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.
