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.

Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.
Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
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.

The kernel ACPI was not happy with the Add inside a
ResourceTemplate (or perhaps within the IO declaration)
Instead make a buffer of IO reservations and turn _CRS
into a method that updates the buffer depending on the
chipset type.
This adds an \ISLP() method that checks the chipset LPC
device ID to see if it is -LP or -H.
It also increases the PM base reservation to 256 bytes
and moves both GPIO and PM base to above 0x1000 on -LP
chipsets.

There are subtle yet significant differences in some of the
registers in the power management region between LynxPoint-H
and LynxPoint-LP.
In order to reduce code that is accessing these registers and
would need special cases this adds a number of helper functions
that can be used in both ramstage and SMM.
This commit just adds the new functions, subsequent commits will
start to use them.

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
-------- --------
90:3,859,310 (473) 90:3,863,647 (454)
99:3,989,578 (130,268) 99:3,888,709 (25,062)

99:3,964,535 (129,934) 99:3,920,213 (29,649)
Booted baskingridge many times and observed 100ms reduction in

We had done this in TOT for current platforms but did not
carry it back to emeraldlake2 where this branched from.
If we clear the status here then we don't get an event
logged later which can be important for the devices that
do not have a CMOS battery.

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.

However, the _size variant is an absoult symbol. If one wants to
relocate the smi loading the _size symbol will be relocated which is
wrong since it is suppose to be a fixed size. There is no way to
distinguish symbols that shouldn't be relocated vs ones that can.
Instead use the _start and _end variants to determine the size.

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.

It is also very pedantic about its operation so it

The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore,
the southbridge support is included as well. The basis for this code is
the Sandybridge code. Management Engine, IRQ routing, and ACPI still requires
more attention, but this is a good starting point.
This code partially gets up through the romstage just before training
memory on a Haswell reference board.

from 0x8000. Update the em64t101_smm_state_save_area_t

Note: I have no idea what eptp is. It's just listed in the

These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.
With ramstage.a gone, we can drop this special class, too.

- Fix use of CONFIG_SPI_FLASH_NO_FAST_READ in SPI drivers

- Relocate flash functions in SMM so they are usable.
This really only needs to happen for read function pointer

Our driver infrastructure became more flexible recently.
Make use of it.
These are the low hanging fruits (files with 5 device
variants or more), but there are still lots of files
with less potential for deduplication.

This will allow various teams to select which thermal sensor
will control the thermal zones.
Also add a method to notify the thermalzones of a change
so these threshold/sensor methods take effect.
Needs a modified BIOS that uses the NVS TMPS value in
the thermalzone to read a different sensor.
Then, use a kernel driver that contains the following:
/* Adjust temperature sensor id to 2 */
union acpi_object param;
struct acpi_object_list input;
param.type = ACPI_TYPE_INTEGER
param.integer.value = 2
input.count = 1;
input.pointer = ¶m;
acpi_evaluate_object(NULL, "\\TMPU", &input, NULL);
And ensure that the temperature sensor that is being
monitored switches to ID 2.

The ME device was being sent EOP and the PCI device hidden during
coreboot so it was not available in the SMI finalize step.
This also flips the PCI vendor/device dword around for the match.

that ME EOP message is sent and the device is hidden at end of

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.

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.

There are enough differences that it is worth defining the
proper map for the sandybridge/ivybridge CPUs. The state
save map was not being addressed properly for TSEG and
needs to use the right offset instead of pointing in ASEG.
To do this properly add a required southbridge export to
return the TSEG base and use that where appropriate.

- change mdelay(1) to udelay(500) since mdelay is not defined

- make flash chip structure non-const so the probe function
pointers can be relocated for use in TSEG

In the short term there might be devices with Sandy Bridge CPUs
on mainboards with Panther Point PCHes. While this configuration
option is perfectly valid, coreboot currently ties Sandy Bridge to
Cougar Point and Ivy Bridge to Panther Point. One occurence is in
the ME handling code.
To make coreboot most flexible, compile both ME handlers into
coreboot and decide at runtime which one to use.
