For some panels, the plld can't provide the pixel clock that
the panels wants, so we give it a good enough one. And we
should calculate the dp/dc settings by the real pixel clock.
BRANCH=nyan
BUG=chrome-os-partner:29489
TEST=Verified the panels N116BGE-EA2(Nyan) and N133BGE-EAB(Big).
No screen flicker is observed. No sor dp fifo underflow found.

Our tests with the I2C bit clear mechanism (recovering from "lost
arbitration" errors) show that the bit clear hardware does not work
correctly in some situations. When a wedged slave device tries to send
more than one 0-to-1-to-0 transition to the host (e.g. leftover bits
from an aborted read), the controller never transitions the BC_ENABLE
bit back to zero.
This patch adds a long timeout to the bit clear code that waits for
register transitions as a safeguard. This way, We will still eventually
exit the function (probably followed by a reboot). Our tests show that
this will recover from all conditions after at most a few reboots.

This patch adds I2C emulation in software through raw toggling of the
SDA/SCL lines. Platforms need to provide bindings to toggle their
respective I2C busses for this to work (e.g. by pinmuxing them as GPIOs,
currently only enabled for Tegra).
This is mostly useful as a debugging feature, to drive unusual states on
a bus and closely monitor the device output without the need of a bus
analyzer. It provides a few functions to "wedge" an I2C bus by aborting
a transaction at certain points, which can be used to test if a system
can correctly recover from an ill-timed reboot. However, it can also
dynamically replace the existing I2C transfer functions and drive
some/all I2C transfers on the system, which might be useful if a driver
for the actual I2C controller hardware is not (yet) available.
Based on original code by Doug Anderson <dianders@chromium.org> and
Hung-ying Tyan <tyanh@chromium.org> for the ChromeOS embedded
controller project.

This is a fix for the 'Lost arb' we're seeing on Nyan* during
reboot stress testing. It occurs when we are slamming the
default PMIC registers with pmic_write_reg().
Currently, I've only captured this a few times, and the bus
clear seemed to work, as the PMIC writes continued (where
they'd hang the system before bus clear) for a couple of regs,
then it hangs hard, no messages, no 2nd lost arb, etc. So
I've added code to the PMIC write function that will reset the
SoC if any I2C error occurs. That seems to recover OK, i.e. on
the next reboot the PMIC writes all go thru, boot is OK, kernel
loads, etc.

Enable pinmux clamp function to avoid pinmux conflict.
For pins which are configured to tristate enabled, the inputs to the
controller will be clamped to zero. This can be used to avoid pinmux
conflicts since the tristate bit is set to 1 in the power-on-reset
pinmux setting.
With pinmux clamp enabled, we need to configure all the input pins

The new API is in use in depthcharge and is based around the "i2c_transfer"
function instead of i2c_read and i2c_write. The new function takes an array of
i2c_seg structures which represent each portion of the transfer after a start
bit and before the stop bit. If there's more than one segment, they're
seperated by repeated starts.
Some wrapper functions have also been added which make certain common
operations easy. These include reading or writing a byte from a register or
reading or writing a blob of raw data. The i2c device drivers generally use
these wrappers but can call the i2c_transfer function directly if the need
something different.
The tegra i2c driver was very similar to the one in depthcharge and was simple
to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
replace the ones in coreboot. The Exynos 5420 driver was ported from the high
speed portion of the one in coreboot and was straightforward to port back. The
low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
and were replaced with the depthcharge implementation.

To ensure that the command1 write which sets the "go" bit completes before
other reads to the device. Otherwise, there's a race condition where those
register values might still have their values from the last transfer. With
different SPI clock frequencies, that could lead to spi_delay being told there
were negative bytes still to send. Its expected delay would wrap to a negative
value, that was passed to udelay, and the system would sit there for 4 seconds
not doing anything.

This fixes two problems with the clock configuration on tegra124. First, the
macro which set up the i2c clocks tried to account for the fact that the i2c
divisor's lsb represents 1.0 where it normally represents 0.5 by multiplying
the target frequency by 2. That doesn't work, unfortunately, because the
divisor is actually n + 1, and what n + 1 means depends on where the one's
place is in the divisor.
Also, when calculating the divisor, the standard C division operator uses
truncation to deal any remainder which tends to make the divisor smaller. That
has the effect of making the output frequency higher than what was requested.
Since it's usually safer to undershoot a frequency than overshoot it, this
change makes those divisions round up instead.
Finally, the hand tuned temporary UART clock configuration was adjusted so
that it still ends up with the same divisor. Without that, very early output
from the bootblock is garbled, specifically the coreboot welcome banner,
build timestamp, etc.
BUG=chrome-os-partner:27220
TEST=Built and booted on nyan. Used a logic analyzer to verify that the TPM
i2c bus ran at 400KHz instead of 660KHz, and that the divisor was the expected
value. Measured boot time with and without EFS and verified that there was no
change. Spot checked the output for errors and verified that none of the
bootblock output was garbled.

