decd062875 drivers/mrc_cache: move mrc_cache support to drivers
There's nothing intel-specific about the current mrc_cache support.
It's logic manages saving non-volatile areas into the boot media.
Therefore, expose it to the rest of the system for any and all to
use.

93bbd41ea8 soc/intel: Enable ACPI DBG2 table generation
Enable the ACPI DBG2 table generation for Intel boards.  This is
a Microsoft defined ACPI extension that allows an OS to know what
the debug port is on a system when it is not enabled by the
firmware, so it does not show up in the coreboot tables and
cannot be easily found by a payload.

broadwell: Use byte access device, set up only when enabled since
it relies on the port being put in byte access mode and using
this serial port for debug was not standard in this generation.

skylake: Enable for the configured debug port.  Skylake uses
intelblocks for UART but not ACPI.

common: Enable for the configured debug port.  This affects
apollolake and cannonlake.

Tested by compiling for apollolake/broadwell, tested by reading
the DBG2 ACPI table on kabylake board and using IASL to dump:

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.

The ASPM options (L1 substates, CLKREQ support, Common Clock and ASPM)
are hardcoded for broadwell chips, but some boards may not support
these ASPM options even if the SoC does support it (non-wired CLKREQ

This is required to disable L1 substates on the Purism/Librem 13 which
seems to have issues with NVMe drives falling into L1.2 state and not
being able to exit that state.

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.)

e392f414cd soc/intel/broadwell: Rework IGD's CDClk selection
CDClk selection was wrong in some corner cases (e.g. ULX SKUs) and,
for Broadwell, never took the devicetree config into account.

Rewrite the selection with the following in mind:

  o cpu_is_ult() might return `true` for ULX SKUs, too,

  o ULX and Broadwell-ULT SKUs can be `overclocked` with additional
    cooling, so leave that as devicetree option.

For Haswell, the following frequency selections are valid:

  o ULX: 337.5MHz by default, 450MHz optional
  o ULT: 450MHz only (maybe 337.5MHz too, documentation varies,
                      it wasn't selectable before either)
  o others: 540MHz by default, 450MHz optional

For Broadwell:

  o ULX: 450MHz by default, 337.5MHz / 540MHz optional
  o ULT: 540MHz by default, 337.5MHz / 450MHz / 675MHz optional
  o others: 667MHz by default, 337.5MHz / 450MHz / 540MHz optional

Side effects: A too high setting in the devicetree results in the
highest possible frequency now, Haswell non-ULT/ULX defaults to 540MHz
instead of 450MHz.

Fix a typo that was introduce in commit 696ebc2d (Broadwell/Sata:
Add support for setting IOBP registers for Ports 2 and 3.) [1].

Setting one of the SATA port 3 IOBP setting was using the value from

On the purism/librem13 (on which SATA port 3 is tested), this change
doesn't seem to affect anything, as that typo wasn't exhibiting any

696ebc2dbc Broadwell/Sata: Add support for setting IOBP registers for Ports 2 and 3.
The Broadwell SATA controller supports IOBP registers on ports 0 and 1 but
Browell supports up to 4 ports, so we need to support setting IOBP for
ports 2 and 3 as well.
The magic numbers (IOBP SECRT88 and DTLE) for ports 2 and 3 were only
guessed by looking at ports 0 and 1 and extrapolating from there.
Port 3 has been tested (DTLE setting on Librem 13) and confirmed to work
so we can assume that port 2 and 3 magic numbers are valid, but having
someone confirm them (through non-public documents?) would be great.

c97e042a9b lynxpoint/broadwell: fix PCH power optimizer
Setting both bits 27 and 7 of PCH register PMSYNC_CFG (PMSYNC
Configuration; offset 0x33c8) causes pre-OS display init to fail
on HSW-U/Lynxpoint and BDW-U ChromeOS devices when the VBIOS/GOP
driver is run after the register is set. A re-examination of
Intel's reference code reveals that bit 7 should be set for the
LP PCH, and bit 27 for non-LP, but not both simultaneously.

The previous workaround was to disable the entire power optimizer
section via a Kconfig option, which isn't ideal.

Test: unset bit 27 of PMSYNC_CFG and boot google/lulu,
observe functional pre-OS video output

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.
