Rampayload: Able to build coreboot without ramstage
This patch removes all possible dependencies in order to build platform with CONFIG_RAMPAYLOAD enable(without ramstage). A. Create coreboot separate stage kconfigs This patch creates seperate stage configs as below 1. HAVE_BOOTBLOCK 2. HAVE_VERSTAGE 3. HAVE_ROMSTAGE 4. HAVE_POSTCAR 5. HAVE_RAMSTAGE B. Also ensures below kconfigs are aligned with correct stage configs 1. COMPRESS_RAMSTAGE and RELOCATABLE_RAMSTAGE are now enable if CONFIG_HAVE_RAMSTAGE is selected. 2. COMPRESS_BOOTBLOCK will enable if CONFIG_HAVE_BOOTBLOCK is set 3. COMPRESS_PRERAM_STAGES will enable if CONFIG_HAVE_VERSTAGE || CONFIG_HAVE_ROMSTAGE is selected. C. Also fix compilation issue with !CONFIG_HAVE_RAMSTAGE On x86 platform: Case 1: ramstage do exist: CONFIG_HAVE_RAMSTAGE=1 >> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_x86_32 Case 2: ramstage doesn't exist: CONFIG_HAVE_RAMSTAGE=0 >> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_ This patch fixes Case 2 usecase where platform doesn't select CONFIG_HAVE_RAMSTAGE. Also add option to create sipi_vector.manual based on $(TARGET_STAGE) variable. $(TARGET_STAGE)=ramstage if user selects CONFIG_HAVE_RAMSTAGE $(TARGET_STAGE)=postcar if user selects CONFIG_RAMPAYLOAD Change-Id: I0f7e4174619016c5a54c28bedd52699df417a5b7 Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/33142 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
