The originally loaded blinking program was written to allow gradual
change in LED brightness, which required controlling each LED with its
own engine. In fact there is no need in gradual brightness changes
when the firmware is controlling the ring. This allows to control all
LEDs by one engine, making the code simpler and more robust (no need
to synchronize the three engines any more).

The two controllers on the ring are programmed independently, and if
the second controller is running the old pattern while the first one
was loaded with a new pattern, there is a window of when the two
unrelated patterns might interact.
To avoid this shut down execution on both controllers before starting
downloading the new pattern code.

Add compiled lp55231 code snippets to allow display certain patterns
when booting the device with the recovery button pressed.
As soon as the press is detected, the low intensify solid white
pattern is enabled. Holding recovery button long enough causes the
device transition between the wipeout requested and recovery requested
states, with the appropriate changes in the displayed pattern.
The patch also includes the source code for the LED controller as well
as instructions on how to compile and modify the code to result in
different colors, intensities, blink periods and duty cycles.

The patterns displayed on the LED ring while under the coreboot
control are not driven by the vboot, but by the board code instead,
The four distinct states of the LED display are:
- all off
- recovery button push detected, waiting for it to be released
- wipeout request pending - recovery button was pushed long enough
to trigger this request
- recovery request pending - recovery button was pushed long enough
to trigger this request.

When in development environment, some SP5 devices might not have the
LED ring attached. They are still fully functional, but when booting
up are generating massive amount of i2c error messages. This patch
prevents accesses to non-existing lp55321 devices.
When loading the program into the device the vendor recommends 1 ms
delay when accessing the program control register. This patch
separates these accesses into a function and add a delay after every
access.
Another fix - advance the program address when loading multipage
programs.
Set the global variable register 3c, not used by coreboot programs, to
a fixed value. This will allow depthcharge to avoid re-initializing
the controller when not necessary.

unfortunately something about the new macro notation makes the compiler
evaluate it more efficiently (not recalculating the address between the
read and the write), so this was of limited value.

A payload may want to run erase operations on SPI NOR flash without
re-probing the device to get its properties. This patch passes up
three properties of flash to achieve that:
- The size of the flash device
- The sector size, i.e., the granularity of erase
- The command used for erase
The patch sends the parameters through coreboot and then libpayload.
The patch also includes a minor refactoring of the flash erase code.
Parameters are sent up for just one flash device. If multiple SPI
flash devices are probed, the second one will "win" and its
parameters will be sent up to the payload.
TEST=Observed parameters to be passed up to depthcharge through
libpayload and be used to correctly initialize flash and do an erase.
TEST=Winbond and Gigadevices spi flash drivers compile with the changes;
others don't, for seemingly unrelated reasons.

The AS3277 RTC code seems to closely follow the corresponding Linux
driver. Unfortunately, while coreboot (and even other parts of Linux,
like mktime()) directly follows the standard IBM PC RTC time
representation (except for the BCD part), Linux' struct rtc_time decided
to use 0-based (instead of 1-based) months instead.
This patch removes the faulty month offset that was copied into our
driver so that we will generate correct timestamps again.

Some SPI controllers (like Imgtec Pistachio), have a hard limit on SPI
read and write transactions. Limiting transfer size in the wrapper
allows to provide the API user with unlimited transfer size
transactions.
The tranfer size limitation is added to the spi_slave structure, which
is set up by the controller driver. The value of zero in this field
means 'unlimited transfer size'. It will work with existion drivers,
as they all either keep structures in the bss segment, or initialize
them to all zeros.
This patch addresses the problem for reads only, as coreboot is not
expected to require to write long chunks into SPI devices.

CL:243671 moved the initialization of elog_initialized around, which is
now unfortunately so late that the ELOG_TYPE_BOOT event gets omitted
because the code believes the log to be broken at that time. Good thing
we now have a FAFT test for these things that I had of course been too
lazy to run. -.-
The real reason for moving that line was to put it after any point in
elog_init() that could still error out. The problem is that we might add
the "cleared" event before we try to shrink (which can fail and cause an
error)... but those two things cannot happen at the same time, so it
should be okay to flip them around and mark the elog as initialized in
between.

The elog driver has a really stupid bug that checks a result which is
stored in an unsigned variable for < 0. Surprisingly GCC does not catch
this nonsense right now, and I spent an hour trying out different
warning options without finding one that doesn't also bring a load of
stupid and unavoidable false positives (the biggest offender being
-Wtype-limits, which does exactly what we'd want except for flagging
things like if ((u8)var >= CONFIG_VAR_MIN) where the VAR_MIN Kconfig may
or may not be 0).
So, the only thing we can do is fix this one and wait for the next time
something like that blows up. -.- Also change some more code to make the
behavior more explicit (the old code already intended to work this way
since flash_base is statically initialized to 0, never assigned in the
error path and checked later in elog_init()... but there was an error
message that incorrectly claimed a different fallback behavior, and
explicitly assigning the values makes this easier to see). Finally, add
another state to the elog_initialized variable to avoid trying to
reinitialize a broken eventlog on every event (if it doesn't work the
first time, chances are that it won't work later on during the same boot
either).

The TPM driver by default allocates a 4K transfer buffer on the stack,
which leads to lots of fun on boards with 2K or 3K stack sizes. On
RK3288 this ends up writing over random memory sections which dependent
on the memlayout of the day might contain timestamp data (no big deal)
or page tables (-> bad time).
This patch fixes the problem by reducing the buffer size to slightly
above 1K, which still seems to work as far as I can tell. There was
already some really odd code that #undef'ed this value and redefined it
with the lower number in one .c file (unfortunately not the one with the
buffer declaration), with no explanation whatsoever... I'm removing that
and just assume the smaller value will be fine for everything.

