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.

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.

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.

This is a bit of a hack but it's very handy. It compiles in your static.c
and then shows what coreboot would see when it is run. It uses your static.c
and functions pulled from src/device/device_util.c.
I've already used it to debug problems with the snow device tree.
I'm waiting someone to tell me this is already written :-)

The Link native graphics commit 49428d84 [1]
Add support for Google's Chromebook Pixel
was missing some of the higher level bits, and hence could not be
used. This is not new code -- it has been working since last
August -- so the effort now is to get it into the tree and structure
it in a way compatible with upstream coreboot.
1. Add options to src/device/Kconfig to enable native graphics.
2. Export the MTRR function for setting variable MTRRs.
3. Clean up some of the comments and white space.
While I realize that the product name is Pixel, the mainboard in the
coreboot tree is called Link, and that name is what we will use
in our commits.

Currently the OS is free to use the memory located at the default
SMRAM space because it is not marked reserved in the e820. This can
lead to memory corruption on S3 resume because SMM setup doesn't save
this range before using it to relocate SMRAM.

The previous code w.r.t. resource allocation was getting lucky
based on the way fixed mmio resources on the system were being
chosen. Namely, PCIEXBAR was the lowest mmio space and the other
fixed non-standar BARs were above it. The resource allocator would
then start allocating standard BARs below that.
On top of that other resources were being added when
dev_ops->set_resources() was being called on the PCI domain. At that
point the PCI range limit were already picked for where to start
allocating from.
To ensure we no longer get lucky during resource allocation add the
fixed resources in the host bridge and add the memory controller
cacheable memory areas. With those resources added the range limit
for standard PCI BARs is chosen properly.
Depending on haswell board configurations we may need to adjust and
pass in the size of physical address space needed for PCI resources
to the reference code. For the time being the CRBs appear to be OK.
Lastly, remove the SNB workaround for reserving 2MiB at 1GiB and 512MiB.

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.

The CS5536 companion device has three different power domains.
* working domain
* standby domain
* RTC domain
When the system is "off" only the standby domain is powered.
MFGPT[7:6] are member of the standby power domain.
MFGPT7 is used to control the backlight of the device and so the
timer gets used and configured during system boot. If the system
does a reboot the timer stays configured and the Linux driver
can not use it:
"ot200-backlight: ot200-backlight.0: MFGPT 7 not availale"
The cs5535-mfgpt has a function to hard-reset all MFGPTs but the
system hangs after the first access to a MFGPT register - cause
unknown.
/*
* This is a sledgehammer that resets all MFGPT timers. This is required by
* some broken BIOSes which leave the system in an unstable state
* (TinyBIOS 0.98, for example; fixed in 0.99). It's uncertain as to
* whether or not this secret MSR can be used to release individual timers.
* Jordan tells me that he and Mitch once played w/ it, but it's unclear
* what the results of that were (and they experienced some instability).
*/
static void reset_all_timers(void)
{
uint32_t val, dummy;
/* The following undocumented bit resets the MFGPT timers */
val = 0xFF; dummy = 0;
wrmsr(MSR_MFGPT_SETUP, val, dummy);
}
After playing around with this undocumented MSR it looks like I only
need to set bit 7 to free the MFGPT7.
BTW, all MFGPT[0:5] will be reset during pll_reset().

Add support for SMM modules by leveraging the RMODULE lib. This allows
for easier dynamic SMM handler placement. The SMM module support
consists of a common stub which puts the executing CPU into protected
mode and calls into a pre-defined handler. This stub can then be used
for SMM relocation as well as the real SMM handler. For the relocation
one can call back into coreboot ramstage code to perform relocation in
C code.
The handler is essentially a copy of smihandler.c, but it drops the TSEG
differences. It also doesn't rely on the SMM revision as the cpu code
should know what processor it is supported.
Ideally the CONFIG_SMM_TSEG option could be removed once the existing
users of that option transitioned away from tseg_relocate() and
smi_get_tseg_base().
The generic SMI callbacks are now not marked as weak in the
declaration so that there aren't unlinked references. The handler
has default implementations of the generic SMI callbacks which are
marked as weak. If an external compilation module has a strong symbol
the linker will use that instead of the link one.
Additionally, the parameters to the generic callbacks are dropped as
they don't seem to be used directly. The SMM runtime can provide the
necessary support if needed.

