a6381d63d5 soc/intel/skylake: Remove post SMM Relocation uCode loading
As per latest BWG, ucode reloading should be done at the end
of Mp Init, i.e., after PRMRR and other features are enabled.
No reloading specifically after SMM Relocation is required.

As, in the Common CPU MP Init code, we are already doing a
uCode load at the end of MP Init Feature Programming, hence,
the uCode loading after SMM relocation can be removed.

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.

e4d7abc0d4 lib: provide clearer devicetree semantics
The devicetree data structures have been available in more than just
ramstage and romstage. In order to provide clearer and consistent
semantics two new macros are provided:

1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST

The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.

Currently when enabling Deep S3 or Deep S5 it unconditionally gets enabled

To address this split the setting and add a separate config for Deep Sx in

All motherboards that set this config were updated, but there is no actual
change in behavior in this commit.

58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

320edbe2ba vboot: Assume EC_SOFTWARE_SYNC and VIRTUAL_DEV_SWITCH by default
The virtualized developer switch was invented five years ago and has
been used on every vboot system ever since. We shouldn't need to specify
it again and again for every new board. This patch flips the Kconfig
logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with
CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to
set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the
latter for Lumpy which seems to have been omitted incorrectly, and hide
it from menuconfig since it's a hardware parameter that shouldn't be
configurable.)

Since almost all our developer switches are virtual, it doesn't make
sense for every board to pass a non-existent or non-functional developer
mode switch in the coreboot tables, so let's get rid of that. It's also
dangerously confusing for many boards to define a get_developer_mode()
function that reads an actual pin (often from a debug header) which will
not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set.
Therefore, this patch removes all those non-functional instances of that
function. In the future, either the board has a physical dev switch and
must define it, or it doesn't and must not.

In a similar sense (and since I'm touching so many board configs
anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC.
Instead, it should just be assumed by default whenever a Chrome EC is
present in the system. This way, it can also still be overridden by
menuconfig.

7de031759b soc/intel/skylake: Add SGX initialization
This patch implements SGX initialization steps in coreboot per Intel SGX
BWG rev 2.0.8 for Kaby Lake SoC. If enabled on a Kabylake device, SoC
capability and PRM (processor reserved memory) of desired size (needs to
be configured through PrmrrSize) are provisioned for later software
stack to use SGX (i.e., run SGX enclaves).

One issue is still puzzling and needs to be addressed: by calling
configure_sgx() in cpu_core_init() which is the per-thread function, SGX
is always failing for thread 0 but is successful for other 3 threads.
I had to call configure_sgx() again from soc_init_cpus() which is the
BSP-only function to make it enable on the BSP.

Another pending work is the implementation for the Owner Epoch update
which shall be added later.

With recent change (a4b11e5c90: soc/intel/skylake: Perform CPU MP Init

resume is currently broken for all skylake/kabylake boards. All the
skylake/kabylake boards store external stage cache in TSEG, which is
relocated post MP-init. Thus, if FSP loading and initialization is
done after MP-init, then ramstage is not able to:
1. Save FSP component in external stage cache during normal boot, and
2. Load FSP component from external stage cache during resume

In order to fix this, ensure that FSP loading happens separately from
FSP initialization. Add fsp_load callback for pre_mp_init which ensures
that the required FSP component is loaded/saved from/to external stage
cache.

Currently car_stage_entry is defined only in romstage_after_verstage and
as a result when SEPARATE_VERSTAGE is not selected, there is no

The solution is move out romstage_after_verstage.S from fsp1.1 driver

build and boot issue with this change.

Besides that, rename the romstage_after_verstage to romstage_c_entry

ratio to zero. Since it is different than the non-zero value programmed
in bootblock, FSP gives reset.

To avoid the reset, set FSP UPD for CPU flex ratio override to that
value as set in bootblock.

721d1b3090 soc/intel/skylake: Fix top_of_ram calculation
FSP 2.0 implementation conditionally sets PMRR base based on
EnableC6Dram UPD. Therefore, handle the case of the PMRR base not being
set since FSP 2.0 changed behavior from FSP 1.1 implementation.

If prmrr base is non-zero value, then top_of_ram is prmrr base.

