2018-10-31soc/amd/stoneyridge: Fix get_cpu_count()Martin Roth
In commit 41baf0c3ff (soc/amd/stoneyridge: Remove dev_find_slot where possible), the register being read was changed accidentally from HT_DEV (Device 18h, Func 0) to NB_DEV (Device 18h, Func 5) This doesn't return the correct value, and causes Grunt to reboot.

2018-10-30soc/amd/stoneyridge: Remove dev_find_slot where possibleRichard Spiegel
The procedure dev_find_slot has 3 main uses. To find configuration (devicetree), to verify if a particular device is enabled at build \ time, and to get the address for PCI access while in bootblock/romstage. The third use can be hidden by using macros defined in pci_devs.h, making it very clear what PCI device is being accessed. replace the temporary pointers to device used with PCI access with SOC_XXX_DEV where XXX is the device being accessed, and remove the setting of the temporary pointers. BUG=b:117917136 TEST=Build grunt.

2018-08-08amd/stoneyridge: Add warm reset detectionMarshall Dawson
Extend the existing reset handling features in Stoney Ridge to plan for, and recognize, warm resets. The ColdRstDet bit is always zero on a cold reset, and is intended as a mechanism for the BIOS to determine the type of a reset that occurred. Set ColdRstDet=1 after all cores have been initialized, so that any subsequent reset may be identified as warm/cold. A later patch will check the value during mp_init.

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.

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.
