Kyösti Mälkki ef84401149 Add directive __SIMPLE_DEVICE__
The tests for __PRE_RAM__ or __SMM__ were repeatedly used
for detection if dev->ops in the devicetree are not available
and simple device model functions need be used.

If a source file build for ramstage had __PRE_RAM__ inserted
at the beginning, the struct device would no longer match the
allocation the object had taken. This problem is fixed by
replacing such cases with explicit __SIMPLE_DEVICE__.

Add an option to mark all SPI regions write protected on each S3 resume.
We were used to lock the SPI interface in the payload which isn't run on
the resume path. So we have to do it here.

For the write protection to be effective, all write opcodes in the
opmenu have to be marked correctly (as write operations) and the whole
SPI interface has to be locked. Both is already done.

Kyösti Mälkki fb387dfb92 usbdebug: Drop duplicates of EHCI BAR relocation code
All the additional work that needs to be done in EHCI BAR relocation
is independent of the hardware platform and was functionally identical
in all the copies removed.

When USBDEBUG is not selected, PCI EHCI controllers use standard
pci_dev_read_resources() call.

With USBDEBUG selected, PCI EHCI controller's device_operations
.read_resources is replaced with pci_ehci_read_resources() call,
which in turn will replace the device_operations .set_resources call.
The replacement for .set_resources reconfigures usbdebug driver side,
and calls the original .set_resources to configure hardware side.

Nico Huber 99b024db88 bd82x6x: Fix early USB BAR programming (finally?)
The xHCI controller's MMIO space has a length of 64KiB not 4KiB.
Therefore, setting the xHCI BAR to 0xe8001000 worked the same like
setting it to 0xe8000000, as bit12 is reserved and ignored. This again
interfered with the MMIO space of the first EHCI controller and broke
S3 resume on Ivy Bridge.

AFAIK, the MRC ignores the setting of the xHCI BAR, anyway. So just drop
these lines.

a ME firmware will be included in the build.

Nico Huber a15cd66b9e sandybridge: Make build possible without descriptor.bin
On newer Intel systems, the flash ROM is shared between the host
processor (BIOS), it's Management Engine (ME) and an integrated ethernet
controller (GbE). The layout of the flash ROM (and other information) is
kept in the so called Intel Firmware Descriptor (IFD). If we only want
to build coreboot to update the BIOS section, all we need is the flash
layout.

This patch adds the option to specify the flash layout in the
mainboard's Kconfig, and thus, to build without the real IFD. However,
with such a build, one has to make sure that the IFD section on the
flash ROM won't be written over (nor any other section that hasn't been
included by coreboot). A patch to write selected sections of a flash ROM
with IFD has been sent to the flashrom mailing list [1].

earlier the CBMEM region is allocated for NVS itself during

The current cbmem region is renamed to ACPI_GNVS_PTR to
indicate that it is really a pointer to the GNVS and does
not actually contain the GNVS.

Duncan Laurie b39ba2efcf lynxpoint: Basic configuration of SerialIO devices
This adds configuration of SerialIO devices in the Lynxpoint-LP
chipset.  This includes DMA, I2C, SPI, UART, and SDIO controllers.

There is assorted magic setup necessary for the devices and
while it is similar for each device there are subtle differences
in some register settings.

These devices must be put into "ACPI Mode" in order to take
advantage of S0ix.  When in ACPI mode the allocated PCI BARs
must be passed to ACPI so it can be relayed to the OS.  When
the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS
and then updated and returned when the OS calls _CRS.

Note that is is not entirely complete yet.  We need to update
the IASL compiler in our build environment to support ACPI 5.0
in order to be able to pass the FixedDMA entries to the kernel.
There are also no ACPI methods defined yet to do D0->D3->D0
transitions for actually entering/exiting S0ix states.

This is hard to test right now because our kernel does not support
any of these devices in ACPI mode.  I was able to build and test
the upstream bleeding-edge branch of the linux-pm git tree.  With
that tree I was able to enumerate and load the driver for the
DesignWare I2C driver and attempt to probe the I2C bus -- although
there are no devices attatched.

