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.

coreboot supports three instances of sending EOP:
1. At CSE `.final' device operation
2. Early as with Alder Lake in chip_operations.init if
`SOC_INTEL_CSE_SEND_EOP_EARLY' is selected
3. At BS_PAYLOAD_BOOT as designed for Meteor Lake if
`SOC_INTEL_CSE_SEND_EOP_LATE' is selected
Currently, Alder Lake uses #3 as it results in better and more stable
boot time. However, what would deliver even better result is to not
actively wait for CSE completion.
This patch introduces a new `SOC_INTEL_CSE_SEND_EOP_ASYNC' Kconfig
which split the action of sending EOP request and receiving EOP
completion response from the CSE.
This patch used in conjunction with #1 can significantly
improves the overall boot time on a Raptor Lake design. For example
`SOC_INTEL_CSE_SEND_EOP_ASYNC' on a skolas board can deliver up to 36
ms boot time improvement as illustrated below.
| # | Late EOP | Async EOP |
|----------+----------+-----------|
| 1 | 1020.052 | 971.272 |
| 2 | 1015.911 | 971.821 |
| 3 | 1038.415 | 1021.841 |
| 4 | 1020.657 | 993.751 |
| 5 | 1065.128 | 1020.951 |
| 6 | 1037.859 | 1023.326 |
| 7 | 1042.010 | 984.412 |
|----------+----------+-----------|
| Mean | 1034.29 | 998.20 |
| Variance | 4.76 % | 5.21 % |
The improvement is not stable but comparing coreboot and FSP
performance timestamps demonstrate that the slowness is caused by a
lower memory frequency (SaGv point) at early boot which is not an
issue addressed by this patch.
We also observe some improvement on an Alder Lake design. For example,
the same configuration on a kano board can deliver up to 10 ms boot time
improvement as illustrated below.
| # | Late EOP | Async EOP |
|----------+----------+-----------|
| 0 | 1067.719 | 1050.106 |
| 1 | 1058.263 | 1056.836 |
| 2 | 1064.091 | 1056.709 |
| 3 | 1068.614 | 1055.042 |
| 4 | 1065.749 | 1056.732 |
| 5 | 1069.838 | 1057.846 |
| 6 | 1066.897 | 1053.548 |
| 7 | 1060.850 | 1051.911 |
|----------+----------+-----------|
| Mean | 1065.25 | 1054.84 |
The improvement is more limited on kano because a longer PCIe
initialization delays EOP in the Late EOP configuration which make it
faster to complete.
CSME team confirms that:
1. End-Of-Post is a blocking command in the sense that BIOS is
requested to wait for the command completion before loading the OS or
second stage bootloader.
2. The BIOS is not required to actively wait for completion of the
command and can perform other operations in the meantime as long as
they do not involve HECI commands.
On Raptor Lake, coreboot does not send any HECI command after
End-Of-Post. FSP-s code review did not reveal any HECI command being
sent as part of the `AFTER_PCI_ENUM', `READY_TO_BOOT' or
`END_OF_FIRMWARE' notifications.
If any HECI send and receive command has been sent the extra code
added in `cse_receive_eop()' should catch it.
According to commit 387ec919d9 ("soc/intel/alderlake: Select
SOC_INTEL_CSE_SEND_EOP_LATE"), FSP-silicon can sometimes (on the first
boot after flashing of a Marasov board for instance) request coreboot
to perform a global request out of AFTER_PCI_ENUM notification. Global
request relies on a HECI command. Even though, we tested that it does
not create any issue, `SOC_INTEL_CSE_SEND_EOP_ASYNC' flag should not
be associated to the `SOC_INTEL_CSE_SEND_EOP_EARLY' flag to prevent
potential a global reset command to "conflict" with the EOP command.
BUG=b:276339544
BRANCH=firmware-brya-14505.B
TEST=Tests on brya0 with and `SOC_INTEL_CSE_SEND_EOP_ASYNC' show
End-Of-Post sent soon after FSP-s and EOP message receive at
`BS_PAYLOAD_BOOT'. Verify robustness by injecting a
`GET_BOOT_STATE' HECI command with or without `heci_reset'. The
implementation always successfully completed the EOP before
moving to the payload. As expected, the boot time benefit of the
asynchronous solution was under some injection scenario
undermined by this unexpected HECI command.

On the Zen-based CPUs, P state 0 corresponds to the first P state MSR,
but on Stoneyridge this isn't the case. Introduce get_pstate_0_reg that
returns 0 for all non-CAR AMD CPUs.

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.
Now that the code is using get_pstate_core_freq, this code is valid for
Glinda too, so also remove the comment on the
SOC_AMD_COMMON_BLOCK_TSC_FAM17H_19H option being selected in the Glinda
Kconfig. This Kconfig option will be renamed in a follow-up patch.

Factor out the get_pstate_core_freq function from the SoC's acpi.c files
to both avoid duplication and to also be able to use the same function
in the TSC frequency calculation in a follow-up patch. The family 17h
and 19h SoCs use the same frequency encoding in the P state MSRs while
the family 1Ah SoCs use a different encoding. The family 15h and 16h
SoCs use another encoding, but since this isn't implemented in
Stoneyridge's acpi.c, this will be added in a follow-up patch.