This adds a ramstage driver for the TPM and allows the interrupt
to be configured in devicetree.cb.
The interrupt vector is set like other PNP devices, and the
interrupt polarity is set with a register configuration variable.
These values are written into locality 0 TPM_INT_VECTOR and
TPM_INT_ENABLE and then all interrupts are disabled so they are
not used in firmware but can be enabled by the OS.
It also adds an ACPI device for the TPM which will configure the
reported interrupt based on what has been written into the TPM
during ramstage. The _STA method returns enabled if CONFIG_LPC_TPM
is enabled, and the _CRS method will only report an interrupt if one
has been set in the TPM itself.
The TPM memory address is added by the driver and declared in the
ACPI code. In order to access it in ACPI a Kconfig entry is added for
the default TPM TIS 1.2 base address. Note that IO address 0x2e is
required to be declared in ACPI for the kernel driver to probe correctly.

Come to think of it, it is perfectly fine to use a statically

The GCC 4.9.2 update showed that the boot_state_init_entry
structures were being padded and assumed to be aligned in to an
increased size. The bootstate scheduler for static entries,
boot_state_schedule_static_entries(), was then calculating the
wrong values within the array. To fix this just use a pointer to
the boot_state_init_entry structure that needs to be scheduled.
In addition to the previous issue noted above, the .bs_init
section was sitting in the read only portion of the image while
the fields within it need to be writable. Also, the
boot_state_schedule_static_entries() was using symbol comparison
to terminate a loop which in C can lead the compiler to always
evaluate the loop at least once since the language spec indicates
no 2 symbols can be the same value.

This patch has a rather twisted history. It was originally split off
from a chromium patch, which moved ALTCENTURY to Kconfig. However,
since we have no user without ALTCENTURY, we've agreed that the best
way to proceed is to eliminate the non-ALTCENTURY case entirely.
The old commit message and identifiers are kept below for reference:
The availability of "ALTCENTURY" is now set through a kconfig
variable so it can be available to the RTC driver without having to have a
specialized interface.
BUG=None
TEST=Built and booted on Link with the event log code modified to use the RTC
interface. Verified that the event times were accurate.

Coreboot has all necessary infrastructure to use the proper SPI flash
interface in bootblock for CBFS. This patch creates a common CBFS
wrapper which can be enabled on different platforms as required.
COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the
common CBFS interface and prevents default inclusion of all SPI chip
drivers, only explicitly configured ones will be included when the new
feature is enabled. Since the wrapper uses the same driver at all
stages, enabling the new feature will also make it necessary to
include the SPI chip drivers in bootblock and romstage images.
init_default_cbfs_media() can now be common for different platforms,
and as such is defined in the library.

This consolidates all calls to spi_claim_bus() and spi_release_bus()
to a single location where spi_xfer() is called. This avoids confusing
(and potentially redundant) calls that were being done throughout the
generic spi_flash.c functions and chip-specific functions.
I don't think the current approach could even work since many chip
drivers assert /CS once and then issue multiple commands such as page
program followed by reading the status register. I suspect the reason
we didn't notice it on x86 is because the ICH/PCH handled each
individual command correctly (spi_claim_bus() and spi_release_bus()
are noops) in spite of the broken code.

This adds a wrapper function and a Kconfig variable to differentiate
between SPI controllers which use atomic cycle sequencing versus
those where the transaction sequence is controlled manually. Currently
this boils down to x86 vs. non-x86.
Yes, it's hideous. The current API only worked because, for better or
worse, x86 platforms have been homogeneous in this regard since they
started using SPI as an alternative to FWH for boot flash. Now that
we have non-x86 platforms which use general purpose SPI controllers,
we should overhaul the entire SPI infrastructure to be more adaptable.

- Translate flash offset to memory-mapped address only on x86.
- Guard ACPI-dependent line of code
- Use a Kconfig variable for SPI bus when probing the flash rather
than assuming the bus is always on bus 0.
- Zero-out timestamp on non-x86 until we have a better abstraction.

This severs a dependency the eventlog code has on initializing
chipset/SoC SPI controller. Currently elog_init() calls spi_init()
as a catch-all. This worked for x86 since the SPI controller is only
used for one thing on existing platforms. As we add eventlogging
support to non-x86 platforms we need to consider the more generalized
case where the assumptions about how SPI works on x86 are no longer
valid.

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.

This replaces a hard-coded bus number of 0 with a Kconfig variable,
CONFIG_BOOT_MEDIA_SPI_BUS. This removes an assumption made for x86
where this value is always 0 and makes it easy to add support for
other platforms where the bus number for the backing SPI flash is
more arbitrary.
BUG=none
BRANCH=none
TEST=tested on Nyan (bus=4) and Link (bus=0)

For some UART hardware registers are 32 bits wide, so we will need
base_port + reg << 2 instead. Prepare for that change and unification of
MMIO between ARM and x86.

Depending on the platform the underlying regions vboot requires
may not be accessible through a memory-mapped interface. Allow
for non-memory-mapped regions by providing a region request
abstraction. There is then only a few touch points in the code to
provide compile-time decision making no how to obtain a region.
For the vblocks a temporary area is allocated from cbmem. They
are then read from the SPI into the temporarily buffer.
BUG=chrome-os-partner:27094
BRANCH=None
TEST=Built and booted a rambi with vboot verification.
