15f232df08 chromeec platforms: Update ACPI thermal event handler call
Currently the thermal event handler method TEVT is defined as an extern,
then defined again in platforms with thermal event handling.  In newer
versions of IASL, this generates an error, as the method is defined in
two places.  Simply removing the extern causes the call to it to fail on
platforms where it isn't actually defined, so add a preprocessor define
where it's implemented, and only call the method on those platforms.

851dde8255 drivers/spi: reduce confusion in the API
Julius brought up confusion about the current spi api in [1]. In order
alleviate the confusion stemming from supporting x86 spi flash
controllers:

- Remove spi_xfer_two_vectors() which was fusing transactions to
  accomodate the limitations of the spi controllers themselves.
- Add spi_flash_vector_helper() for the x86 spi flash controllers to
  utilize in validating driver/controller current assumptions.
- Remove the xfer() callback in the x86 spi flash drivers which
  will trigger an error as these controllers can't support the api.

47dffa59f3 chromeec: Remove checks for EC in RO
This patch removes checks that ensure EC to be in RO for recovery
boot. We do not need these checks because when recovery is requested
automatically (as opposed to manually), we show 'broken' screen where
users can only reboot the device or request recovery manually.

If recovery is requested, Depthcharge will check whether EC is in RO
or not and recovery switch was pressed or not. If it's a legitimate
manual recovery, EC should be in RO. Thus, we can trust the recovery
button state it reports.

This patch removes all calls to google_chromeec_check_ec_image,
which is called to avoid duplicate memory training when recovery
is requested but EC is in RW.

0990fbf2d9 vboot: reset vbnv in cmos when cmos failure occurs
There's an occasional issue on machines which use CMOS for their
vbnv storage. The machine that just powers up from complete G3
would have had their RTC rail not held up. The contents of vbnv
in CMOS could pass the crc8 though the values could be bad. In
order to fix this introduce two functions:

1. vbnv_init_cmos()
2. vbnv_cmos_failed()

At the start of vboot the CMOS is queried for failure. If there
is a failure indicated then the vbnv data is restored from flash
backup or reset to known values when there is no flash backup.

5a1f9a87cb cpu/x86/mp_init: remove adjust_cpu_apic_entry()
The original purpose of adjust_cpu_apic_entry() was to set
up an APIC map. That map was effectively only used for mapping
*default* APIC id to CPU number in the SMM handler. The normal
AP startup path didn't need this mapping because it was whoever
won the race got the next cpu number. Instead of statically
calculating (and wrong) just initialize the default APIC id
map when the APs come online. Once the APs are online the SMM
handler is loaded and the mapping is utilized.

01f9aa5e54 Consolidate reset API, add generic reset_prepare mechanism
There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.

This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).

Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

de705fa1f4 drivers/spi: Re-factor spi_crop_chunk
spi_crop_chunk is a property of the SPI controller since it depends
upon the maximum transfer size that is supported by the
controller. Also, it is possible to implement this within spi-generic
layer by obtaining following parameters from the controller:

1. max_xfer_size: Maximum transfer size supported by the controller
(Size of 0 indicates invalid size, and unlimited transfer size is
indicated by UINT32_MAX.)

2. deduct_cmd_len: Whether cmd_len needs to be deducted from the
max_xfer_size to determine max data size that can be
transferred. (This is used by the amd boards.)

1210b41283 vboot: Select SoC-specific configuration for all Chrome OS boards
Some Chrome OS boards previously didn't have a hardcoded vboot
configuration (e.g. STARTS_IN_BOOTBLOCK/_ROMSTAGE, SEPARATE_VERSTAGE,
etc.) selected from their SoC and mainboard Kconfig files, and instead
relied on the Chrome OS build system to pass in those options
separately. Since there is usually only one "best" vboot configuration
for a certain board and there is often board or SoC code specifically
written with that configuration in mind (e.g. memlayout), these options
should not be adjustable in menuconfig and instead always get selected
by board and SoC Makefiles (as opposed to some external build system).

(Removing MAINBOARD_HAS_CHROMEOS from Urara because vboot support for
Pistachio/MIPS was never finished. Trying to enable even post-romstage
vboot leads to weird compiler errors that I don't want to track down
now. Let's stop pretending this board has working Chrome OS support
because it never did.)

Some variants need the internal pull resistor on GPIO_SSUS_40
set explicitly to pull down rather than disabling the pull,

c2973d196d spi: Get rid of SPI_ATOMIC_SEQUENCING
SPI_ATOMIC_SEQUENCING was added to accomodate spi flash controllers with
the ability to perform tx and rx of flash command and response at the
same time. Instead of introducing this notion at SPI flash driver layer,
clean up the interface to SPI used by flash.

Flash uses a command-response kind of communication. Thus, even though
SPI is duplex, flash command needs to be sent out on SPI bus and then
flash response should be received on the bus. Some specialized x86
flash controllers are capable of handling command and response in a
single transaction.

