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.

cee8532ce3 intel/fsp_broadwell_de: Remove buggy code for SMBus clock gating
The pch_smbus_init() function contains code to enable clock gating for
the SMBus controller. Unfortunately this code is buggy and leads to a
hanging system with the latest microcode version.
The hang occurs as follows:
The clock gate register is mapped into RCBA space. After reading the
RCBA address from the LPC device config space no mask is applied to the
value (only bits 31..14 are valid while bit 0 is the enable bit). For
this reason the final address is off by one. The old microcodes at least
allowed this unaligned access to the RCBA space. With the latest
microcode this access leads to CPU hang.

Once this is fixed the next issue occurs: After setting the clock
gating bit for SMBus (bit 5) the SMBus controller disappears from the
PCI bus completely and hence no usage of it is possible anymore.

To fix this issue the clock gating code is completely removed as it was
intentionally meant to enable clock gating on the SMB_CLK line and not
the clock gating on the PCIe interface of the SMBus controller.

This issue is known already and was discussed on the mailinglist:

cacc5a3eb0 fsp_broadwell_de: Provide valid address and size for DCACHE range
On Broadwell-DE the FSP sets up DCACHE in the early call. The address
does not match the default FSP 1.0 address defined in
src/drivers/intel/fsp1_0/Kconfig which leads to errors when this range
is used in pre-ramstage stages.

This patch provides the matching DCACHE_RAM_BASE value among with a
suitable DCACHE_RAM_SIZE for the FSP based Broadwell-DE implementation.
The include order of Kconfig files makes sure that the Kconfig file in
the soc directory is sourced first and the defined values will override
the ones in src/drivers/intel/fsp1_0/Kconfig.

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.)

According to Yang York the FSP is responsible for switching the CPU into
high frequency mode (HFM). For an unknown reason this is not done for the
BSP on my platform though the APs are switched properly.
This code switches the CPU into HFM which makes sure that all cores are in
high frequency mode before payload is started.

It should not harm the operation even if FSP was successful in switching
to HFM.

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.

issue.  As the issue has been addressed in fsp1.0 driver (Change 9780),
remove the enforced workaround. Otherwise will see error message
'FSP API NotifyPhase failed' in serial log.

Verified on Intel Camelback Mountain CRB and confirmed that the serial
log error message regarding the 'FSP API NotifyPhase failed' is gone.

A copy of our uart8250io driver sneaked in with Broadwell-DE support.
The only difference is the lack of initialization (due to FSP handling
that).

mode. This switch can now be used on mainboard level to enable the
needed mode per mainboard.

b5026bf9e0 fsp_broadwell_de: Adjust printed address in SPI debug messages
For an unknown reason the printed address in the SPI debug messages is
modified before it is printed by subtracting the constant 0xf020 from
the passed in address.
What I suppose this debug code should do is to print the used register
address within the SPI controller while any parts of this address that
belongs to the SPI base address should be omitted. To fix that remove
the subtraction of 0xf020 and adjust the address mask to 0x3ff so that
only the offset to the registers inside the SPI controller will be
visible in the debug messages.
In addition switch to uint8_t and friends over u8 to sync up with used
types in this file.

62d1313925 fsp_broadwell_de: Refactor code for SPI debug messages
Currently boards based on fsp_broadwell_de fail to compile if the config
switch CONFIG_DEBUG_SPI_FLASH is selected. The error is caused by the
usage of const for the address pointer in the functions writeb_, writew_
and writel_. The reason why it stayed hidden for so long is the fact that
the switch is used with the preprocessor and nobody really selects it
until there is a bug one want to find in this area.

This patch fixes the parameter type definition which solves the error.
In addition the config switch is not used on preprocessor level anymore
but instead on compiler level. This ensures that at least the code
syntax is checked on build time even if the config option is not
selected. Also prefix the messages with "SPI:" to make them more
meaningful in a full log.

d7127b09ae fsp_Broadwell_DE: Do not set IRQ3 and IRQ4 to level
When booting Linux as a coreboot payload, serial access does not work
properly. This is because the setup code erroneously sets IRQ3 and
IRQ4 to level. The UART on Broadwell is 8250/16550 compatible, thus
ISA and edge-triggered.

This change is not necessary on the non-FSP version of Broadwell support.
The non-FSP version does not set these IRQ overrides.

Fix verified booting Linux 4.6.0-rc2 on Intel Camelback Mountain CRB,
using Intel FSP 1.0.
