2017-11-17amd/stoneyridge: Add SlpTyp SMI handlerMarshall Dawson
When an SMI occurs due to SlpType, interpret the type of request being made. If it's S3 or higher, flush the cache and disable further SMIs. Reenable SlpTyp functionality in the ACPI logic and reissue the cycle.

2017-10-02amd/stoneyridge: Refactor SMI handlerMarshall Dawson
Rewrite the handler to be more compact and extendable. The old functionality is duplicated after the rewrite. All SMI source registers (except for SmiSciStatus) behave identically so these are consolidated. Register 0x80 contains sources 0-31, 0x81 sources 32-63, and so on. Create a table of mini-handlers to be supported in the soc directory. As SMI sources are discovered, attempt to find the corresponding handler and then execute it.

2017-10-02amd/stoneyridge: Check SMI command address before readingMarshall Dawson
Use the currently programmed address of the SMI command port before checking the passed command. This ensures we're reading the right port in case the port was relocated without our knowledge.

2017-09-27amd/stoneyridge: Enable SMM in TSEGMarshall Dawson
Add necessary features to allow mp_init_with_smm() to install and relocate an SMM handler. SMM region functions are added to easily identify the SMM attributes. Adjust the neighboring cbmem_top() rounding downward to better reflect the default TSEG size. Add relocation attributes to be set by each core a relocation handler. Modify the definition of smi_southbridge_handler() to match TSEG prototype.

2017-06-27soc/amd/stoneyridge: Fix most checkpatch errorsMarshall Dawson
Correct the majority of reported errors and mark most of the remaining ones as todo. (Some of the lines requiring a >80 break are indented too much currently.) Some of the alignment in hudson.h still causes checkpatch errors, but this is intentionally left as-is. Also make other misc. changes, e.g. consistency in lower-case for hex values, using defined values, etc. These changes were confirmed to cause no changes in a Gardenia build. No other improvements were made, e.g. changing to helper functions, or converting functions like __outbyte().