In order to support all the varied cases:
1. Add spi_xfer_vector that takes as input a vector of SPI operations
and calls back into SPI controller driver to process these operations.
2. In order to accomodate flash command-response model, use two vectors
while calling into spi_xfer_vector -- one with dout set to
non-NULL(command) and other with din set to non-NULL(response).
3. For specialized SPI flash controllers combine two successive vectors
if the transactions look like a command-response pair.
4. Provide helper functions for common cases like supporting only 2
vectors at a time, supporting n vectors at a time, default vector
operation to cycle through all SPI op vectors one by one.

c28984d9ea spi: Clean up SPI flash driver interface
RW flag was added to spi_slave structure to get around a requirement on
some AMD flash controllers that need to group together all spi volatile
operations (write/erase). This rw flag is not a property or attribute of
the SPI slave or controller. Thus, instead of saving it in spi_slave
structure, clean up the SPI flash driver interface. This allows
chipsets/mainboards (that require volatile operations to be grouped) to
indicate beginning and end of such grouped operations.

New user APIs are added to allow users to perform probe, read, write,
erase, volatile group begin and end operations. Callbacks defined in
spi_flash structure are expected to be used only by the SPI flash
driver. Any chipset that requires grouping of volatile operations can
select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and
define callbacks for chipset_volatile_group_{begin,end}.

spi_claim_bus/spi_release_bus calls have been removed from the SPI flash
chip drivers which end up calling do_spi_flash_cmd since it already has
required calls for claiming and releasing SPI bus before performing a
read/write operation.

The SPI_FLASH option is auto-selected if the platform provides
write supoprt for the boot device and SPI flash is the boot
device.

Other platforms may provide similar support, but they do that
in a device specific manner such as selecting SPI_FLASH
explicitly. This provides clearance against build failures
where chipsets don't provide SPI API implementations even
though the platform may use a SPI flash to boot.

6366d92803 {cpu,soc}/intel: remove unused smm_init() function
There used to be a need for an empty smm_init() function
because initialize_cpus() called it even though nothing
called initialize_cpus(). However, garbage collection at
link time is implemented so there's no reason to provide an
empty function to satisfy a symbol that is completely culled
during link. Remove it.

Instead of using CBFS_SIZE from Kconfig, use values generated from fmap.
While at it, make sure that the cached region size is a power of two.

fmap_config is also added to cpu_incs-y, but that doesn't hurt (except
for some miniscule increase in compile time) because it's #if-guarded.
The upside is that dependencies are tracked properly.

6149233cce intel/soc/baytrail: Move MCRS ResourceTemplate out of _CRS method

The ACPI compiler is trying to be helpful in letting us know
that we're not using various fields in the MCRS ResourceTemplate
when we define it inside of the _CRS method.  Since we're not
intending to use those objects in the method, it shouldn't be an
issue, but the warning is annoying and can mask real issues.
Moving the creation of the MCRS object to outside of the CRS
method and referencing it from there solves this problem.

3a54318856 Add EM100 'hyper term' spi console support in ramstage & smm
The EM100Pro allows the debug console to be sent over the SPI bus.
This is not yet working in romstage due to the use of static variables
in the SPI driver code.  It is also not working on chipsets that have
SPI write buffers of less than 10 characters due to the 9 byte
command/header length specified by the EM100 protocol.

While this currently works only with the EM100, it seems like it would
be useful on any logic analyzer with SPI debug - just filter on command
bytes of 0x11.

026e4dc3ff Kconfig: Move CBFS_SIZE into Mainboard menu
The CBFS size is really mainboard specific, since it really depends on
size of the chip on the mainboard, so it makes sense to have it in
the mainboard menu along with the ROM-chip size.

- Move the CBFS_SIZE definition up in src/kconfig
- Move the Mainboard Menu markers out of src/mainboard/kconfig into
src/Kconfig so CBFS_SIZE can live in the mainboard menu.
- Add a long list setting default values to do what the chipset
directories were previously defaulting the values to.  This will
be trimmed down in a following patch that creates a common set of
IFD routines.  (Who knew that kconfig supported line wrapping?)
- Update the help text.

4fbac46524 cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() API
Squashed and adjusted two changes from chromium.git. Covers
CBMEM init for ROMTAGE and RAMSTAGE.

cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API

There are several use cases for performing a certain task when CBMEM is
first set up (usually to migrate some data into it that was previously
kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them
differently: timestamp migration is called explicitly from
cbmem_initialize(), certain x86-chipset-specific tasks use the
CAR_MIGRATION() macro to register a hook, and the CBMEM console is
migrated through a direct call from romstage (on non-x86 and SandyBridge
boards).

This patch decouples the CAR_MIGRATION() hook mechanism from
cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer
description of what it really does. All of the above use cases are
ported to this new, consistent model, allowing us to have one less line
of boilerplate in non-CAR romstages.

cbmem: Extend hooks to ramstage, fix timestamp synching

Commit 7dd5bbd71 (cbmem: Unify random on-CBMEM-init tasks under common
CBMEM_INIT_HOOK() API) inadvertently broke ramstage timestamps since
timestamp_sync() was no longer called there. Oops.

