2017-09-27amd/stoneyridge: Clean up include files in northbridge.hMarshall Dawson
Add an extra include file to northbridge.c for completeness. cpu/msr.h is already included in cpu/amd/mtrr.h which allows the file to build properly. Remove include files that are no longer required for the file.

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.

2017-09-27amd/stoneyridge: Convert MP init to mp_init_with_smmMarshall Dawson
Change the Stoney Ridge SOC to a more modern method for setting up the multiple cores. Add a new cpu.c file for most of the processor initiliazation. Build mp_ops with the necessary callbacks. Note also that this patch removes cpu_bus_scan. Rather than manually find CPUs and add them to the devicetree, allow this to be done automatically in the generic mp_init.c file. SMM information is left blank in mp_ops to avoid having mp_init.c install a handler at this time. A later patch will add TSEG SMM capabilities for the APU. This patch also contains a hack to mask the behavior of AGESA which configures the MTRRs and Tom2ForceMemTypeWB coming out of AmdInitPost. The hack immediately changes all WB variable MTRRs, on the BSP, to UC so that all writes to memory space will make it to the DRAM.

2017-09-13amd/stoneyridge: Remove multi-node supportMarshall Dawson
The Stoney Ridge APU can never be used in a multi-node system. Reduce the feature set to a single node. Remove the static variables for each D18Fn device and replace the routines with coreboot config read and write functions. Strip down domain_set_resources() to consider only a single node. A follow-on patch will further simplify this.

2017-09-13amd/stoneyridge: Simplify SB link routingMarshall Dawson
Remove the check for the southbridge link from Stoney Ridge. The APU is an SoC which can never be installed in a multi-node system. It is pointless to detect and remember the sblink value, which is set by hardware and comes up 0. The BKDG marks this as a reserved field vs. documentation for multi-node-capable Family 15h devices. Because there is only one option for SB link now, relocate the register write done by set_vga_enable_reg() and remove the function.

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().