If Probeless trace is enabled, then deduct trace memory size from
calculated top_of_ram.

eedf6d8aa8 soc/intel/skylake: Disable Legacy PME for Root ports
Legacy PME are enabled by default in FSP UPD region.
When Legacy PME is enabled, then an SCI is generated and should be
handled by OS and BIOS/Coreboot in collboration. OS requires some
ACPI methods (eg _L69) which help to determine the wake source and also
to clear some registers. But this infrastructure is not present as of
now in coreboot and also linux handles PMEs natively.

Hence the SCI was never handled by OS and the status bits were never
cleared i.e., PCI_EXP_STS.

For this reason the level triggered SCI will remain active and the
system will wake up as soon as it enters S3.

To fix this, diabled Legacy PME (PmSci for Root ports).

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.

9a20551b7e soc/intel/skylake: Handle platform global reset
In FSP1.1 all the platform resets including global was handled
on its own without any intervention from coreboot.
In FSP2.0, any reset required will be notified to coreboot
and it is expected that coreboot will perform platform reset.

Hence, implement platform global reset hooks in coreboot. If Intel
ME is in non ERROR state then MEI message will able to perform
global reset else force global reset by writing 0x6 or 0xE to
0xCF9 port with PCH ETR3 register bit [20] set.

ff8bf410d9 soc/intel/skylake: Implement Global Reset MEI message
As per ME BWG, there are two mechanism to generate a Global
Reset (resets both host and Intel ME), one is through CF9h
IO write of 6h or Eh with "CF9h Global Reset" (CF9GR) bit set,
PMC PCI offset ACh[20]. Another is to issue the Global Reset
MEI message. Because any attempts to cause global reset without
synchronizing the two sides might cause unwanted side effects,
such as unwritten flash data that will get destroyed if the
host were to cause a global reset without informing Intel ME
firmware, the recommended method is to send a Global Reset MEI
message when the following conditions are met:

The PCH chipset firmware just needs to complete the Intel ME
Interface #1 initialization and check the Intel ME HFSTS state
if Intel ME is not in ERROR state and is accepting MEI commands
then firmware should be able to use Global Reset MEI message to
trigger global reset.

Furthermore, if Intel ME is in ERROR state, BIOS can use I/O 0xCF9
write of 0x06 or 0x0E command with PCH ETR3 register bit [20]
to perform the global reset.

BUG=none
BRANCH=none
TEST=Verified Global Reset MEI message is able to perform platform
global issue in ME good state.

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.

3ad63565a5 soc/intel/skylake: Correct Cache as ram size
DCACHE_RAM_SIZE_TOTAL is set to 0x40000 and is being used to
set up CAR. Whereas DCACHE_RAM_SIZE which is set to 0x10000
is used to calculate the _car_region_end in car.ld. If the FSP CAR
requirement is greater than or even close to DCACHE_RAM_SIZE then,
the CAR region for FSP will be determined to be below the overall
CAR region boundary i.e, out of CAR memory range.

This is working with FSP 1.1 because we provide the FspCarSize
and FspCarBase explicitly in a UPD. Hence, FSP is still able to
use the upper region of CAR memory for its purpose.
However, it will be a problem in case of FSP2.0 where FSP usable CAR
is calculated using _car_region_end.

So, Remove the the use of DCACHE_RAM_SIZE_TOTAL and set
DCACHE_RAM_SIZE to correct value i.e, 0x40000(256KB)

Also, as part of bootblock_pch_early_init we enable decoding
for HPET range. This is needed for FspMemoryInit to store and
retrieve a global data pointer.

And also move P2SB related definitions to a new header file.

e56191e8ec soc/intel/skylake: don't include all SPI flash drivers
The SPI host controller for the SPI boot device doesn't allow
normal probing because it uses the hardware sequencer all
the time. Therefore, it's pointless to include unnecessary
SPI flash drivers.

a7b97510ae soc/intel/skylake: Clean up SoC ASL code.
List of changes done here in this patch

1. Remove CARD definition from EMMC and SD Card Controller in scs.asl
since _RMV method does not get evaluated while setting up removable
attribute in sysfs in kernel.
"cat /sys/block/mmcblk1/removable" this command always returns 0.

This CARD Device includes _ADR which follows SDIO Bus format. But,
SD/EMMC sits on PCI Bus.
Hence this CARD Device specific _ADR code is also not needed.

2. Remove Base Address for ACPI debug output memory buffer in
systemagent.asl as it is not getting used throughout the code.
