Change in coreboot[master]: Rampayload: Attempt to boot coreboot without ramstage
by Subrata Banik (Code Review) 07 Aug '23

Subrata Banik has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/34476 ) Change subject: Rampayload: Attempt to boot coreboot without ramstage ...................................................................... Rampayload: Attempt to boot coreboot without ramstage This patch makes below code changes to boot platform with CONFIG_RAMPAYLOAD enable(without ramstage). A. Able to compile ASL code in postcar. B. Also add option to create smm.manual/smmstub.manual based on $(TARGET_STAGE) variable. $(TARGET_STAGE)=ramstage if user selects CONFIG_HAVE_RAMSTAGE $(TARGET_STAGE)=postcar if user selects CONFIG_RAMPAYLOAD C. Avoid compilation of ramstage specific files from x86/Makefile.inc when !CONFIG_HAVE_RAMSTAGE. D. Replace ENV_RAMSTAGE with ENV_PAYLOAD_LOADER to include required functions incase CONFIG_RAMPAYLOAD is enable.
