Thanks for all that, Matt. A little perspective helps me a lot!
I'm wondering, with MrChrombox coreboot will anything normally show on a chromebook screen at ramstage, before payload? Or, if not, can anything be *made* to show on the screen, like status or debug info? I'm thinking, if a payload fails, at least something on the screen from coreboot ramstage would indicate that coreboot executed up through ramstage, without needing to connect a debug cable - and sort of geek eye-candy.
Also, it looks like there is a way to save coreboot debug messages to a file. But, does that use CAR, or would messages be repeatedly written to the ROM with every boot? Maybe cache is too small to use for debug messages - geminilake? Or repeatedly writing to ROM reduces its life?
