55009af42c Change all clrsetbits_leXX() to clrsetbitsXX()
This patch changes all existing instances of clrsetbits_leXX() to the
new endian-independent clrsetbitsXX(), after double-checking that
they're all in SoC-specific code operating on CPU registers and not
actually trying to make an endian conversion.

This patch was created by running

 sed -i -e 's/\([cs][le][rt]bits\)_le\([136][624]\)/\1\2/g'

across the codebase and cleaning up formatting a bit.

7fc928656e lib/fmap: Disable pre-RAM cache for FSP 1.0
Due to the way CAR teardown is handled in FSP 1.0, the results of
car_get_var_ptr() aren't always reliable, which can break things when
running with FMAP cache. It might be possible to fix this but would make
the code rather complicated, so let's just disable the feature on these
platforms and hope they die out soon.

Also allow this option to be used by platforms that don't have space for
the cache and want to save a little more code.

211792feab rockchip/rk3288: Split free SRAM more evenly between stages
When CB:33068 disabled the bootblock console on RK3288, it saved a
whooping 7K of SRAM, but it didn't readjust the stage boundaries to
spread that bounty evenly. This patch moves 4K of free space from the
bootblock to verstage/romstage to allow for future expansion.

cefe89ee79 lib/fmap: Add optional pre-RAM cache
This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.

In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.

Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

RK3288 is running out of space again. I believe reducing the CBFS cache

d05f57cfcb arch/arm64: Pass cbmem_top to ramstage via calling argument
This solution is very generic and can in principle be implemented on
all arch/soc. Currently the old infrastructure to pass on information
from romstage to ramstage is left in place and will be removed in a
follow-up commit.

Nvidia Tegra will be handled in a separate patch because it has a
custom ramstage entry.

Instead trying to figure out which files can be removed from stages
and which cbmem_top implementations need with preprocessor, rename all
cbmem_top implementation to cbmem_top_romstage.

Mechanisms set in place to pass on information from rom- to ram-stage
will be replaced in a followup commit.

b3f24b4884 arm64: Uprev Arm TF and adjust to BL31 parameter changes
This patch uprevs the Arm Trusted Firmware submodule to the new upstream
master (commit 42cdeb930).

Arm Trusted Firmware unified a bunch of stuff related to BL31 handoff
parameters across platforms which involved changing a few names around.
This patch syncs coreboot back up with that. They also made header
changes that now allow us to directly include all the headers we need
(in a safer and cleaner way than before), so we can get rid of some
structure definitions that were duplicated. Since the version of entry
point info parameters we have been using has been deprecated in Trusted
Firmware, this patch switches to the new version 2 parameter format.

NOTE: This may or may not stop Cavium from booting with the current
pinned Trusted Firmware blob. Cavium maintainers are still evaluating
whether to fix that later or drop the platform entirely.

Tested on GOOGLE_KEVIN (rk3399).

4c33a3aaa3 src: Make implicit fall throughs explicit
Implicit fall throughs are a perpetual source of bugs and Coverity Scan
issues, so let's squash them once and for all. GCC can flag implicit fall
throughs using the -Wimplicit-fallthrough warning, and this should
ensure no more enter the code base. However, many fall throughs are
intentional, and we can use the following comment style to have GCC
suppress the warning.

    switch (x) {
    case 1:
            y += 1;
	    /* fall through */
    case 2:
            y += 2;
	    /* fall through - but this time with an explanation */
    default:
            y += 3;
    }

This patch adds comments for all remaining intentional fall throughs,
and tweaks some existing fall through comments to fit the syntax that
GCC expects.

eda20b677f vboot: Use CONFIG_VBOOT_MIGRATE_WORKING_DATA on all platforms
When we added CONFIG_VBOOT_MIGRATE_WORKING_DATA, the idea was that on
some Arm platforms the original working data buffer was in SRAM, which
stays accessbile for the whole runtime of the system. There is no reason
to migrate it into CBMEM on those platforms because ramstage and the
payload could continue to access it in SRAM.

Now that we've had a couple of months of experience with this option, we
found that most of our Arm platforms have some issue that requires
migrating anyway, because BL31 often claims SRAM for itself and makes it
inaccessible to the payload. On the remaining platforms, accessing SRAM
from the payload is possible but still an issue, because libpayload
doesn't have enough memory layout information to set up proper page
tables for it, so we're accessing it uncached and at risk of alignment
errors.

Rather than having to figure out how to map the right SRAM range for
every platform in the payload, let's just get rid of the option.
memcpy()ing 12KB isn't worth this much hassle.

cee06c458a rockchip/rk3399: Select VBOOT_MIGRATE_WORKING_DATA
Trusted Firmware places some components in SRAM on RK3399 and therefore
restricts accesses to SRAM to the secure world. This makes the vboot
working data inaccessible to normal world payloads, so we need to
migrate it into CBMEM.

