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
