43dcbfd855 soc/braswell: fix ACPI table by recollecting TOLM
cherry-pick from Chromium, commit 8fbe1e7

On Braswell and Baytrail devices, by userland 'perf top',
observed demanding clocks on __vdso_clock_gettime() since
chromeos_3.18 kernel; besides, evaluated massive calling of
clock_gettime() cost, up to 700 ns in average.

It turns out that Linux kernel of map_vdso() first call of
remap_pfn_range() does not fall into reserve_pfn_range()
due to size parameter, instead it relies on lookup_memtype()
and potentially be failed to be identified as eligible RAM
resource because the function of pat_pagerange_is_ram() actually
walks through root's sibling.

Meanwhile, on current BSW (and BYT) firmware implementation
makes System RAM resources located on child leaf, combining all
of these factors makes the kernel treat the vvar page of vdso
as a uncached-minus one leading slow access in result.

This patch recollects TOLM accessing; as Aaron recalled some
core_msr_script turns off access to TOLM register, he suggests
to store tolm to avoid getting back a zero while setting acpi
nvs space.

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.)

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.

afe8aeed81 lib: put romstage_handoff implementation in own compilation unit
Instead of putting all the functions inline just put the
current implementation into a C file. That way all the implementation
innards are not exposed.

Lastly, fix up the fallout of compilation units not including the
headers they actually use.

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.

e8e118dd32 Kconfig: introduce writable boot device notion
Indicate to the build system that a platform provides support
for a writable boot device. The following will provide the
necessary support:

COMMON_CBFS_SPI_WRAPPER users
soc/intel/apollolake
soc/intel/baytrail
soc/intel/braswell
soc/intel/broadwell
soc/intel/skylake

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.