I am also able to see the resources from ACPI in /proc/iomem get
reserved properly in the kernel.

Aaron Durbin d6d6db3717 lynxpoint: fix enable_pm1() function
The new enable_pm1() function was doing 2 things wrong:

1. It was doing a RMW of the pm1 register. This means we were
   keeping around the enables from the OS during S3 resume. This
   is bad in the face of the RTC alarm waking us up because it would
   cause an infinite stream of SMIs.
2. The register size of PM1_EN is 16-bits. However, the previous
   implementation was accessing it as a 32-bit register.

The PM1 enables should only be set to what we expect to handle in the
firmware before the OS changes to ACPI mode.

Aaron Durbin af3158c0cf lynxpoint: split clearing and enabling of smm
Previously southbridge_smm_init() was provided that did both
the clearing of the SMM state and enabling SMIs. This is
troublesome in how haswell machines bring up the APs. The BSP
enters SMM once to determine if parallel SMM relocation is possible.
If it is possible the BSP releases the APs to do SMM relocation.
Normally, after the APs complete the SMM relocation, the BSP would then
re-enter the relocation handler to relocate its own SMM space.
However, because SMIs were previously enabled it is possible for an SMI
event to occur before the APs are complete or have entered the
relocation handler. This is bad because the BSP will turn off parallel
SMM save state. Additionally, this is a problem because the relocation
handler is not written to handle regular SMIs which can cause an
SMI storm which effectively looks like a hung machine. Correct these
issues by turning on SMIs after all the SMM relocation has occurred.

Aaron Durbin fd79562915 romstage: add support for vboot firmware selection
This patch implements support for vboot firmware selection. The vboot
support is comprised of the following pieces:

1. vboot_loader.c - this file contains the entry point,
   vboot_verify_firmware(), for romstage to call in order to perform
   vboot selection. The loader sets up all the data for the wrapper
   to use.
2. vboot_wrapper.c - this file contains the implementation calling the vboot
   API. It calls VbInit() and VbSelectFirmware() with the data supplied
   by the loader.

The vboot wrapper is compiled and linked as an rmodule and placed in
cbfs as 'fallback/vboot'. It's loaded into memory and relocated just
like the way ramstage would be. After being loaded the loader calls into
wrapper. When the wrapper sees that a given piece of firmware has been
selected it parses firmware component information for a predetermined
number of components.

Vboot result information is passed to downstream users by way of the
vboot_handoff structure. This structure lives in cbmem and contains
the shared data, selected firmware, VbInitParams, and parsed firwmare
components.

During ramstage there are only 2 changes:

1. Copy the shared vboot data from vboot_handoff to the chromeos acpi
   table.
2. If a firmware selection was made in romstage the boot loader
   component is used for the payload.

Noteable Information:
- no vboot path for S3.
- assumes that all RW firmware contains a book keeping header for the
  components that comprise the signed firmware area.
- As sanity check there is a limit to the number of firmware components
  contained in a signed firmware area. That's so that an errant value
  doesn't cause the size calculation to erroneously read memory it
  shouldn't.
- RO normal path isn't supported. It's assumed that firmware will always
  load the verified RW on all boots but recovery.
- If vboot requests memory to be cleared it is assumed that the boot
  loader will take care of that by looking at the out flags in
VbInitParams.

Built and booted. Noted firmware select worked on an image with
RW firmware support. Also checked that recovery mode worked as well
by choosing the RO path.

you don't have to guard device/ includes for SMM and pre RAM

generally make the code more readable and understandable.

Potentially in the future some of the code in the io.h __PRE_RAM__

but that's another incremental change.

This makes use of the new functions from pmutil.c that take
care of the differences between -H and -LP chipsets.

It also adds support for the LynxPoint-LP GPE0 register block
and the SMI/SCI routing differences.

