4ed8b30553 rockchip/rk3399: Adjust gpio_t format to match ARM TF
Our structure packing for Rockchip's gpio_t was chosen arbitrarily. ARM
Trusted Firmware has since become a thing and chosen a slightly
different way to represent GPIOs in a 32-bit word. Let's align our
format to them so we don't need to remember to convert the values every
time we pass them through.

aaf6322a11 rockchip/rk3399: fix DRAM gate training issue
The differential signal of DQS needs to keep low
level before gate training. RPULL will connect
4Kn from PADP to VSS and a 4Kn from PADN to
VDDQ to ensure it. But if it has PHY side ODT
connected at this time, it will change the DQS
signal level. So it needs to disable PHY side ODT
when doing gate training.

34dba35831 rk3399: Reshuffle memlayout to move PRERAM_CBMEM_CONSOLE further back
It seems that the BootROM on the RK3399 overwrites some of the earlier
parts of SRAM, including the PRERAM_CBMEM_CONSOLE area. Now that we have
a persistent CBMEM console we want that area to survive in case of an
early (pre-CBMEM) reboot, so shuffle the layout around a bit to move it
further back. (This reduces the stack size to 12KB which should still be
way more than enough.)

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.)

e91d170d21 Remove libverstage as separate library and source file class
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.

There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.

This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).

Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

7e1f68c437 rockchip/common: Loosen I2C frequency target requirements
I've recently added an assertion to ensure that the effective I2C
frequency on Rockchip SoCs is not too far off the 400KHz target due to
divisor rounding errors. A 10KHz margin worked fine for RK3399, but it
turns out that RK3288 actually only ever hit 387KHz since its I2C clocks
are based off the already pretty low 75MHz PCLKs. While we could
probably change the PCLKs to make this closer, that seems like a too
intrusive change for something that has already worked just fine for
years, so just loosen the restriction a little more instead.

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.

8e42bd1cbc rockchip/rk3399: Change PLL configuration to match Linux kernel
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).

BRANCH=gru
BUG=chrome-os-partner:59139
TEST=Booted Kevin, sanity checking display and beep. Instrumented
rockchip_rk3399_pll_set_params() in the kernel and confirmed that GPLL,
PPLL and CPLL do not get reinitialized anymore (with additional kernel
patch to ignore frac divider when it's not used). Also confirmed that
/sys/kernel/debug/clk_summary now shows pclk_pmu_src 96571429 because
the kernel doesn't even bother to reinitialize the divisor.

1f60007be8 rockchip/rk3399: Reserve enough framebuffer memory for 32bpp hires panels
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
fixed with later patches.

5ddecdcf32 rockchip/rk3399: Actually remove big CPU initialization from bootblock
CL:377541 was supposed to remove the big CPU cluster initialization from
rkclk_init() in the bootblock and move it to a more suitable place in
ramstage. Except that next to all the code cleanup I did in that patch,
I seem to have forgotten to actually remove that old code.

Big thanks to Nico for spotting that in the upstream coreboot review.

e757bf9acd rockchip/rk3399: Improve dram stability when run at high frequency
There are two modifications in the driver:
1. Correctly set speeds based on DDR frequency.
   Control the speeds in the predriver circuits to reduce power.
   SPEED[1:0]
   2'b00:less than 800Mbps(400MHz)
   2b01 : 800Mbps(400MHz) to 1600Mbps(800MHz)
   2b10 : 1600Mbsp(800MHz) to 2400Mbps(1200MHz)
   2b11 : 3200Mbps and greater
2. Configure the number of cycles for the phy clock pll wait time after
   locking, based on the DDR config file.

d3600b1405 rockchip/rk3399: Move TTB to the end of SRAM
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.
