2017-10-19soc/amd/stoneyridge: Replace magic registersRichard Spiegel
Replace southbridge registers and register values from magic numbers to literals, provided these registers are currently defined publicly or in NDA datasheet. Registers available only internally to AMD are left unchanged.

2017-10-15soc/amd/stoneyridge/lpc.c: Refactor lpc_enable_childrens_resourcesRichard Spiegel
Factor out the code into separate functions. Create set_lpc_resource that will set the resource for a particular child while lpc_enable_childrens_resources finds all children and calls set_lpc_resource for each child found. This creates well defined boundaries for each function.

2017-09-20vboot: remove init_vbnv_cmos()Aaron Durbin
Instead of having each potential caller deal with the differences of cmos_init() and init_vbnv_cmos() when VBOOT is enabled put the correct logic within the callee, cmos_init(), for handling the vbnv in CMOS. The internal __cmos_init() routine returns when the CMOS area was cleared.

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().