The timekeeping code in libpayload was dependent on rdtsc, and when it was
split up by arch, that code was duplicated even though it was mostly the same.
This change factors out actually reading the count from the timer and the
speed of the timer and puts the definitions of ndelay, udelay, mdelay and
delay into generic code. Then, in x86, the timer_hz and timer_get_raw_value
functions which used to be in depthcharge were moved over to libpayload's
arch/x86/timer.c. In ARM where there isn't a single, canonical timer, those
functions are omitted with the intention that they'll be implemented by a
specific timer driver chosen elsewhere.

Change the OSC method to actually grant control of
PCIe capabilities to the OS instead of granting no
control. I believe the logic was backwards in the
original commit. Bits should be set when granting
control and cleared when not granting control. By
setting the return value to 0x00, we effectively
tell the OS that it cannot control any PCIe
capability. See section 6.2.9 of the ACPI spec
version 3.0 for more information.
This edit is a duplication of the OSC method that
is in the src/southbridge/intel/bd82x6x/pch.asl

It might be useful to provide a USB driver in the payload itself instead of in
libpayload. For example there are multiple payloads being built and linked
against the same libpayload, and they might not need or even want to have the
same set of drivers installed.
This change adds two new functions, usb_generic_create and usb_generic_remove,
which behave like the usbdisk_create and usbdisk_remove functions which are
defined for USB mass storage devices. If a USB device isn't recognized and
claimed by one of the built in USB class drivers (currently hub, hid, and msc)
and the create function is defined, then it will be called to give the payload
a chance to use the device. Once it's removed, if usb_generic_remove is
defined it will be called, effectively giving the payload notice.
Built and booted depthcharge on Link. Built depthcharge for Daisy. Built
a netbooting payload, called usb_poll() with those functions implemented, and
verified that they were called and that the devices they were told about were
reasonable and the same as what was reported by lsusb in the booted system.

EHCI controllers see transfers as a queue of transfer descriptors
(qTDs), each of which can represent an aligned area of up to 20KB. Each
qTD is processed separately, which means that a single USB packet cannot
span multiple qTDs.
While this should not be a problem according to the specification, some
USB storage devices seem to get confused when a packet in the middle of
a transfer is smaller than the maximum packet size (512 bytes) due to
falling on a qTD boundary. This patch aligns the total transfer length
per qTD to 512 bytes to avoid that problem (any excess bytes will simply
roll over to the next qTD).

Call the power_init() function. We appear to have forgotten about it
when deprecating lowlevel_init_subsystems(), but it didn't seem to
cause problems until we got to doing more interesting stuff recently.
There are some clean-ups to do from the original code, such as not
attempting to configure I2C from PMIC code, which we'll get around
to in follow-up patches.
(Credit to Gabe for spotting this)

That way when it's treated as a u32 when its value is extracted for numblocks
and blocksize below, it doesn't make the compiler unhappy, and it ensures that
the buffer will be properly aligned on architectures where that sort of thing
matters.

The current default is IDE mode which is slower compared to AHCI
mode. Therefore use AHCI mode by default.
A similar change was made for AMD Persimmon in commit
»Enable SATA AHCI for faster boot with SeaBIOS.« (96be74c7) [1]
but was indirectly reverted by »sb800: Add sata ahci/raid mode
kconfig option« (d4a0e7d0) [2].

There's a compile time error that we didn't catch since the
board defaults as used by the build bot won't expose it.
Just make watchdog_off() a no-op statement so there aren't any
stray semicolons in the preprocessor output.

The 'git describe' command is used to obtain the source tree status
information when building coreboot. As used this command expects git
tags to be defined, so it can report the discrepancy between the
current state of the tree and the latest tag.
The problem is that the coreboot source tree does not have any git
tags defined, so when 'git describe' is invoked, it reports "fatal: No
names found, cannot describe anything.". This scary message can be
seen on the console during coreboot builds.
The solution is to add --always to the `git describe' invocation,
which causes it to report the discrepancy with the latest sha1, if
any, which is better than nothing.

Despite everywhere the model name M5A88-V is used, in Kconfig the
string M5A88PM-V is used. Searching for that model string on the
WWW does not return anything which is unrelated to coreboot, so
change that string to M5A88-V.

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.
This change will apply to other AMD mainboards and
will be in a different commit.