The FADT is updated to report the new 256 byte GPE0 block on
wtm2/wtm2 boards which is too big for the 64bit X_GPE0 address
block so that part is zeroed to prevent IASL and the kernel
from complaining about a mismatch.

This was tested on WTM2.  Unfortunately I am still unable to get an
SCI delivered from the EC but I suspect that is due to a magic
command needed to put the EC in ACPI mode.  Instead I verified that
all of the power management and GPIO registers were set to expected
values.

I also tested transitions into S3 and S5 from both the kernel and
by pressing the power button at the developer mode screen and they
all function as expected.

Aaron Durbin 94998c4d3f lynxpoint: Add cbfs_load_payload() implementation
SPI accesses can be slow depending on the setup and the access pattern.
The current SPI hardware setup to cache and prefetch. The alternative
cbfs_load_payload() function takes advantage of the caching in the CPU
because the ROM is cached as write protected as well as the SPI's
hardware's caching/prefetching implementation. The CPU will fetch
consecutive aligned cachelines which will hit the ROM as
cacheline-aligned addresses. Once the payload is mirrored into RAM the
segment loading can take place by reading RAM instead of ROM.

With the alternative cbfs_load_payload() the boot time on a baskingridge
board saves ~100ms. This savings is observed using cbmem.py after
performing warm reboots and looking at TS_SELFBOOT_JUMP (99) entries.
This is booting with a depthcharge payload whose payload file fits
within the SMM_DEFAULT_SIZE (0x10000 bytes).

Datapoints with TS_LOAD_PAYLOAD (90) & TS_SELFBOOT_JUMP (99) cbmem entries:

Baseline                          Alt
--------                          --------

Aaron Durbin 239c2e843f haswell platforms: restructure romstage main
There was a mix of setup code sprinkled across the various components:
southbridge code in the northbridge, etc. This commit reorganizes the
code so that northbridge code doesn't initialize southbridge components.
Additionally, the calling dram initialization no longer calls out to ME
code. The main() function in the mainboard calls the necessary ME
functions before and after dram initialization.

The biggest change is the addition of an early_pch_init() function
which initializes the BARs, GPIOs, and RCBA configuration. It is also
responsible for reporting back to the caller if the board is being
woken up from S3. The one sequence difference is that the RCBA config
is performed before claling the reference code.

Lastly the rcba configuration was changed to be table driven so that
different board/configurations can use the same code. It should be
possible to have board/configuration specific gpio and rcba
configuration while reusing the romstage code.

This commit updates the Lynx Point resource reservations before
the coreboot allocator assigns resources. There is no need to mark
anything as subtractive decode because there are no devices/buses
linked to the LPC device.

The I/O range reservations consists of claiming the first 4KiB
of I/O space. The PMBASE, GPIOBASE, and LPC generic I/O decode
ranges are checked against the default claimed range. If those
ranges overlap or fall outside of the default range then those
resources are added.

The MMIO range reservations consist of claiming everything from
the I/O APIC to 4GiB. The RCBA and the LPC Generic Memory range
register are then conditionally added if they fall outside of
the default MMIO range.

HPET's min ticks (minimum time between events to avoid

Via also has a special base address, so move it as well.

Apart from these (and the base address was already #defined),
the table is very uniform.

Duncan Laurie 0920915bca ELOG: Support GSMI in CPT/PPT southbridge SMI handler
In order to support the GSMI interface the SMI handler needs
to find and use the state save area from the same CPU that
initiated the SMI.  In this case it is a synchronous SMI
resulting form an IO write to port 0xB2.

To find the right CPU state save area iterate over the region
until the "IO Misc Info" field reports the expected value and
then proceed to use that state save area.

This is needed because the coreboot SMI handler only executes on
one core, and that core is non-deterministic.  It is likely that
the core executing the C SMM handler is not the same one that
actually did the IO write to 0xB2 and generated the SMI.

The GSMI parameter buffer is passed as a pointer to EBX in the
tate save area, and the GSMI command is extracted from EAX before
it is used as the return value.

