8c72670ba5 AMD Fam14 DSDT: Remove INI method from AZHD device
I am removing the _INI method from the AZHD device because
it does not seem to do anything and causes errors in the
FWTS[1] (Firmware Test Suite) test 'method'. The INI
method performs device specific initialization and is
run when OSPM loads a description table.  It must only
access OperationRegions that have been indicated as
available by the _REG (Region) method.  We do not have a
_REG method and during my testing, I added a REG method
but it did not seem to make a difference in the PCI
register space.  The bit fields defined as NSDI (Disable
No Snoop), NSDO (Disable No Snoop Override), and NSEN
(Enable No Snoop Request) do not ever get written from
their default values.  And writing to these bit fields
does not seem to be necessary because I did not notice
any change in audio functionality.

In an effort to clean up as many FWTS errors as possible,
I propose removing this method altogether.  I have seen no
change in operation (audio works with and without this
method) and there does not seem to be any change in lspci
or dmesg.

FWTS information can be found here:

00a0e76bc5 AMD Fam14 DSDT: Add OSC method
The _OSC method is used to tell the OS what capabilities
it can take control over from the firmware.  This method
is described in chapter 6.2.9 of the ACPI spec v3.0.
The method takes 4 inputs (UUID, Rev ID, Input Count,
and Capabilities Buffer) and returns a Capabilites
Buffer the same size as the input Buffer.  This Buffer
is generally 3 Dwords long consisting of an Errors
Dword, a Supported Capabilities Dword, and a Control
Dword.  The OS will request control of certain
capabilities and the firmware must grant or deny control
of those features.  We do not want to have control over
anything so let the OS control as much as it can.

The _OSC method is required for PCIe devices and dmesg
checks for its existence and issues an error if it is
not found.

26855fc70b AMD Fam14 DSDT: Add secondary bus range to PCI0
Adding the 'WordBusNumber' macro to the PCI0
CRES ResourceTemplate in the Persimmon DSDT.
This sets up the bus number for the PCI0 device
and the secondary bus number in the CRS method.
This change came in response to a 'dmesg' error
which states:
'[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS'

By adding the 'WordBusNumber' macro, ACPI can set
up a valid range for the PCIe downstream busses,
thereby relieving the Linux kernel from "guessing"
the valid range based off _BBN or assuming [0-0xFF].
The Linux kernel code that checks this bus range is
in `drivers/acpi/pci_root.c`.  PCI busses can have
up to 256 secondary busses connected to them via
a PCI-PCI bridge.  However, these busses do not
have to be sequentially numbered, so leaving out a
section of the range (eg. allowing [0-0x7F]) will
unnecessarily restrict the downstream busses.

4fc600442b AMD Fam14 boards: Set P_BLK length to 6 for all processors
Currently on for example on AMD Persimmon and ASRock E350M1 Linux
complains, that the PBLK length is invalid [1].

        ACPI: Invalid PBLK length [0]

Consequently, frequency scaling might not work correctly, though for
these two boards it seems to work according to PowerTOP.

Indeed, according to the ACPI specification [2], setting PBlockLength
to 0 is only allowed if there is no PBlockAddress. Otherwise it has to
be set to 6.

        18.5.93 Processor (Declare Processor)

        […]

        PBlockAddress provides the system I/O address for the processors
        register block. Each processor can supply a different such
        address. PBlockLength is the length of the processor register
        block, in bytes and is either 0 (for no P_BLK) or 6. With one
        exception, all processors are required to have the same
        PBlockLength. The exception is that the boot processor can have
        a non-zero PBlockLength when all other processors have a zero
        PBlockLength. It is valid for every processor to have a
        PBlockLength of 0.

And that is exactly what Linux is checking in
`drivers/acpi/processor_driver.c` [3].

        static int acpi_processor_get_info(struct acpi_device *device)
        {
        […]
                /*
                 * On some boxes several processors use the same processor bus id.
                 * But they are located in different scope. For example:
                 * \_SB.SCK0.CPU0
                 * \_SB.SCK1.CPU0
                 * Rename the processor device bus id. And the new bus id will be

                 * CPU+CPU ID.

                        ACPI_DEBUG_PRINT((ACPI_DB_INFO, "No PBLK (NULL address)\n"));
                else if (object.processor.pblk_length != 6)

                }
        […]
        }

This issue has proliferated to all AMD based boards so fix it for
all of them by setting P_BLK length to 6.

The DSDT of for example AMD Parmer and AMD Thatcher also set it
to 6 everywhere so this solution is taken instead of setting the
P_BLK system I/O base to 0 for all but the first processor which
is how it is done for earlier AMD based boards.

As note having to set this manually should not be needed and
this should be autogenerated as done for most of the Intel boards
and the AMD K8 based boards (`src/cpu/amd/model_fxx/powernow_acpi.c`).

12d60247ab AMD boards: ACPI DSDT: Use COREBOOT for the OEM Table ID field
The DSDT header contains the fields OEMID and OEM Table ID. See
for example ACPI specification 4.0a [1]

    5.2.11.1 Differentiated System Description Table (DSDT)

on page 135. There Table 5-16 contains the descriptions.

Field         Byte Length  Byte Offset  Description
===================================================
OEMID         6            10           OEM ID
OEM Table ID  8            16           The manufacture model ID.

Currently in coreboot there is no common method what to put in
these fields.

Mostly Intel based boards populate it with "CORE  " ore "COREv4"
and AMD based boards populate it with the board vendor and
model number, abbreviated appropriately to fit into these fields.

On most boards the proprietary vendor BIOS seems to leave these
fields – displayed with `sudo dmidecode` under System Information –
blank

    To Be Filled By O.E.M.

and fill out the Base Board Information with the board vendor and
model name.

In [2] Jens Rottmann argues that the this is really just the table
ID used for naming it and that »99% of the DSDT code is not board
specific«.

Both approaches seem to have their advantages, but using the
second one, developers often seem to forget to update them (for
example AMD Thather).

The current situation is at least not optimal. and therefore at
least unify the string in the OEM Table ID. If unifying the
OEM ID is also a good idea this should be done too.

If later on it should be decided that the board vendor and model
should be used again, this should be somehow derived from
Kconfig.

The following command was used for the change [3].

    $ git grep -l '\/\* TABLE ID \*\/' | xargs sed -i '/TABLE ID/s/"\([^"]*\)"/"COREBOOT"/'

This patch is split out from [2].

The name of processor created by AGESA is P00n, whose P is
BLDCFG_PROCESSOR_SCOPE_NAME(is 'C' if it is undefined.) and n starts
from 0. The dsdt should be aligned with that.
This feature has only been tested on persimmon. The changes on all the
other boards were propagated.
