Jens Rottmann 5e70766f14 AMD Fam14 boards: reduce unnecessary differences, 2nd attempt
This patch reduces unnecessary differences between AMD Inagua, Persimmon,
Union Station, South Station and Asrock E350M1. It's only cosmetical, but
makes them a little bit easier to compare.

This is the remainder of the original http://review.coreboot.org/2464,
parts of which somehow got lost in a flurry of refactoring and splitting
patches.

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.

Gabe Black b4523bb691 libpayload: Change the measurement interval for get_cpu_speed to 2 ms.
The interval used to be about 55 ms which is excessively long. Coreboot only
waits for 2 ms and gets a reasonable answer. That should be good enough for us
as well.

Dave Frodin 502533f656 Revert "AMD S3: Program the flash in a bigger data packet"
This reverts commit ca6e1f6c04.
The packet size changes ends up corrupting the flash when booting
Persimmon. I did figure out that the maximum number of bytes that
can be sent is actually 8 bytes according to the sb800 spec. There
must be additional problems beyond that since setting the packet
size to 8 still causes problems.

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)
        {

                }
        […]
        }

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`).

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].

Thanks to the awesome help of gnomon and BlastHardcheese in the

following command to do the actual work.

    $ cd src/mainboard
    $ for f in */*/mainboard.c ; \

`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!

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_
    […]

Mike Loptien ac529b1e15 AMD/Persimmon: Add RTC init to CIMX SB800
Adding RTC init code to the Southbridge initialization
code in 'late.c'.  This initializes the RTC so that the
Date Alarm register is set to a valid value (0x00) at
startup.  By setting the Date Alarm register to 0x00,
it does not get evaluated along with the seconds,
minutes, and hours when running 'fwts s3'.
Information about fwts (Firmware Test Suite) can be
found here:
https://wiki.ubuntu.com/Kernel/Reference/fwts

This was tested on a Persimmon but will apply to
other mainboards as well.

For x86, the old CBFS search behavior was to bypass bootblock and we should keep
that.  This will speed up searching if a file does not exist in CBFS.
For arm, the size in header is correct now so we can remove the hack by
CONFIG_ROM_SIZE.

Ronald G. Minnich 601b27596f ARMV7: minor tweaks to inter-stage calling and payload handling.
Payloads, by design, can return. There's lots of mechanism in the payload code
to support it, and the chooser payload relies on it. Hence, we should not mark
the function call in exit_stage as noreturn.

Not all ARM have unified caches, and it's not always easy to tell what
to do. So we are very paranoid. Before we call between stages, we
should carefully flush the dcache to memory and invalidate the icache.
This may be more than is necessary on all architectures but it
doesn't really hurt for the most part.

So compile cache management code into all stages, and call the
flush dcache/invalidate icache from all stages.

    	sb_config->AzaliaSdin0 = AZALIA_SDIN_PIN;

The 8 bit value 0x2A (binary 00 10 10 10), was being used incorrectly
– I believe the original intent of this value was to enable the SDIN
pins 0, 1, & 2. Because it was getting truncated as it was put into
AzaliaSdin0, this wasn't happening and only SDIN0 was being enabled.

I am leaving only SDIN0 enabled at this point to as not change the
actual behavior on the platform.

David Hendricks fdcef1ace9 move uartmem_getbaseaddr() to generic uart header
This moves uartmem_getbaseaddr() from an 8250-specific header to the
generic uart header. This is to accomodate non-8250 memory-mapped
UARTs.

David Hendricks 249cdc3943 snow: add cpu_cluster and domain resources via devicetree.cb
This patch will cause the resource allocator to actually set aside
the memory resources using methods in the previous patch. The coreboot
table output will include "RAM" entries (there were none before):

coreboot memory table:
 0. 0000000040400000-00000000bff001ff: RAM
 1. 00000000bff00200-00000000bff00fff: CONFIGURATION TABLES
 2. 00000000bff01000-00000000bfffffff: RAM

Patrick Georgi 11a7db3b57 romcc: Don't fail on function prototypes
Instead, ignore them. One is as non-standard as the other
and ignoring is more convenient since we don't need to
guard prototypes with #ifndef __ROMCC_ all the time.
