deed5fbebd fsp_baytrail: Enable graphic init per default
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.

4fb64d0b88 fsp 1.0 systems: Check for NULL when saving HobListPtr
Die if cbmem_add can't allocate memory for the hob pointer.  This
shouldn't ever happen, but it's a reasonable check.

- fsp_broadwell_de already had a check, but it returned to someplace
inside the FSP.  Just die instead.

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.

1. Define a new structure spi_ctrlr that allows platforms to define
callbacks for spi operations (claim bus, release bus, transfer).
2. Add a new member (pointer to spi_ctrlr structure) in spi_slave

3. Define spi_claim_bus, spi_release_bus and spi_xfer in spi-generic.c
which will make appropriate calls to ctrlr functions.

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.

bd366ab485 fsp_baytrail: Refactor code for SPI debug messages
Use the config switch CONFIG_DEBUG_SPI_FLASH on compiler level rather
then on preprocessor level to ensure that the code is compiled even if
the switch is not selected. In addition the following two changes are
introduced:

1. Prepend the debug messages with 'SPI:' to make the output more
   meaningful.
2. Change the address mask from 0xffff to 0x3ff and remove the subtraction
   of the constant value 0xf020 in order to print only the register
   offset within the SPI controller and avoid the visibility of any
   fragments from SPI base address.
3. Switch to uint8_t and friends instead of u8 to sync up with other
   code in the same file.

77e351d9d1 intel/fsp_baytrail: Fix I2C abort logic
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.

5aecd0e533 intel/fsp_baytrail: Use read32() and write32() in i2c.c
i2c.c uses "*(volatile unsigned int *)" constructs where it could use
read32() and write32().
Switch to using read32() and write32().

The remaining instances in wait_tx_fifo() and wait_rx_fifo() are fixed
in https://review.coreboot.org/#/c/14160/

08bfba4f02 intel/fsp_baytrail: Enable LPSS in ACPI mode
This change fixes LPSS ACPI mode. Previously, enabling ACPI mode would
result in unusable devices, as the resources were set to 0 and the devices
were disabled.
lpss.c was copied from intel/baytrail with a few minor adjustment for the
different config structure.

ACPI mode requires setting PcdLpssSioEnablePciMode==LPSS_PCI_MODE_DISABLE
and applying the patch that disables clearing gnvs.
https://review.coreboot.org/#/c/14040/

This doesn't handle the case where the FSP has PcdLpssSioEnablePciMode
set to disable and the devicetree set to default.

1c3b1112fa fsp_baytrail: Fix a possible hanging DisplayPort
On some devices it can happen that DisplayPort TX lanes
do not work properly if the power gate setup is omitted.
If that happens, DisplayPort training will fail and therefore
DisplayPort channel will not work. Both ports are affected.
It seems that not every CPU shows this effect
and those that are affected tend to fail more often in a cold
environment.
With this fix a board that originally shows this failure
was running for over 1000 power cycles without issues.

b95a074586 fsp_baytrail: Add additional PCI space above 4GB
This just tells the OS that it can use the 16GB of address space
at the 48GB mark for PCI.  This is the upper 16GB of Bay Trail's 36 bit
physical address space.

This could be hardcoded into the UMEM definition, but doing it this way
makes it more plain what it's doing, and allows for modification
to put it just above the top of upper memory, similar to what is done
with the standard PCI region above the top of low memory.

49bbfcd5d3 intel/fsp_baytrail: Fix PCI_DEV_PIRQ_ROUTE macro ending
The macro PCI_DEV_PIRQ_ROUTE ends with a comma and escaped newline.
Ending a macro with an escaped newline is always wrong.
The final comma is not necessary, as all uses of PCI_DEV_PIRQ_ROUTE()
properly separate calls with a comma.

I haven't investigated whether this is causing a real issue, but it should
be leaving gaps in struct baytrail_irq_route.pcidev.

The non-FSP baytrail does not have this issue.
