soc/intel/meteorlake: Use coreboot native event handler for FSP-M/S
This patch assigns FSP handler event for FSP-M and FSP-S with coreboot romstage and ramstage debug handler when FSP_USES_CB_DEBUG_EVENT_HANDLER Kconfig is enabled. BUG=b:237263080 TEST=Able to build and boot MTL simics. Also, verified the FSP debug log is using coreboot debug library as below: Before: Register PPI Notify: DCD0BE23-9586-40F4-B643-06522CED4EDE Install PPI: 8C8CE578-8A3D-4F1C-9935-896185C32DD3 Install PPI: 5473C07A-3DCB-4DCA-BD6F-1E9689E7349A The 0th FV start address is 0x000F961B000, size is 0x00150000, handle is 0xF961B000 Register PPI Notify: 49EDB1C1-BF21-4761-BB12-EB0031AABB39 Register PPI Notify: EA7CA24B-DED5-4DAD-A389-BF827E8F9B38 Install PPI: B9E0ABFE-5979-4914-977F-6DEE78C278A6 With this code change: [SPEW ] Register PPI Notify: DCD0BE23-9586-40F4-B643-06522CED4EDE [SPEW ] Install PPI: 8C8CE578-8A3D-4F1C-9935-896185C32DD3 [SPEW ] Install PPI: 5473C07A-3DCB-4DCA-BD6F-1E9689E7349A [SPEW ] The 0th FV start address is 0x000F95C0000, size is 0x00160000, handle is 0xF95C0000 [SPEW ] Register PPI Notify: 49EDB1C1-BF21-4761-BB12-EB0031AABB39 [SPEW ] Register PPI Notify: EA7CA24B-DED5-4DAD-A389-BF827E8F9B38 [SPEW ] Install PPI: B9E0ABFE-5979-4914-977F-6DEE78C278A6 Signed-off-by: Subrata Banik <subratabanik@google.com> Change-Id: I80ba73afed642e6d21c5310e9bf734f6f7170347 Reviewed-on: https://review.coreboot.org/c/coreboot/+/65456 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Eric Lai <eric_lai@quanta.corp-partner.google.com>
