Change subject: lib/fmap: Allow disabling all output in fmap cache ......................................................................
Patch Set 1:
This seems a bit too specific to remove only these messages and no others if you ask me. I think either the platform should select NO_BOOTBLOCK_CONSOLE or NO_FMAP_CACHE (CB:36937).
Note that for the most part, we leave strings in when we reduce the log level, so this mechanism is different from our normal verbosity selection mode (which merely makes printk decide whether to print a string or not).
Yeah, that's also something we should really fix at some point I think, it would be much better than disabling consoles all-or-nothing.
