PS2, Line 28: cse_fw_update_disable
> why not `cse_fw_update_enable` ?

Assumption is, coreboot enables a feature by default and debug logic look for OEM SECTION if the feature is disabled or not. Hence, so identifier is chosen to reflect it's purpose. When OEM section indicates a feature has to be disabled, then override logic reverts the feature.

In this case, coreboot native logic enables cse fw update, but debug logic will disable the CSE FW update if user disables the feature in the OEM SECTION.
