Since the 16MByte of memory-mapped SPI flash region right below the 4GB boundary is both a fixed region and isn't decoded on a device below the LPC device, but assumed to be decoded by the LPC device itself, it shouldn't be reported as a subtractive resource, but as an MMIO resource instead.

2023-03-31soc/amd/common/cpu: use TSC_MONOTONIC_TIMER for SOC_AMD_COMMON_BLOCK_TSCFelix Held
All AMD SoCs with Zen-based CPU cores are already using timestamps based on the TSC counter, so use the existing common infrastructure instead of reimplementing it in a similar way. The behavior of the code changes slightly, but results in identical timestamps. The timestamp_get implementation in soc/amd/common/block/cpu divided the result of rdtscll() in timestamp_get by the result of tsc_freq_mhz() and didn't override the weak timestamp_tick_freq_mhz implementation that returns 1. The non AMD specific code returns the result of rdtscll() in timestamp_get, but returns tsc_freq_mhz() instead of 1 in timestamp_tick_freq_mhz, so we still get the correct timestamps. TEST=The raw timestamps printed on the serial console are now multiplied by the expected factor of the TSC frequency in MHz. TEST=Normalized timestamps printed on the serial console by the x86 code don't change significantly on Mandolin when comparing before and after this patch. A slight variation in the timestamps is expected. An example would be: Before: CPU_CLUSTER: 0 init finished in 630 msecs After: CPU_CLUSTER: 0 init finished in 629 msecs TEST=The calculations of the time spent in verstage on PSP before entering the bootblock on Guybrush result in similar times when multiplying the value before the patch with the TSC frequency in the case with the patch applied. The raw values printed on the serial console by the verstage on PSP use the 1us time base, but the timestamp logs that end up in CBMEM will be fixed up to use the same time base as the x86 part of coreboot.

2023-03-29soc/amd/stoneyridge/acpi: add C state config tableFelix Held
The C state ACPI packages binaryPI generates and passes to coreboot in the PSTATE SSDT only include the C2 state, but the kernel will add the C1 state to its usable C states in this case. The native C state code will generate both the C1 and C2 state packages to be more complete and also to be more in line with the other AMD SoCs. The code added in this commit isn't used yet, but will be used as soon as Stoneyridge will be using the common AMD generate_cpu_entries by selecting SOC_AMD_COMMON_BLOCK_ACPI_CPU_POWER_STATE once all needed helper functions are implemented for Stoneyridge.

Use get_pstate_core_freq instead of open-coding the calculations in tsc_freq_mhz. In the case of the CPU frequency divider being 0, get_pstate_core_freq will return 0; in this case that shouldn't happen, TSC_DEFAULT_FREQ_MHZ will be used as frequency, since for the TSC frequency it's better to err on the end of the expected frequency being too high which will cause longer than expected delays instead of too short delays.

2023-03-20soc/amd/mendocino: introduce and use pstate_msr bitfield structFelix Held
Add the pstate_msr union of a bitfield struct and a raw uint64_t to allow easier access of the bitfields of the P state MSRs and use this bitfield struct in get_pstate_core_freq and get_pstate_core_power. The signature of those two function will be changed in a follow-up commit.
