2018-05-23soc/amd/stoneyridge/: Get rid of device_tElyes HAOUAS
Use of device_t has been abandoned in ramstage.

2018-04-11amd/stoneyridge: Reorder temp mtrr for flashMarshall Dawson
Relocate setting the temp range MTRR, for the SPI flash device, to after completion of mp_init. The mp_init functionality mirrors the BSP's exact MTRR settings into the AP cores. The ranges need to be the correct calculated values and not some temporary setting. This solves an MTRR sync issue on APUs with more than two cores, i.e. more than a single compute-unit. MTRRs within a CU are shared so the AP always stays in sync.

Move the remaining model_15_init.c functionality to cpu.c, making it similar to other soc implementations.

2018-01-31amd/stoneyridge: Move TValid and SmmLock to end of POSTMarshall Dawson
Delay making TSEG valid until the end of POST. After the CPU setup, there are times where coreboot needs to access the SMRAM from outside of SMM. Also relocate locking of the SMM settings from the CPU init to the end of POST (or just before resuming).

2018-01-12amd/stoneyridge: Keep SPI flash cacheable during POSTMarshall Dawson
A side effect of using the common MTRR assignment code is the flash device loses its WP setting and is no longer cacheable. After MTRR setup, reenable the setting for the duration of POST.

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.
