (Code Review)]

Hello build bot (Jenkins), Furquan Shaikh, Marco Chen,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/40531

to look at the new patch set (#3).

Change subject: mb/google/dedede: Remove pad termination for RAM_STRAP_4

mb/google/dedede: Remove pad termination for RAM_STRAP_4

The stuffed resistor straps are weaker compared to the internal pull-up.
This can cause the GPIO to read '1' always. Remove the internal pull-up.
Also read the GPIO only on the boards where the board version is
populated.

BUG=b:154301008
TEST=Build and boot the mainboard.
