The "Nominal Performance" is not the same as the "Guaranteed
Performance", but is defined as the performance a processor can deliver
continously under ideal environmental conditions.
According to edk2, this is the "Maximum Non-Turbo Ratio", which needs to
be read from MSR_PLATFORM_INFO instead of IA32_HWP_CAPABILITIES.

0x0000201000000000 - 0x0000201000400000 size 0x00400000 type 0
In this case, the base address (with 4k granularity) cannot be held in
uint32_t. This results incorrect MTRR register setup. As the consequence
UEFI forum FWTS reports following critical error:

msr_set_bit can only set single bits in MSRs and causes mixing of bit
positions and bitmasks in the MSR header files. Thus, replace the helper
by versions which can unset and set whole MSR bitmasks, just like the
"and-or"-helper, but in the way commit 64a6b6c was done (inversion done
in the helper). This helps keeping the MSR macros unified in bitmask
style.
In sum, the three helpers msr_set, msr_unset and msr_unset_and_set get
added.
The few uses of msr_set_bit have been replaced by the new version, while
the used macros have been converted accordingly.

The shld instruction does an arithmetic shift left on 64bit operants,
but it's not the instruction we want, because what it actually does is
shifting by cl, and storing the result in address 32.
This wasn't noticed with QEMU as the DRAM is up and address 32 is valid.
On real hardware when CAR is running this instruction causes a crash.
Replace the instruction with the correct 64bit arithmetic left shift.

Current implementation uses CPUID 0Bh function that returns the number
of logical cores of requested level. The problem with this approach is
that this value doesn't change when HyperThreading is disabled (it's in
the Intel docs), so it breaks generate_cpu_entries().
- Use MSR 0x35 instead, which returns the correct number of logical
processors with and without HT.
- Rename the function to get_logical_cores_per_package, which is more
accurate.
Tested on ThinkPad X220 with and without HT.

This is required for Super I/Os to be able to read the CPU temperature
through PECI.
On 45nm Core 2 CPUs (Wolfdale, Yorkfield) it is not enabled by default.
This is probably related to erratum AW67 "Enabling PECI via the PECI_CTL
MSR incorrectly writes CPUID_FEATURE_MASK1 MSR". The suggested
workaround is "Do not initialize PECI before processor update is
loaded". Since coreboot performs microcode updates before running this
code it should not cause any trouble. It was tested on a Core 2 Duo
E8400, stepping E0.
PECI is already enabled by default on older (65nm) CPUs. Tested: Pentium
Dual-Core E2160.
See commit edac28ce65e48d6b2a0a2421d046a4fe4b2bf589 for the same change
on cpu/intel/model_6fx.

Fix an issue the assembler didn't warn about to fix a crash on real
hardware. qemu didn't catch this issue either.
The linker uses the same address for variables in BSS if they aren't
initialized in the code. This results in %edx being set to the value
of %eax, which causes an exception restoring IA32_EFER on real
hardware.
Tested on qemu with KVM enabled.

The AM335X is a SoC, so should be in the soc tree.
This moves all the existing am335x code to soc/ and updates any
references. It also adds a soc.c file as required for the ramstage.