This interface is tested by enabling CONFIG_GOOGLE_GSMI in the
kernel and generating events and verifying that they end up
in the event log.

Duncan Laurie 22935e1f43 CPU: Set flex ratio to nominal TDP ratio in bootblock
CPUs with configurable TDP will run the TSC at the max non-turbo
ratio for the maximum TDP value, which can cause issues if another
TDP is desired.  To deal with this we set the flex ratio to the
nominal TDP ratio early in the boot and then configure the Soft
Reset Data registers so the PCH can tell the CPU what frequency
to run at after a reset.

This is done very early in the bootblock because it is necessary
to reset the system after setting a flex ratio.

The end result is that the TSC will now increment at the max
non-turbo frequency for the nominal TDP.

On some system with 1.8GHz CPU ensure that the kernel
detects the CPU speed as ~1800mhz rather than ~2300mhz:

> dmesg | grep "MHz processor"
[    0.004000] Detected 1795.801 MHz processor.

Vadim Bendebury 3b3a1a1ee6 Provide functions to access arbitrary GPIO pins and vectors
This change adds utility functions which allow to read any GPIO pin,
as well as a vector of GPIO pin values.

As presented, these functions will be available to Sandy Bridge and
Ivy Bridge systems only.

There is no error checking: trying to read GPIO pin number which
exceeds actual number of pins will return zero, trying to read GPIO
which is not actually configured as such will return unpredictable
value.

When reading a GPIO pin vector, the pin numbers are passed in an
array, terminated by -1. For instance, to read GPIO pins 4, 2, 15 as a
three bit number GPIO4 * 4 + GPIO2 * 2 + GPIO15 * 1, one should pass
pointer to array of {4, 2, 15, -1}.

Duncan Laurie 4aca5d7e66 Fix issue with PCIe power management setup
The current early PM setup that attempts to configure dynamic clock
gating relies on PCIe functions to be enabled that may not be.
Instead of reading port 0 or 4 directly to determine the link width
use the register that refelects the soft strapping options as this
will always be available.

Also add a clear register assignment and break for port 0 in the
switch statement instead of falling through to port 4 as that could
end up setting the slot power limit based on port 4 values instead
of based on port 0.
register 0xE1=0x3f and all other root ports should have 0xE1=0x03.

When port 0 and 4 are disabled they will have 0xE1=0x3C before
being disabled by the pch enable handler.

Duncan Laurie b9fe01c881 Add an option to enable PCIe root port coalescing
Background: The PCI spec (3.0-3.2.2.3.4) requires that PCI devices
implement function 0.  The Linux Kernel therefore will not enumerate
a PCI device if it does not present a valid config space at function 0.

If a board does not have anything connected to root port 0 and it is
desired to disable the unused ports in order to save power then this
will cause the other downstream PCIe devices to go missing as they
will not be enumerated.

Intel chipsets provide a way to map root port numbers to different PCI
function numbers, thereby avoiding this issue and allowing root port 0
to be turned off.

This change adds a new chip config option 'pcie_port_coalesce' that
will collapse the enabled root ports into a linear map starting at
zero.  This option defaults to disabled as it can have a confusing
effect on the system as the declared static devicetree may not match
what is seen at runtime.  This option is also forced on if the static
devicetree disables port 0.

When each root port is processed in the early enable stage it looks
for a lower numbered root port that has been disabled and then swaps
the two assigned function numbers.

However the mapping register is write-once so it has to keep track of
the proposed mapping changes until all ports have been processed
before writing out the final map value.  At this point it also updates
the function numbers in the static device tree so they are consistent
with the new layout.

There are a few other closely related fixes in this change:

1) There is a power savings opportunity if an entire bank of ports
(0-3 or 4-7) are disabled.  This was checking the chipset revision to
look for CougarPoint B1+ stepping and that was not passing on
PantherPoint where this should always be applied.  To fix this I added
a function to determine the chipset type based on comparing the upper
byte of the device ID.

