2018-09-11amd/stoneyridge: Set BERT region size when no TSEG usedMarshall Dawson
Expand the BERT reserved region size setting to account for the possibility of no TSEG configuration. This change is only for completeness, as stoneyridge must always use TSEG.

2018-09-07amd/stoneyridge: Adjust memory map for reservedMarshall Dawson
Carve out memory to be reported to the OS as reserved. This makes room for a region usable for Boot Error Record Table information. The BERT region reserved size is larger than likely requried, however the SMM region's base must be on a boundary matching the granularity of its size. BUG=b:65446699 TEST=inspect BERT region, and dmesg, on full patch stack. Use test data plus a failing Grunt system.

2018-02-07amd/stoneyridge: Put stage cache into TSEGMarshall Dawson
Add a function to allow an external region to be located in TSEG. Select the option to use memory outside of cbmem. Increase the size reserved in TSEG.

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.

2017-09-13amd/stoneyridge: Make cbmem_top SMM awareMarshall Dawson
Make the default for SMM_TSEG_SIZE depend on SMM_TSEG in addition to HAVE_SMI_HANDLER. Change the value returned by cbmem_top() to carve out a range to be used by TSEG. The SMM Mask register has a granularity of 128KB but align the value to 16MB to keep down the number of variable MTRRs required.
