[coreboot] Quick question for Kconfig lint checking

[Prajapati, Pratikkumar V]

Hello,

Quick question for Kconfig lint checking!

For my patch https://review.coreboot.org/c/coreboot/+/71120, the Jenkins build fails with following error:

"Check Kconfig files for errors (lint-stable-008-kconfig): #!!!!! Error: 'CONFIG_SOC_INTEL_COMMON_BLOCK_PRMRR_SIZE_2MB' selected at src/soc/intel/meteorlake/Kconfig:101.  Symbols created in a choice cannot be selected"

What is the rationale behind enforcing this? As of now, PRMRR Kconfig settings are in common code and i wanted to set the right size from SOC specific code. e.g. the patch i mentioned earlier.

Should we get rid of enforcing "lint-stable-008-kconfig" test? If not what is the best way to achieve the scenario i mentioned above.

One option i think is to simplify PRMRR Kconfig options (get rid of choice menu) and define PRMRR_SIZE config option in SOC specific code. But then all SOC specific code would have to define this Kconfig option. If some SOC does not need PRMRR then also the Kconfig option with default set 0 might be needed.

Thanks for suggestions in advance.
