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.

Allow the platform to override the input clock for the UART by
implementing the routine uart_platform_refclk and setting the Kconfig
value UART_OVERRIDE_REFCLK. Provide a default uart_platform_refclk
routine which is disabled when UART_OVERRIDE_REFCLK is selected. This
works around ROMCC not supporting weak routines.
Testing on Galileo:
* Edit the src/mainboard/intel/galileo/Makefile.inc file:
* Add "select ADD_FSP_PDAT_FILE"
* Add "select ADD_FSP_RAW_BIN"
* Add "select ADD_RMU_FILE"
* Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
* Place the pdat.bin files in the location specified by
CONFIG_FSP_PDAT_FILE
* Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
* Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate
UEFIPAYLOAD.fd
* Testing is successful when CorebootPayloadPkg is able to properly
initialize the serial port without using built-in values.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

BOARD_ID functionality is not what requires the GPIO lib,
but it is the mainboard specific implementations that do.
The option essentially says whether the SoC provides
<soc/gpio.h> (with the interface required by the common
GPIO code). Right now, x86 and Samsung's Exynos SOCs
don't have support for this interface.
So this should be selected by the SOC, not by
BOARD_ID_SUPPORT.

Non-x86 boards currently need to hardcode the position of their CBFS
master header in a Kconfig. This is very brittle because it is usually
put in between the bootblock and the first CBFS entry, without any
checks to guarantee that it won't overlap either of those. It is not fun
to debug random failures that move and disappear with tiny alignment
changes because someone decided to write "ORBC1112" over some part of
your data section (in a way that is not visible in the symbolized .elf
binaries, only in the final image). This patch seeks to prevent those
issues and reduce the need for manual configuration by making the image
layout a completely automated part of cbfstool.
Since automated placement of the CBFS header means we can no longer
hardcode its position into coreboot, this patch takes the existing x86
solution of placing a pointer to the header at the very end of the
CBFS-managed section of the ROM and generalizes it to all architectures.
This is now even possible with the read-only/read-write split in
ChromeOS, since coreboot knows how large that section is from the
CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be
changed on systems that place other data next to coreboot/CBFS in ROM).
Also adds a feature to cbfstool that makes the -B (bootblock file name)
argument on image creation optional, since we have recently found valid
use cases for CBFS images that are not the first boot medium of the
device (instead opened by an earlier bootloader that can already
interpret CBFS) and therefore don't really need a bootblock.

This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.
The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).

Urara CBFS header configuration is broken. CBFS header needs to be
right above the bootblock, and the CBFS data - 0x100 bytes above, to
allow room for proper CBFS wrapper structures.
Ideally only the header offset should be specified (and even that
could be derived from the bootblock size). But this is a more generic
problem to be addressed with different architectures' image layout
requirements in mind.

The Serial Peripheral Flash Interface (SPFI) block allows
communication with various devices over the SPI bus.
It uses a configurable transaction interface and it clocks
the bus according to the configured command, address, gap (aka
dummy) and data lengths.
This controller requires the SPI_ATOMIC_SEQUENCING flag set
(write and read done in the same transaction) as it cannot
directly control CS and will assert/de-assert CS at the
beginning/end of a transaction itself.
Note that the size of any transfer cannot be greater than
64KB - 1, as this is configured in a 16-bit field.
The SOC has 2 SPFI interfaces each of them providing 5 slave select
lines. SPFI 0 supports single and dual modes, SPFI 1 supports
single, dual and quad modes.
For SPFI interface 0:
- The block needs the system PLL and the following top level
SPI clock registers to be set:
- CR_cr_top_spi0clkinternal_CTRL[2:0] with division value
- CR_MIPS_CLOCK_GATE[19]: bit cr_top_SPI0CLKOUT_MIPS set
- CR_cr_top_SPI0CLKOUT_CTRL[6:0] with division value
- The following MFIO configuration parameters are also required:
Signal name Pad name MFIO mode
spim0_d0_txd MFIO_MIPS_10 0
spim0_d1_rxd MFIO_MIPS_9 0
