However!
It would require dedicating a flash page for the config, and it would require using flashrom (or an equivalent) to change the config. I wouldn't worry about the flash wear - the config wont change frequently. [...] > Or should we just store options as files in cbfs? That seems simplest. That's a neat idea. It's not very compact, but it would work well for a handful of options. If we went with a config file, I propose something very simple - like text lines with "name=value\n". -Kevin -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
