9a6ca071e0 peppy: Add 2GB DRAM configuration.
Currently, all Peppy boards w/ '000' SPD GPIOs have 2GB DRAM. Disable
the second DRAM channel based upon the GPIOs.

Need to change / confirm this for upcoming builds.

91bd0b8419 Add description to MAINBOARD_VENDOR string so it can be overridden
A quirk of the Kconfig used in coreboot is that config options
cannot be overriden by local config changes unless they have
a description string.

1) Add CONFIG_MAINBOARD_VENDOR="Custom" to local config
2) Build and flash coreboot
3) cat /sys/class/dmi/id/sys_vendor and look for "Custom"

Configure interrupt GPIOs as PIRQ type and wake GPIOs as
just standard input type.  The wake GPIO is reconfigured as
ACPI SCI in the specific device _DSW method.  This prevents
the wake GPIO from generating a flood of SCI at runtime.

LTE_WAKE_L_Q and WLAN_WAKE_L_Q are left as ACPI SCI as these
are not repurposed interrupt pins so they are not generated
at runtime.

SIM_DET and ALS_INT_L are set as input since we don't have an

tested on slippy with trackpad with additional
kernel changes to chromeos_laptop.c to initialize devices.

1) Ensure trackpad interrupt is functional and that there
is not a flood of ACPI SCI when trackpad does interrupt:
  9:          1          0          0          0   IO-APIC-fasteoi   acpi
 37:        421          0          0          0   IO-APIC-fasteoi   cyapa

2) Ensure that devices are exposed as wake capable:
Device  S-state   Status   Sysfs node
TPAD      S3    *enabled   pnp:00:00
TSCR      S3    *disabled  pnp:00:01

3) Ensure that trackpad can wake from S3 by default, but
that it does not cause an immediate wake when entering suspend.

4) Ensure that trackpad can be disabled as a wake source with
echo TPAD > /proc/acpi/wakeup

d7cb8d074f lynxpoint: Change SerialIO device enable reporting to ACPI
In order to report whether coreboot enabled a SerialIO device
in ACPI mode we had been relying on reading NVS in the _STA
method for the SerialIO device.

The ACPI _STA method has restrictions on what it can access
and is unable to access OperationRegions outside its scope
which means it should not be trying to read NVS.

This change adds a new SSDT to the ACPI tables and fills it
with constants that indicate whether or not a device is enabled
in ACPI mode.

The ACPI code is changed to read these variables from the
SSDT and use that instead of trying to query a variable in NVS.

Attempt to use lpt-clk driver to probe the
device clocks for SerialIO devices and see that the kernel
does not complain about accessing the GNVS region.

d686acd1a3 pit: Redo the display port bridge initialization code.
The display port bridge on pit is different from the one on snow and needs to
be initialized differently. Instead of waiting for the chip to come up on its
own and assert the hotplug detect, we need to access it over i2c and get it up
and running ourselves.

c0b2144f69 pit: Replace the tps65090 functions and adjust the hotplug detect line.
The functions which manipulated the tps65090 were removed a while ago because
it isn't accessible directly from the AP, it's on an I2C bus that has to be
accessed by the EC on our behalf. Now that that capability has been added, we
can rewrite the small portion of the the tps65090 we actually used but using
the EC passthrough commands.

Also, we should not be configuring the hardware display port hotplug detect
line since we're using it as a GPIO for other purposes. The GPIO we're using
instead defaults to being an input, but to be safe we should probably
explicitly configure it as one anyway.

fe6406033f exynos5250: De-switch-ify the pinmux configuration code.
The pinmux code for the exynos5250 was all bundled into a single, large
function which contained a switch statement that would set up the pins for
different peripherals within the SOC. There was also a "flags" parameter, the
meaning of which, if any, depended on which peripheral was being set up.

There are several problems with that approach. First, the code is inefficient
in both time and space. The caller knows which peripheral it wants to set up,
but that information is encoded in a constant which has to be unpacked within
the function before any action can be taken. If there were a function per
peripheral, that information would be implicit. Also, the compiler and linker
are forced to include the entire function with all its cases even if most of
them are never called. If each peripheral was a function, the unused ones
could be garbage collected.

Second, it would be possible to try to set up a peripheral which that function
doesn't know about, so there has to be additional error checking/handling. If
each peripheral had a function, the fact that there was a function to call at
all would imply that the call would be understood.

Third, the flags parameter is fairly opaque, usually doesn't do anything, and
sometimes has to have multiple values embedded in it. By having separate
functions, you can have only the parameters you actually want, give them
names that make sense, and pass in values directly.

Fourth, having one giant function pretends to be a generic, portable API, but
in reality, the only way it's useful is to call it with constants which are
specific to a particular implementation of that API. It's highly unlikely that
a bit of code will need to set up a peripheral but have no idea what that
peripheral actually is.

