Asserts are only fatal if CONFIG_FATAL_ASSERTS is enabled in Kconfig.
By default this is disabled, so the assert is generally just a printf.
Die if someone decides to pass in an invalid bus number for some reason.

flash_programmer_probe is a property of the spi flash driver and does
not belong in the spi_slave structure. Thus, make
spi_flash_programmer_probe a callback from the spi_flash_probe
function. Logic still remains the same as before (order matters):
1. Try spi_flash_programmer_probe without force option
2. Try generic flash probing
3. Try spi_flash_programmer_probe with force option
If none of the above steps work, fail probing. Flash controller is
expected to honor force option to decide whether to perform specialized
probing or to defer to generic probing.

max_transfer_size is a property of the SPI controller and not of the spi
slave. Also, this is used only on one SoC currently. There is no need to

This change moves the handling of max_transfer_size to SoC SPI driver

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.

The Kevin project has been too smooth and boring for our tastes in the
last last few weeks, so we've decided to stir the pot a little bit and
reshuffle all our PLL settings at the last minute. The new settings
match exactly what the Linux kernel expects on boot, so it doesn't need
to reinitialize anything and risk a glitch.
Naturally, changing PLL rates will affect child clocks, so this patch
changes vop_aclk (192MHz -> 200MHz, 400MHz in the kernel), pmu_pclk
(99MHz -> 96.57MHz) and i2c0_src (198MHz -> 338MHz, leading to an
effective I2C0 change 399193Hz -> 398584Hz).

the symbols.
- Add symbols for DDR333 - DDR667 to cygnus Kconfig. These should be
selected by the mainboard.
- Rename symbols from DDRXXX to CYGNUS_DDRXXX to match the existing
CYGNUS_DDR800 symbol.
- Rename the non Kconfig #define CONFIG_DRAM_FREQ to CYGNUS_DRAM_FREQ
because having other #defines look like Kconfig symbols is confusing.
- Change #ifdef CONFIG_DDRXXX to use IS_ENABLED

similar structures for providing settings for the i2c speed
control. Introduce a new struct lpss_i2c_bus_config and
utilize it in both apollolake and skylake thereby removing
the need for SoC-specific structres. The new structure is
used for initializing a bus fully as the lpss i2c API is
simplified in that lpss_i2c_init() is only required to be
called. The struct lpss_i2c_bus_config structure is passed
in for both initializing and filling in the SSDT information.
The formerly exposed functions are made static to reduce the

Kunimitsu platforms.
[3] Follow up patches are using DPTF_CPU_ACTIVE_AC* temperature trip
points in board specific acpi/dptf.asl (for lars, kunimitsu, etc) to
control the fan speed as per the CPU temperature trip points.
[4] Newly added _ACx methods for thermal sensor TSR0 in this patch
has nothing to do with DPTF_CPU_ACTIVE_AC*.
We can control fan speed using various different thermal sensors.
In this patch, we have added new _ACx methods for TSR0 thermal sensor.
We run the fan at different speeds to cool down the system at different
TSR0 temperatures.
Similarly, we considered CPU sensor temperature values and ran the fan
at different speeds to cool down the system.

When reading+clearing a GPE for use as an interrupt we need to
re-read the status register and keep setting the clear bit until
it actually reads back clear. Also add a 1ms timeout in case the

is still asserted when the "ISR" goes to clear the status.

1. Update write leveling value to 0x200.
When the wrdqs slave delay is changed to 0x200, the phase between the
dqs and the clock is 0 degrees. The pcb layout can make sure the tDQSS
timing is smaller than 0.25tck, so this value is useful for both higher
and lower frequencies.
2. Disable read leveling for LPDDR3.
The read leveling result is unreliable - the value is not in the middle

Some of our RK3399 devices have panel resolutions as high as 2400x1600.
With 16bpp that barely still fit into an 8MB framebuffer, but then we
changed it to 32bpp for better image quality...
Note that this is a band-aid. Coreboot-allocated framebuffers shouldn't
be used at all on ARM64 devices, since libpayload is perfectly capable
to dynamically allocate it with the right size based on EDID-information
on this architecture. That will require some more elaborate work to be

As per ME BWG, there are two mechanism to generate a Global
Reset (resets both host and Intel ME), one is through CF9h
IO write of 6h or Eh with "CF9h Global Reset" (CF9GR) bit set,
PMC PCI offset ACh[20]. Another is to issue the Global Reset
MEI message. Because any attempts to cause global reset without
synchronizing the two sides might cause unwanted side effects,
such as unwritten flash data that will get destroyed if the
host were to cause a global reset without informing Intel ME
firmware, the recommended method is to send a Global Reset MEI
message when the following conditions are met:
The PCH chipset firmware just needs to complete the Intel ME
Interface #1 initialization and check the Intel ME HFSTS state
if Intel ME is not in ERROR state and is accepting MEI commands
then firmware should be able to use Global Reset MEI message to
trigger global reset.
Furthermore, if Intel ME is in ERROR state, BIOS can use I/O 0xCF9
write of 0x06 or 0x0E command with PCH ETR3 register bit [20]
to perform the global reset.
BUG=none
BRANCH=none
TEST=Verified Global Reset MEI message is able to perform platform

We found that we may want to load some components of BL31 on the RK3399
into SRAM. As usual, these components may not overlap any coreboot
regions still in use at that time, as is already statically checked by
the check-ramstage-overlaps rule in Makefile.inc.
On RK3399, the only such regions are TTB and STACK. This patch moves the
TTB region back to the end of SRAM (right before STACK), so that a large
contiguous region of SRAM before that remains usable for BL31.

With a SPI clock above about 24MHz the APB cannot keep up when doing
individual byte transfers. Adjust the driver to use 16-bit reads when
it can, to remove this bottleneck.
Any transaction which involves writing bytes still uses 8-bit transfers,
to simplify the code. These are the transfers that are not time-critical
since they tend to be small. The case that really matters is reading from
SPI flash.
In general we can use 16-bit reads anytime we are transferring an even
number of bytes. If the code detects an odd number of bytes, it tries to
perform the operation in two steps: once in 16-bit mode with an even
number of bytes, and once in 8-bit mode for the final byte. This allow
us to use 16-bit reads even if asked to transfer (for example) 0xf423
bytes.
The limit on in_now and out_now is adjusted to 0xfffe to avoid an extra
transfer when transferring ~>=64KB.

TEST=boot on gru and see that things still work correctly. I tested (with
extra debugging) that the 16-bit case is being picked when it should be.

Some of the asserts for valid clock divisor ranges were off by one. This
patch corrects them and writes them all in a consistent way.

This patch moves the big CPU cluster initialization on the RK3399 from
the clock init bootblock function into ramstage. We're only really doing
this to put the cluster into a sane state for the OS, we're never
actually taking it out of reset ourselves... so there's no reason to do
this so early.
Also cleaned up the interface for rkclk_configure_cpu() a bit to make it
more readable.

At higher SPI bus speeds the SPI RX value is not available in time for
sampling at the normal time. Add a delay to ensure that we read the
correct data.
The value of 40ns is chosen arbitrarily. In my testing I can use a sample
delay of 1 even at 24MHz. But since it is not necessary, I have left that
case alone. It kicks in at 25MHz and up.
