Gabe Black ef650a5d24 libpayload: Check for completion more often in ehci_set_periodic_schedule.
This function was using mdelay in a loop to check for the completion of an USB
controller operation. Since we're busy waiting anyway, we might as well wait
only 1 us before checking again and potentially seeing the completion 999 us
earlier than we would otherwise.

The PCH register bit definition for sleep type is a little confusing.
For example, 7 is S5. To make this simpler for the mainbaord developer,
the mainboard smi sleep hander is called as mainboard_sleep(slp_typ-2).
A couple mainboard SMI handlers were using the PCH define for slp_ty,
so S3 code would be run for S5 and S5 code would never be run.

Gabe Black 37ef52d44b libpayload: Correct a constant used for scanning for USB controllers.
When checking to see if a PCI device exists at a particular bus/dev/func,
libpayload was checking the vendor and device id fields together against a 16
bit 0xffff. The two fields together are 32 bits, however, so the check was
never true, and all dev/func combinations on a particular bus would be
checked. That was slightly wasteful, but had relatively small impact.

must be additional problems beyond that since setting the packet

Paul Menzel 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)
        {
        […]
                /*

                        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`).

to devicetree.cb.  It's used on Inagua (on), but not on Persimmon (off).

Paul Menzel 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].

Ronald G. Minnich 3faa2c77ed google/snow: enable GPIO entries and CHROMEOS in building
These were not separable or it would have been two CLs.

Enable CHROMEOS configure option on snow. Write gpio support code for
the mainboard.  Right now the GPIO just returns hard-wired values for
"virtual" GPIOs.

Add a chromeos.c file for snow, needed to build.

This is tested and creates gpio table entries that our hardware can use.

Lots still missing but we can now start to fill in the blanks, since
we have enabled CHROMEOS for this board. We are getting further into
the process of actually booting a real kernel.

Paul Menzel 528640d141 mainboard.c: Name enable_dev function uniformly `mainboard_enable`
To reduce the differences between these file name the enabling
device function in the directory `src/mainboard` uniformly
`mainboard_enable` [1].

Thanks to the awesome help of gnomon and BlastHardcheese in the
IRC channel #sed on <irc.freenode.net>. gnomon came up with the
following command to do the actual work.

    $ cd src/mainboard
    $ for f in */*/mainboard.c ; \
    > do src="$(awk '/\.enable_dev = /{v=$NF; sub(/,$/,"",v); print v}' "$f")" ; \
    > [[ -z $src ]] && continue ; \
    > printf '%s\n' "g/${src}/s/${src}\([,(]\)/mainboard_enable\1/p" w | ed -s "$f" ; \
    > done

`src/mainboard/digitallogic/msm586seg/mainboard.c` and
`src/mainboard/technologic/ts5300/mainboard.c` had to be adapted
manually as no comma was used separating the struct members.

And with the following statement, gnomon is even more likable!

    My pleasure entirely.  Good luck with coreboot; I'm a big fan of the project.

Jens Rottmann 940095fe5e AMD based boards: platform_cfg.h: Replace `_*BOARDNAME*_CFG_H_` with `_PLATFORM_CFG_H_`
Reduce unnecessary differences between AMD based boards only
using the file `platform_cfg.h` for configuration making them
a little bit easier to compare.

Inagua & co. mention the board name in several places which are really not
that board specific.  Sometimes people even forget to change it:
Union Station’s platform_cfg.h starts with "#ifndef _PERSIMMON_CFG_H_".
Funny.  Change that to "_PLATFORM_CFG_H_" everywhere.

The following command was used.

    $ find . -name platform_cfg.h | xargs sed -i '/_CFG_H_/s/_.*_/_PLATFORM_CFG_H_/'

More boards seem to use that kind of naming (`git grep _CFG_H_`)
but it is not certain that this will not break anything as for
example the board AMD Dinar also has header files for
configuration stuff for the north- and southbridge.

    $ git grep _CFG_H_
    […]

Zheng Bao 22ec9f9a72 AMD S3: Introduce Kconfig variable 'S3_DATA_SIZE'
Currently the size of the volatile storage for S3 reserved in the
image is hardcoded to 32768 bytes. Make that configurable by
introducing the Kconfig 'S3_DATA_SIZE'.

As the storage space is needed for storing non-volatile, volatile and
MTRR data, add a check if the size is big enough.
