2022-07-14soc/amd/*: Move apm call out of MP init codeArthur Heymans
This makes it easier to have common code for MP init on AMD systems.

2022-06-20soc/amd/*: Make mtrr decision based on syscfgArthur Heymans
The syscfg has to option to automatically mark the range between 4G and TOM2, which contains DRAM, as WB. Making it generally not necessary to allocate MTRRs for memory above 4G if no PCI BARs are placed up there.

2022-02-05cpu/x86/lapic: Move LAPIC configuration to MP initKyösti Mälkki
Implementation for setup_lapic() did two things -- call enable_lapic() and virtual_wire_mode_init(). In PARALLEL_MP case enable_lapic() was redundant as it was already executed prior to initialize_cpu() call. For the !PARALLEL_MP case enable_lapic() is added to AP CPUs.

2021-11-03soc/amd/*/cpu: handle mp_init_with_smm failureFelix Held
When the mp_init_with_smm call returns a failure, coreboot can't just continue with the initialization and boot process due to the system being in a bad state. Ignoring the failure here would just cause the boot process failing elsewhere where it may not be obvious that the failed multi-processor initialization step was the root cause of that. I'm not 100% sure if calling do_cold_reset or calling die_with_post_code is the better option here. Calling do_cold_reset likely here would likely result in a boot-failure loop, so I call die_with_post_code here.

2021-10-22cpu/x86/mp_init: move printing of failure message into mp_init_with_smmFelix Held
Each CPU/SoC checks the return value of the mp_init_with_smm and prints the same error message if it wasn't successful, so move this check and printk to mp_init_with_smm. For this the original mp_init_with_smm function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm function is created which then calls do_mp_init_with_smm, prints the error if it didn't return CB_SUCCESS and passes the return value of do_mp_init_with_smm to its caller. Since no CPU/SoC code handles a mp_init_with_smm failure apart from printing a message, also add a comment at the mp_init_with_smm call sites that the code might want to handle a failure.

2021-10-21cpu/x86/mp_init: use cb_err as mp_init_with_smm return typeFelix Held
Using cb_err as return type clarifies the meaning of the different return values. This patch also adds the types.h include that provides the definition of the cb_err enum and checks the return value of mp_init_with_smm against the enum values instead of either checking if it's non-zero or less than zero to handle the error case.

2021-04-23soc/amd/cezanne/cpu: make sure that MAX_CPUS isn't overriddenFelix Held
Trying to limit the number of available cores by setting the MAX_CPUS Kconfig option to a lower value than the SoC's default might result in cores being enabled in the FSP-S, but not fully initialized in coreboot which will cause some malfunction. Add a static assert to make sure that this option isn't changed from the default. To limit the maximum number of cores, use the downcore_mode and disable_smt devicetree settings instead. BUG=b:184162768 TEST=Build fails if MAX_CPUS isn't the expected default.