7e0dea6317 symbols.h: Add macro to define memlayout region symbols
When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.

This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).

Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

The dependencies of CONSOLE_SERIAL and DRIVERS_UART were somehow

because it's using its interface. The individual UART drivers
select DRIVERS_UART, because they implement the interface and
depend on the common UART code.

Some guards had to be fixed (using CONSOLE_SERIAL now instead of
DRIVERS_UART). Some other guards that were only about compilation
of units were removed. We want to build test as much as possible,
right?

60828b7fa9 rk3288: Dig up two more KB of SRAM from under the couch cushions
RK3288 has always been notoriously low on SRAM, to the point where its
boards have less than 100 bytes left in both their bootblock/verstage
sections. This becomes a problem every time we try to add a tiny amount
of code to common coreboot interfaces that are included in them.

This patch manages to add another KB to each, one from the CBMEM console
(which now might get cut off a bit, but that's life) and one by moving
the TTB_SUBTABLES to PMUSRAM. PMUSRAM is a weird world where write
accesses must always be exactly 4 bytes long or they hang the CPU, so we
mostly ignore it... but thankfully, page table entries are exactly 4
bytes long and that's the only thing we write to this region, so it
works out in this case.

8f25a6680e rk3399: Enable bootblock compression
This patch enables the new bootblock compression feature on RK3399,
which requires moving MMU initialization into the decompressor stage and
linking the decompressor (rather than the bootblock) into the entry
point jumped to by the masked ROM.

RK3399's masked ROM seems to be using a bitbang SPI driver to load us
(very long pauses between clocking in each byte), with an effective data
rate of about 1Mbit. Bootblock loading time (as measured on a SPI
analyzer) is reduced by almost 100ms (about a third), while the
decompression time is trivial (under 1ms).

4783db2cf1 spi: Add helper functions for bit-banging
Sometimes when bringing up a new board it can take a while until you
have all the peripheral drivers ready. For those cases it is nice to be
able to bitbang certain protocols so that you can already get further in
the boot flow while those drivers are still being worked on. We already
have this support for I2C, but it would be nice to have something for
SPI as well, since without SPI you're not going to boot very far.

This patch adds a couple of helper functions that platforms can use to
implement bit-banging SPI with minimal effort. It also adds a proof of
concept implementation using the RK3399.

we rarely need it since gpio_output() can already be used to initialze a
GPIO to a default value while configuring it as an output. This function
was forgotten on Rockchip, so this patch adds it now.

6d643cf722 rockchip: Correct UART reference clock value
The Rockchip UARTs are tied directly to the 24MHz oscillator and are
thus clocked with exactly 24MHz. The reasons why our code instead uses
some 23.xxMHz value have long been lost in time. For the current shared
8250 implementation, the baud rate divisor for 115200 would be the same.

Correcting this does make the information in the coreboot table more
accurate and help payloads chose a better divisor, though.

bb9bdeb594 soc/rockchip/rk3399: Ensure full eDP init sequence
This patch fixes 2 edp display issues:

1. When rk_edp_prepare fails >3 times, edp_init isn't run because
while-condition is not satisfied. Then, only a partial init sequence is
ran. This causes all aux transactions to fail.
2. If rk_edp_prepare never succeeds, coreboot never leaves link training
stage due to infinite loop. Boot process is stuck.

TEST=Boot past eDP initialization stage and make sure AP logs don't have
show aux transaction fails.

5598db254f google/gru: Stop mucking with unused I2S0 pins in codec config
Due to a schematic error, our code was written to configure more I2S0
pins than are actually used. We're also pinmuxing the whole bank of pins
over to the I2S controller even though we don't need them all. Restrict
the GPIO initialization and pinmuxing to the pins we really need so the
other ones can be correctly used as SKU ID pins on Scarlet.

Also, move the "audio" IO voltage domain selection to the other such
selections in the bootblock, since that covers two whole banks of GPIOs
and there's no guarantee that they're all used for audio (and thus not
needed before ramstage).

BUG=b:69373077
TEST=Booted Scarlet, confirmed correct SKU ID (7) was detected on rev2.

029dfff30c i2c: Move to Linux like struct i2c_msg
Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.

Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.

The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.

Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.

Patched with Coccinelle using the clumsy spatch below and some manual
changes:

* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.

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.)

e085a8a359 rockchip/rk3399: enable DPLL SSC for DDR EMI test on bob
Spread Spectrum Modulator (SSMOD) is a fully-digital circuit used to
modulate the frequency of the Silicon Creations’ Fractional PLL in order
to reduce EMI.

We need to turn the DPLL spread spectrum feature on to
reduce the EMI noise for DDR on bob.

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.)
