This patch implements a module that can store the top_of_ram (TOM)
address into non-volatile space (CMOS) during the first boot and
use it across all consecutive boot.
As top_of_ram address is not known until FSP-M has exited, it
results into lacking of MTRR programming to cache the 16 MB TOM,
hence accessing that range during FSP-M and/or late romstage causing
long access times.
Purpose of this driver code is to cache the TOM (with a fixed size of
16MB) for all consecutive boots even before calling into the FSP.
Otherwise, this range remains un-cached until postcar boot stage
updates the MTRR programming. FSP-M and late romstage uses this
uncached TOM range for various purposes (like relocating services
between SPI mapped cached memory to DRAM based uncache memory) hence
having the ability to cache this range beforehand would help to
optimize the boot time (more than 50ms as applicable).

Even though right now TSEG will always be located below 4GB, better not
make assumptions in the SMM relocation code. Instead of clearing the
higher 32 bits and just assigning the TSEG base and per-core SMM base to
the lower 32 bits of the MSR, assign those two base addresses to the raw
64 bit MSR value to not truncate the base addresses. Since TSEG will
realistically never be larger than 4GB and it needs to be aligned to its
power-of-two size, the TSEG mask still only needs to affect the lower

also be used for the other AMD SoCs except Stoneyridge which is pre-Zen
and doesn't select SOC_AMD_COMMON_BLOCK_NONCAR. The main advantage of
using Cxxx instead of CPxx is that the Cxxx scheme supports systems with

Instead of hoping that the default the C state control IO address in
binaryPI won't interfere with any other IO space usage in coreboot,
assign the ACPI_CSTATE_CONTROL value to the CStateIoBaseAddress platform
config structure element to make sure that binaryPI will use a known
address for the IO port based C state control. binaryPI will write this
address to the MSR_CSTATE_ADDRESS and will then also use these IO ports
in the _CST packages in the PSTATE SSDT, so changing this won't cause
a mismatch between those two.
The default CStateIoBaseAddress in the FT4 Stoneyridge binaryPI used on
Careena is 0x1770, so this didn't collide with any other IO space
registers, but it's still much better to tell binaryPI which exact IO
addresses to use.
TEST=On Careena MSR_CSTATE_ADDRESS now contains the ACPI_CSTATE_CONTROL
IO base address 0x420 and the PSTATE SSDT has the IO address 0x421 in

Rework the way the C state info is generated before it gets passed to
acpigen_write_CST_package in generate_cpu_entries by separating the data
from the code. For this, the newly introduced common get_cstate_info
function is used. Separating the data from the code will eventually
allow moving generate_cpu_entries to the common AMD code.

Instead of using a magic constant in the bit_offset field of the C state
resource for the C1 state that's entered via the MWAIT instruction, use
the existing ACPI_FFIXEDHW_CLASS_MWAIT define. This value is checked by
acpi_processor_ffh_cstate_probe in the Linux kernel.

Introduce the get_cstate_info helper function that populates the caller-
provided cstate_values array with the data returned by the SoC-specific
get_cstate_config_data function. From the array get_cstate_config_data
returns, only the ctype, latency and power fields are used, so the rest
can be left uninitialized. Those 3 fields are compile-time constants.
For each entry, write_cstate_entry will generate the corresponding
resource information from the given data. In the C1 case where ctype is
1, the state is entered via a MWAIT instruction, while the higher C
states are entered by doing an IO read from a specific IO address. This
IO address is x - 1 bytes into the IO region starting at
MSR_CSTATE_ADDRESS for the Cx state. So for example C2 is entered by
reading from the C state IO base address + 1. This resource information
is generated during runtime, since the contents of MSR_CSTATE_ADDRESS
aren't necessarily known at compile-time.
MAX_CSTATE_COUNT is introduced so that the caller can allocate and pass
a buffer with space for the maximum number of C state entries. This
maximum number corresponds to the number of IO addresses the CPU traps
beginning from MSR_CSTATE_ADDRESS. In practice, it's unlikely that more
than 3 or maybe 4 C states will be available though.

Instead of having binaryPI generate a PSTATE SSDT that uses \_PR_ as the
scope for the CPU objects and patching this SSDT in coreboot to use the
\_SB_ scope in patch_ssdt_processor_scope, request binaryPI to use the
\_SB_ scope instead by setting the late platform configuration option
ProcessorScopeInSb to true.
TEST=Careena still boots and Linux doesn't show any ACPI errors with
this patch applied. With only patch_ssdt_processor_scope removed, but
the ProcessorScopeInSb option not set, Linux will complain that it can't
resolve the \PR.P00x symbols.

The legacy ACPI CPU control registers in IO space where the first 4 IO
locations control the CPU throttling value don't exist any more on the
Zen-based CPUs. Instead this IO address is written to MSR_CSTATE_ADDRESS
in set_cstate_io_addr which will cause accesses from the 8 IO addresses
beginning with ACPI_CSTATE_CONTROL to be trapped in the CPU core. Reads
from those IO addresses will cause the CPU to enter low C states.

Finally figured out why ACPI_GPE0_BLK only being 4 bytes after
ACPI_CPU_CONTROL won't work and its due to the CPU trapping 8 IO
addresses from ACPI_CPU_CONTROL on for C state control. This is set up
in set_cstate_io_addr by writing the ACPI_CPU_CONTROL value into
MSR_CSTATE_ADDRESS.

Picasso and newer don't implement the P_CNT register to control the CPU
duty cycle and also trap the C state control IO addresses directly in
the CPU, so those won't reach the FCH. This register is unused in the
Picasso code and not even defined any more in the Cezanne PPR. The
Picasso PPR does define this register, but since it's useless and might
even just be a leftover form a pre-Zen CPU generation, drop the define.
