2022-12-07mb,sb,soc/intel: Drop useless IO trap handlersKyösti Mälkki
There are four requirements for the SMI to hit a printk() this commit now removes. Build must have DEBUG_SMI=y, otherwise any printk() is a no-op inside SMM. ASL must have a TRAP() with argument 0x99 or 0x32 for SMIF value. Platform needs to have IO Trap #3 enabled at IO 0x800. The SMI monitor must call io_trap_handler for IO Trap #3. At the moment, only getac/p470 would meet the above criteria with TRAP(0x32) in its DSDT _INI method. The ASL ignores any return value of TRAP() calls made. A mainboard IO trap handler should have precedence over a southbridge IO trap handler. At the moment we seem to have no cases of the latter to support, so remove the latter.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.