The SPI drivers for tegra and exynos5420 have code in them which waits for a
frame header and leaves filler data out. The SPI driver shouldn't have support
for frame headers directly. If a device uses them, it should support them
itself. That makes the SPI drivers simpler and easier to write.
When moving the frame handling logic into the EC support code, EC communication
continued to work on tegra but no longer worked on exynos5420. That suggested
the SPI driver on the 5420 wasn't working correctly, so I replaced that with
the implementation in depthcharge. Unfortunately that implementation doesn't
support waiting for a frame header for the EC, so these changes are combined
into one.

to freeze. We have no idea does the write operation successful or not
before halting the AVP. And the power_on_main_cpu should be the last step
of that. So we make a fix to change the order.

This patch changes the ENTRY() macro in asm.h to create a new section
for every assembler function, thus providing dcache_clean/invalidate_all
and friends with the same --gc-sections goodness that our C functions
have. This requires a few minor changes of moving around data (to make
sure it ends up in the right section) and changing some libgcc functions
(which apparently need to have two names?), but nothing serious.
(You may note that some of our assembly functions have data, sometimes
even writable, within the same .text section. This has been this way
before and I'm not looking to change it for now, although it's not
totally clean. Since we don't enforce read-only sections through paging,
it doesn't really hurt.)
BUG=None
TEST=Nyan and Snow still boot. Confirm dcache_invalidate_all is not
output into any binary anymore since no one actually uses it.

The divider for the I2C clocks works differently than for other IP blocks and
needs to be set up to reflect that. There's also a large internal divider which
means you have to do extra calculations to determine what the frequency of the

desired frequency of the bus itself and figures everything else out.

This patch switches every last part of Coreboot on ARM over to Thumb
mode: libpayload, the internal libgcc, and assorted assembly files. In
combination with the respective depthcharge patch, this will switch to
Thumb mode right after the entry point of the bootblock and not switch
back to ARM until the final assembly stub that jumps to the kernel.
The required changes to make this work include some new headers and
Makefile flags to handle assembly files (using the unified syntax and
the same helper macros as Linux), modifying our custom-written libgcc
code for 64-bit division to support Thumb (removing some stale old files
that were never really used for clarity), and flipping the general
CFLAGS to Thumb (some more cleanup there as well while I'm at it).

This patch adds a new static assertion macro that can be used to check
the offsets in structures that overlay register sets at compile time. It
uses the _Static_assert() declaration from the new ISO C11 standard,
which is supported (even without -std=c11) by GCC after version 4.6.
(There is supposedly also support in clang, although I haven't tried
it... let's deal with compiler issues when/if they turn up.)
I've added it to all structures for our current ARM SoCs for now, and I
think every new register overlay we add going forward should use them
(at least for the last member, but feel free to add more if you think
it's useful).

tegra124: implement x2 mode for SPI transfers on CBFS media
This implements x2 mode when reading CBFS media over SPI.
In theory this effectively doubles our throughput, though the initial
results were almost negligibly better. Using a logic analyzer we see
a pattern of 12 clocks, ~70ns delay, 4 clocks, ~310ns delay. So if we
want to see further gains here then we'll probably need to tune AHB
arbitration and utilization to eliminate bubbles/stalls when copying
from APB DMA.

This patch adds stub implementations of exception_init() to all archs
so that it can be called from src/lib/hardwaremain.c. It also moves/adds
all other invocations of exception_init() (which needs to be rerun in
every stage) close to console_init(), in the hopes that it will be less
likely overlooked when creating future boards. Also added (an
ineffective) one to the armv4 bootblock implementations for consistency
and in case we want to implement it later.

The pins for the UART had been configured manually using hardcoded offsets and
values. Now that we have pinmux functions for that sort of thing, we should
use that instead. This also provides a very simple test for the pinmux code.
Ultimately this code should be wrapped in a function which handles setting up
any of the UARTs which is appropriately parameterized and which would be
called from the bootblock main instead of being in it, but for now this is
sufficient.

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

flags, this code can be re-introduced.