This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism
to the cbmem_initialize() call in ramstage. The macro is split into
explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as
possible and prevent surprises (although just using a single macro and
relying on the Makefiles to link an object into all appropriate stages
would also work).

This allows us to get rid of the explicit cbmemc_reinit() in ramstage
(which I somehow accounted for in the last patch without realizing that
timestamps work exactly the same way...), and replace the older and less
flexible cbmem_arch_init() mechanism.

Also added a size assertion for the pre-RAM CBMEM console to memlayout
that could prevent a very unlikely buffer overflow I just noticed.

BRANCH=None
BUG=None

899d13d0df cbfs: new API and better program loading
A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.

All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.

The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

2eaa0d49e1 intel: Correct MMIO related ACPI table settings
Several of the intel platforms define the region reserved
for PCI memory resources in a location where it overlaps
with the MMIO (MCFG) region.

Using the memory map from mohon_peak as an example:

  0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES
  1. 0000000000001000-000000000009ffff: RAM
  2. 00000000000a0000-00000000000fffff: RESERVED
  3. 0000000000100000-000000007fbcffff: RAM
  4. 000000007fbd0000-000000007fbfffff: CONFIGURATION TABLES
  5. 000000007fc00000-000000007fdfffff: RESERVED
  6. 00000000e0000000-00000000efffffff: RESERVED
  7. 00000000fee00000-00000000fee00fff: RESERVED
  8. 0000000100000000-000000017fffffff: RAM

  The ACPI table describing the space set aside for PCI memory
  (not to be confused with the MMIO config space) is defined
  as the region from BMBOUND (the top of DRAM below 4GB) to
  a hardcoded value of 0xfebfffff. That region would overlap
  the MMIO region at 0xe0000000-0xefffffff. For rangeley
  the upper bound of the PCI memory space should be set
  to 0xe0000000 - 1.

  The MCFG regions for several of the affected chipsets are:
  rangeley    0xe0000000-0xefffffff
  baytrail    0xe0000000-0xefffffff
  haswell     0xf0000000-0xf3ffffff
  sandybridge 0xf8000000-0xfbffffff

9afc5c05f0 baytrail: Switch from ACPI mode to PCI mode for legacy support
Most Baytrail based devices MMIO registers are reported in ACPI
space and the device's PCI config space is disabled. The PCI config
space is required for many "legacy" OSs that don't have the ACPI
driver loading mechanism. Depthcharge signals the legacy boot
path via the SMI 0xCC and the coreboot SMI handler can switch the
device specific registers to re-enable PCI config space.

9ef9d85976 bootstate: use structure pointers for scheduling callbacks
The GCC 4.9.2 update showed that the boot_state_init_entry
structures were being padded and assumed to be aligned in to an
increased size. The bootstate scheduler for static entries,
boot_state_schedule_static_entries(), was then calculating the
wrong values within the array. To fix this just use a pointer to
the boot_state_init_entry structure that needs to be scheduled.

In addition to the previous issue noted above, the .bs_init
section was sitting in the read only portion of the image while
the fields within it need to be writable. Also, the
boot_state_schedule_static_entries() was using symbol comparison
to terminate a loop which in C can lead the compiler to always
evaluate the loop at least once since the language spec indicates
no 2 symbols can be the same value.

77b1655d9b vboot2: add verstage
This reverts the revert commit 5780d6f387
and fixes the build issue that cuased it to be reverted.

Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains,
compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the
boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with
verstage_.

TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

of timestamps internally stashes on CAR_GLOBAL table and migrates
those to CBMEM.

3a6550d989 timestamps: Switch from tsc_t to uint64_t
Cherry-pick from chromium and adjusted for added boards
and changed directory layout for arch/arm.

Timestamp implementation for ARMv7

Abstract the use of rdtsc() and make the timestamps
uint64_t in the generic code.

The ARM implementation uses the monotonic timer.

59e209af89 baytrail: initialize backlight PWM frequency
In order to protect ourselves from the kernel driver not honoring or
placing the correct frequency in the backlight register always set one.
This code path picks 200Hz as the default if nothing is specified in
device tree. It's somewhat arbitrary but that frequency is valid for all
the eDP panel specs we've seen being used on baytrail devices.

f2612a1061 x86: Initialize SPI controller explicitly during PCH init
This ensures that SPI is ready when eventlog code is used.

x86 platforms which use eventlog invoke elog_clear() in GSMI and
elog_add_event_raw() when deciding the boot path based on ME status.
For the SMM case spi_init() is called during the finalize stage in
SMM setup. For the boot path case we can call spi_init() at the
beginning of BS_DEV_INIT and it will be ready to use when the boot
path is determined from the ME status.
