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.

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.

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.

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.)

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.

Baytrail SoC has a bug where in some cases the DisplayPort can hang
leading to a non-working display (it just stays black). To avoid this
hang, a patch was introduced in 02/2016
(1c3b1112fa - fsp_baytrail: Fix a possible hanging DisplayPort)
but per default not switched on so that each
mainboard can decide if it wants to use this patch or not.
Recently a new case of this bug was reported by Benoit Sansoni
(benoit.sansoni@kontron.com) and he requested to enable this fix per
default as it costs him a lot of time to find the cause and even the
already available fix in coreboot. To avoid this effort for someone
else in the future we can enable this fix per default as no negative
side effects are known and it is now tested at Siemens and at
Kontron on different mainboards with success.
As the goal is to enable this code permanently the config switch is not
longer needed and is removed.

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.

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.

There are several different macros available to convert a PCI device and
function to a single 8 bit value. One is PCI_DEVFN and is defined in
device/pci_def.h. The other is DEV_FUNC and is defined in several intel
fsp based chipset implementations. In fsp_broadwell_de DEV_FUNC is even
used without being defined at all. This patch unifies the situation so
that only PCI_DEVFN is used.

i2c_init() leaves the I2C device enabled. Combined with the default
interrupt mask (0x8ff) and the fact that the interrupt line is shared,
this leads to an interrupt storm in the OS until a proper I2C driver
is loaded.
This change clears the interrupt mask to prevent the interrupt storm.

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.

The BSP and AP callback declarations both had an optional argument
that could be passed. In practice that functionality was never used
so drop it.

To include gfx.c in ramstage, there is a Kconfig option
(FSP_BAYTRAIL_GFX_INIT) which can be activated on demand.
Unfortunately, the "$"-character is missing so that this switch is
never active.

In northcluster.c, the set_resources member of struct device_operations
is set to NULL. That causes this message on the console:
PCI: 00:00.0 missing set_resources
Eliminate that warning by setting set_resources=DEVICE_NOOP.

A call to i2c_read() for a non-existent address followed by an i2c_read()
to a valid address results in a false abort status for the 2nd call.
i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT)
i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0x4000000 (I2C_ERR_ABORT)
Because the abort status register is cleared on read and wait_tx_fifo()
reads it twice, the returned status does not contain the abort status.
Fixing that changed the 2nd read to reflect the abort status.
i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT)
i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0x4000001 (I2C_ERR_ABORT)
Bit 0 indicates that the address was not acknowledged by any slave.
That's the abort status from the previous transaction.
So I added a read of the abort status before starting a transaction in
both i2c_read() and i2c_write().
i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT)
i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0 (I2C_SUCCESS)
Tested on a Bay Trail E3845 SoC.

i2c.c uses "*(volatile unsigned int *)" constructs where it could use
read32() and write32().
Switch to using read32() and write32().