The pins on tegra are controlled by three different units, the pinmux, the
pin group controls, and the GPIO banks. Each of these units controls some
aspect of the pins, and they layer together and interact in interesting ways.
By default, the GPIOs are configured to pass through the special purpose IO
that the pinmux is configured to and so can be ignored unless a GPIO is needed.
The pinmux controls which special purpose signal passes through, along with
pull ups, downs, and whether the output is tristated. The pingroup controls
change the parameters of a group of pins which all have to do with a related
function unit.
The enum which holds constants related to the pinmux is relatively involved
and may not be entirely complete or correct due to slightly inconsistent,
incomplete, or missing documentation related to the pinmux. Considerable
effort has been made to make it as accurate as possible. It includes a
constant which is the index into the pinmux control registers for that pin,
what each of the functions supported by that pin are, and which GPIO it
corresponds to. The GPIO constant is named after the GPIO and is the pinmux
register index for the pin for that GPIO. That way, when you need to turn on
a GPIO, you can use that constant along with the pinmux manipulating functions
to enable its tristate and pull up/down mode in addition to setting up the
GPIO controls.
Also, while in general I prefer not to use macros or the preprocessor when
writing C code, in this case the set of constants in the enums was too large
and cumbersome to manage without them. Since they're being used to construct
a table in a straightforward way, hopefully their negative aspects will be
minimized.
In addition to the low level functions in each driver, the GPIO code also
includes some high level functions to set up input or output GPIOs since that
will probably be a very common thing to want to do.

A problem with including the tegra124 directory directly in the include path
is that it makes all headers in that directory first level headers available
everywhere including places that have nothing to do with the SOC, even headers
which were only intended for local use by tegra124 code. This change modifies
things a bit to be more like the way the arch headers are chosen. In the
tegra124 directory, there's an include directory which has an soc subdirectory
in it. That include directory is added to the include path, making it possible
to have headers private to the tegra124. When files specific to whatever tegra
is being built for are needed, you can include <soc/foo.h> and get the version
specific to that particular soc.
Also, the soc.h header file was overhauled to use enums instead of defines, to
consistently name things as far as their prefix (the less cryptic TEGRA instead
of NV_PA) and suffixes like "BASE", and to get rid of values which were
specific to U-Boot which we don't need. Since the only thing in the file were
address constants, I also renamed the file addressmap.h. It would be included
as:
<soc/addressmap.h>
which I think is easy to remember, does what you'd think it does from the
name, and won't conflict with other header files just minding their own
business in some other directory.

This change shows the source structure for nvidia Tegra and Tegra124
SOC. The problem we are trying to solve is that there is a large
amount of common code in the form of .c and .h files across many
different Tegra SOCs. The solution is to provide common code in a
single directory, but not to compile in the common code directory;
rather, we compile in a directory for a given SOC. Different SOCs
will sometimes need different bits of code from the common directory.
Tegra common code lives in tegra/, but there is no makefile there: if
a Tegra common file is needed in a SOC, it is referenced via a
Makefile in a specific Tegra SOC.
Another issue is includes. Include files in the common directory might be
accessed by a piece of code in an SOC directory. More problematically,
code in the common directory might require a file in an SOC directory.
We don't want to put the SOC name in an #include path, e.g.
in a C file in tegra/ is very undesirable, since we might be compiling
for a tegra114.
On some systems this is solved by a pre-pass which creates a set of
symbolic links; on others with nested #ifdef in the common code
which include different .h files depending on CPP variables.
In previous years, both LinuxBIOS and coreboot have tried these
solutions and found them inconvenient and error-prone.
We choose to solve it by requiring explicit naming of part of the path
of files that are in the common directory. This requirement, coupled
with two -I directives in the Makefile.inc, allows common and SOC
C code to incorporate both common and SOC .h files.
.c and .h files -- SOC or common -- name include
files in the common directory with the prefix tegra/, e.g.
SOC files will be included from the SOC directory if they have no prefix:
The full patch of clock.h will depend on what SOC is being compiled, which
is desirable.
In this way, a common file can pick up a specific SOC file without
creating symlinks or other such tricky magic.
We show this usage with one file, soc/nvidia/tega124/clock.c. This compiles.
The last question is where to put the prototype for the function
defined in this file -- soc.h?

It turns out there's a register in tegra which automatically counts at 1us
increments. It's primarily intended for hardware to use (I think to drive
other timers) but we can read it ourselves since a 1us timer is exactly what
we need to support the monotonic timer API.

These rules slip into the normal bootblock preperation process and use the
cbootimage utility to wrap it in a BCT.
