This is a complete rewrite of my earlier stack checker proposal. It works for CAR and RAM, has better abstraction and actually gives us nice results. The stack checker is default off due to its rather measurable impact on boot speed. Diagnostic messages are printed on first initialization, directly after RAM init and directly before passing control to the payload. Sample qemu log is attached. Extract from that log follows: coreboot-3.0.986 Fri Nov 7 04:04:37 CET 2008 starting... (console_loglevel=8) Initial lowest stack is 0x0008fe98 Choosing fallback boot. [...] Done RAM init code After RAM init, lowest stack is 0x0008fe30 Done printk() buffer move [...] LAR: load_file_segments: Failed for normal/payload Before handoff to payload, lowest stack is 0x0008bf50 FATAL: No usable payload found.