2) Apply the same chipset type check fix to the IOBP programming.

3) There is another power savings opportunity to enable dynamic clock
gating on shared PCIe resources which only applies to ports 0 and 4.
However if 0 or 4 is disabled then the later check to enable this
would fail as that device is already hidden.

Duncan Laurie c323036884 Update PCIe Root Port _PRT to handle re-mapped functions
The chipset enforces static-defined interrupt swizzling on PCIe root
ports so if a port is remapped to a different function it needs to
still report the proper interrupt map to the OS instead of assuming
that function number is equivalent to root port number.

This change also includes an update to the PCH function disable
register which was incorrect for CPT/PPT and would cause unpredictable
behavior if used.

The kernel command line was changed to add 'nomsi' in order to force
PCIe devices to use IO-APIC assigned interrupts and not MSI to ensure
that the mapping is correct.

Stefan Reinauer 816d081760 Fix SATA port map to only enable port 0
The sata controller comes up in legacy/normal mode and
is currently put into AHCI mode in romstage.

If that is removed and the controller is left alone until the
ramstage driver (like we do on Stumpy/Lumpy) then the resource
allocator will have configured the device for IDE mode with an
IO address in BAR5.  Then when the ramstage driver puts the
controller into AHCI mode it will not have the correct resources
to do the rest of the AHCI setup.

So the controller mode needs to be changed in the enable stage
rather than in the init phase.  This same register contains
the port map and it is a R/WO (write once) field so the configured
port map must be written at the same time.  For non-AHCI mode
the devicetree map was ignored before but it is used now.

Since the port map register is now written at enable step it
does not need to be written again during init.

With this change the sata port map can be reduced to just port 0
and then U-boot does not have to probe all available ports.

This might break a couple of boards on runtime, but so far, fixes were

Sven Schnelle b2f173e168 i82801gx: Fix port status in AHCI mode
The code used PCI register 0x92 to enable sata ports,
which is wrong. The ICH7 documentation states:

"This register is only used in systems that do not
support AHCI. In AHCI enabled systems, bits[3:0] must
always be set (ICH7R only) / bits[2,0] must always be set
(Mobile only), and the status of the port is controlled
through AHCI memory space."

Writing 0x0f to ICH7-M doesn't seem to hurt, so lets write
0x0f for both variants. This patch makes sata_ahci work on
my Thinkpad T60 and X60s.

Tobias Diedrich 4e22a3bc58 Add acpi_get_sleep_type() to i82371eb and P2B _PTS/_WAK methods
Build fix for src/arch/i386/boot/acpi.c if !CONFIG_SMP
Also check for acpi_slp_type 2 in acpi_is_wakeup, since S2
uses the same acpi wakeup vector as S3.
Add _PTS/_WAK methods to turn off/on the CPU/case fans and blink
the power LED while sleeping.
acpi_get_sleep_type() is in a seperate file i82371eb_wakeup.c because
it is used in both romstage and ramstage after patch 3/3, whereas
i82371eb_early_pm.c is used only in romstage.
I used the name acpi_get_sleep_type instead of  acpi_is_wakeup_early
because I think acpi_is_wakeup_early is a bit misleading as a name since it
doesn't return a boolean value.

Other chipsets so far only ever set acpi_slp_type to 0 and 3, so the
added check for acpi_slp_type == 2 (resume from S2) should not
change behaviour of other boards:

Patrick Georgi 5c0bca2ffd Inverse two arguments of cbfs-files-y and adapts its users (one of which already used the new order)
This is in reponse to feedback that the original setup was too complicated.

New cbfs-files-y behaviour:
cbfs-files-y contains the names of files as they appear in CBFS. The
arguments describe the on-filesystem name, the type and (optionally) the
position. Example:

cbfs-files-y += foo
foo-file := bar
foo-type := splashscreen
foo-position := 0xffff8000

This configures a CBFS file called "foo" that is marked "splashscreen",
located at 0xffff8000 in flash and contains the data of the file "bar"
in the filesystem (either in the current directory, ie. where the
corresponding Makefile.inc resides, or if that doesn't exist, relative
to the toplevel directory).

