> > err, why is it done in the bootblock? We might want to move it later.
> That's a very good question. In APL it is done 1) in early core init in bootblock AND 2) in core init in ramstage
The code in APL mentions this in cpu.c, maybe that is the reason it's also done in early init:
" Enable ACPI PM timer emulation, which also lets microcode know location of ACPI_BASE_ADDRESS. This also enables other features implemented in microcode."
Would be good to know, *what* features that are and if other platforms need this, too in early cpu init... Andrey, Furquan, Subrata: any idea?

Hello build bot (Jenkins), Nico Huber, Patrick Georgi, Martin Roth, Furquan Shaikh, Subrata Banik, Aamir Bohra, Andrey Petrov, Patrick Rudolph,

Change subject: soc/intel: deduplicate ACPI timer emulation
......................................................................
soc/intel: deduplicate ACPI timer emulation
The code for enabling ACPI timer emulation is the same for the SoCs
APL, SKL, CNL, ICL, TGL, JSL and EHL. Deduplicate it by moving it to
common code.
Note: The ACPI timer emulation can only be used by SoCs with microcode
supporting CTC (Common Timer Copy) / ACPI timer emulation.

......................................................................
include/cpu/x86: introduce new helper for (un)setting MSRs
msr_set_bit can only set single bits in MSRs and causes mixing of bit
positions and bitmasks in the MRS header files. Thus, replace the helper
by a version which can unset and set whole MSR bitmasks, just like the
"and-or"-helper, but in the way CB:42134 was done (inversion done in the
helper). This helps keeping the MSR macros unified in bitmask style.
The few uses of msr_set_bit have been replaced by the new macro, while
the used macros have been converted accordingly.
