Patrick Georgi 1e1078d699 build system: immediately report what users are supposed to look into
Instead of just logging "Check out that file over there for this type
of values", why not emit them directly?

Raul E Rangel 9ae922abf7 cpu/x86/cpu_info.S: Remove ebx save/restore
The push/pop of %ebx was only added because smm_stub saves the canary

Raul E Rangel db3e4b943a cpu/x86/smm/smm_stub: Remove cpu_info
Now that cpu_info() is no longer used by COOP_MULTITASKING, we no
longer need to set up cpu_info in SMM. When using CPU_INFO_V2, if
something does manage to call cpu_info() while executing in SMM mode,
the %gs segment is disabled, so it will generate an exception.

Also, remnants of P_BLK support missed in CB:58096 will vanish.

(except PSS, as mentioned above).

only uCode PM Timer emulation. Add a Kconfig `NO_PM_ACPI_TIMER` denoting

This is partly redundant to `PM_ACPI_TIMER_OPTIONAL`, which will be
dropped in the follow-up change, though.

Set `EnableTcoTimer=1` in order to keep FSP from
 1) enabling ACPI Timer emulation in uCode.
 2) disabling the PM ACPI Timer.

Both actions are now done in coreboot.

`EnableTcoTimer=1` makes FSP skip these steps in any possible case
including `SkipMpInit=0`, `SkipMpInit=1`, use of the MP PPI or FSP
Multiphase Init. This way full control is left to coreboot.

Felix Held d1da9570da soc/amd/stoneyridge/include/iomap: rename I2C[ABCD]_BASE_ADDRESS defines
Picasso and Cezanne define and use APU_I2C[01234]_BASE for the base
addresses of the I2C controllers, so align Stoneyridge with this. The
ACPI device names aren't changed from I2C[ABCD] to I2C[0123] for now
since this might change behavior in the OS and would also change the
resulting binary of a timeless build.

TEST=Timeless build results in identical image for Google/Treeya.

Michael Niewöhner c47fc40022 soc/intel/pmc: add a note about legacy OSes/payloads to PM Timer Kconfig
Since ACPI 5.0A it is allowed to disable the ACPI Timer, when the
according FADT flag `ACPI_FADT_PLATFORM_CLOCK` is unset.

Starting with Skylake, most platforms (except Xeon-SP) support PM Timer
emulation, so even legacy OSes and payloads should work fine with the
hardware PM Timer disabled. However, when the `TMR_STS` functionality
is required, some legacy OSes might still not work (properly).

Add a note about this to the Kconfig help.

Michael Niewöhner 5c259642c2 soc/intel/{common,skl}: set ACPI_FADT_PLATFORM_CLOCK based on Kconfig
The FADT contains a flag `ACPI_FADT_PLATFORM_CLOCK` telling the OSPM if
a specification-compliant PM Timer is present. Currently, this flag is
set regardless of the timer being enabled or disabled.

To be specification-compliant, only set that flag, when the hardware PM
Timer is enabled. This changes behaviour of all mainboards defaulting to
USE_PM_ACPI_TIMER=n.

Note: On platforms supporting uCode PM ACPI Timer emulation, this is
      required, too, because emulation does not support `TMR_STS`. Any
      OS or software checking this flag and thus relying on the overflow
      flag would not work (properly).

Before this patch the reservation of the MMIO region of the I2C

implements this functionality as read_resources function of the I2C
device instead. This will only reserve the memory when the I2C devices
are enabled in devicetree which is a change from the previous behavior.