Here is a solution using the SSDT.

Unfortunately iasl does not resolve simple arithmetic at compile
time, so we can not use Add(DEFAULT_PMBASE, PCNTRL) in the
Processor statement.
This patch instead dynamically generates the processor statement.
I can't use the speedstep generate_cpu_entries() directly since the
cpu doesn't support speedstep.
For now the code is in the southbridge directory, but maybe it
should go into cpu/intel/ somewhere.
IIRC notebook cpus of the era can already have speedstep, so it
would probably be possible to pair the i82371eb with a
speedstep-capable cpu...
Also, I don't know if multiprocessor boards (abit bp6?) would need
to be handled differently.

Abuild-tested.

stepan 836ae29ee3 first round name simplification. drop the <component>_ prefix.
the prefix was introduced in the early v2 tree many years ago
because our old build system "newconfig" could not handle two files with
the same name in different paths like /path/to/usb.c and
/another/path/to/usb.c correctly. Only one of the files would end up
being compiled into the final image.

Since Kconfig (actually since shortly before we switched to Kconfig) we
don't suffer from that problem anymore. So we could drop the sb700_
prefix from all those filenames (or, the <componentname>_ prefix in general)

- makes it easier to fork off a new chipset
- makes it easier to diff against other chipsets
- storing redundant information in filenames seems wrong

BTW, my first idea was to use an acpi method that looks up pmbase in
the pci cfg space, but when I define a method like this:

        Method(TEST, 2)
        {
                Return (Add(Arg0, Arg1))
        }

I get:
|build/mainboard/asus/p2b/dsdt.ramstage.asl     9:   Processor (CPU0,
|0x01, TEST(0xe400, 0x10), 0x06) {}
|Error    4096 -       syntax error, unexpected PARSEOP_NAMESEG,

While using the builtin Add() directly works.

Uwe Hermann 77180546c8 Add IOAPIC support for Intel 82371EB and fixup SMP on ASUS P2B-D.
- Add enable_intel_82093aa_ioapic() which enables IOAPIC usage in the
   Intel 82371EB southbridge (sets the proper chip-select) and sets an
   IOAPIC ID.

 - We only call enable_intel_82093aa_ioapic() if a board does "select IOAPIC"
   as on 82371EB-based boards the IOAPIC is an external chip (not integrated
   in the southbridge) and it's only populated on multi-CPU boards.
   That is, we cannot unconditionally enable it, only on SMP-capable boards.

 - Due to the reason explained above, remove "select IOAPIC" from
   src/southbridge/intel/i82371eb/Kconfig, and add it to
   src/mainboard/asus/p2b-d/Kconfig.

 - Also set CONFIG_MAX_PHYSICAL_CPUS to 2 on ASUS P2B-D. There are two
   CPU sockets (Slot 1) and each CPU can only have one core, multi-core CPUs
   didn't exist in that era (CONFIG_MAX_CPUS was set to 2 already).

 - Drop useless/duplicated enable_lapic() call from ASUS P2B-D's romstage.c,
   that function is always called if either CONFIG_SMP and/or CONFIG_IOAPIC
   are set.

 - Rework ASUS P2B-D mptable.c to fix a number of things:

   - Convert it to use mptable_write_buses() as all mptable.c files should do.

   - Fix incorrect IOAPICID (it's 0x11 for the external 82093AA IOAPIC).

   - Fix a bunch of hardcoded bus IDs, remove incorrect entries, etc.

This is build-tested on ASUS P2B-D, and also boot-tested successfully there.
On Linux I now get two entries in /proc/cpuinfo (where only one appeared
before this patch), i.e. both populated CPUs are found.

Thus, instead of hardcoding PCI bus:device.function numbers such as
PCI_DEV(0, 7, 0), we now simply find the ISA device via PCI IDs, which