Call sights for the prior pinmux API have been updated. Also, pinmux
initialization within the i2c driver was moved to be in the board setup code
where it really probably belongs. The function block that implements the I2C
controller may be shared between multiple SOCs (and in fact is), and those
SOCs may have different pinmuxes (which they do).

Other places this same sort of change can be made are the pinmux code for the
5420, and the clock configuration code for both the 5250 and the 5420.

u-boot is not common code at all but very specific to the 5250 and
not compatible with the 5450. Hence, unify the directories exynos5250
and exynos5-common. We will try to factor out common code while
progressing with the 5450 port.

043eb0e35f Wield battle axe at ARM port
This patch unfortunately incorporates a number of changes,
all of which are making future ARM ports easier.

 - drop cruft that came in with u-boot
 - move serial console from mainboard Kconfig to Exynos Kconfig
 - factor out non-board specific wakeup code
 - move generic bootblock code from mainboard to Exynos
 - actually call arch_cpu_init()
 - remove dead code
 - fix up copyright messages
 - remove snow_ prefix from a lot of code to reduce the noise
   when creating a new mainboard based on that code.

b2893a0169 Provide support for setting up the framebuffer from EDID
Add three functions to edid.c:

void set_vbe_mode_info_valid(struct edid *edid, uintptr_t fb_addr)
takes an edid and uintptr_t, and fills in a static lb_framebuffer struct
as well as setting the static vbe_valid to 1 unless some problem
is found in the edid. The intent here is that this could be called from
the native graphics setup code on both ARM and x86.

int vbe_mode_info_valid(void)
returns value of the static vbe_valid.

void fill_lb_framebuffer(struct lb_framebuffer *framebuffer)
copies the static edid_fb to lb_framebuffer.

There is now a common vbe.h in src/include, removed the two special ones.

In general, graphics in coreboot is a mess, but graphics is always a
mess.  We don't have a clean way to try two different ways to turn on
a device and use the one that works. One battle at a time. Overall,
things are much better.

The best part: this code would also work for ARM, which also uses EDID.

time.h We Hardly Knew Ye.

This deprecates time.h which is currently only used by Exynos5250 and

interfaces and has been supplanted by the monotonic timer API.

timer_us() is now obsolete. timer_start() is now mct_start() and

With that timer change, the wake up state test procedure can be simplified.

bf92b19b2a Google/Snow: Temporary fix for resume failure.
The DDR3 memory initialization (with "mem_reset" set on normal boot) will cause
resume to be unstable, especially when X is running. System may show X screen
for few seconds, then crash randomly and unable to recover - although text
console may still work for a while.  Probably caused by corrupted memory pages.

'mem_reset' (which refers to RESET# in DDR3 spec) should be enabled according
to DDR3 spec. But it seems that on Exynos 5, memory can be initialized without
setting mem_reset for both normal boot and resume - at least no known failure
cases are found yet.  So this can be a temporary workaround.

Verified by booting a Google/Snow device with X Window and ChromeOS, entering
browser session with fancy web pages, closing LID to suspend for 5 seconds, then
re-opening to resume.  Suspend/resume worked as expected.

Also tried the "suspend_stress_test" with X running and finished 100 iterations
of suspend/resume test without failure.

6bfbb33a64 ec/google: Support Google's Chrome EC on I2C interface.
Google's Chrome EC can be installed on LPC or I2C bus, using different command
protocol.  This commit adds I2C support for devices like Google/Snow.

Note: I2C interface cannot be automatically probed so the bus and chip number
must be explicitly set.

Verified by booting Google/Snow, with following console output:
  Google Chrome EC: Hello got back 11223344 status (0)
  Google Chrome EC: version:
     ro: snow_v1.3.108-30f8374

cd4c8c1e0e exynos5/snow: remove wait_ms arg from dp_controller_init()
This removes the wait_ms argument from the dp_controller_init(). The
only delay involved is a constant 60ms delay that happens if
everything else goes well. This delay is derived from the LCD spec
so there's no reason it should be baked into the controller code.

(This patch also has the side-effect of fixing a bug where we were
delaying on an undefined value for wait_ms).

c0b972f60d Exynos5250: add a microsecond timer
Add a microsecond timer, its declaration, the function to start it,
and its usage.  To start it, one calls timer_start().  From that point
on, one can call timer_us() to find microseconds since the timer was
started.

We show its use in the bootblock. You want it started very early.

Finally, the delay.h change having been (ironically) delayed, we
create time.h and have it hold one declaration, for the timer_us() and
timer_start() prototype.

We feel that these two functions should become the hardware specific
functions, allowing us to finally move udelay() into src/lib where it
belongs.

1a5c9cd33b Snow: Set up the ChromeOS GPIOs as inputs during the ROM stage.
We need these to be inputs so they can be read when populating the coreboot
tables. It seems like a good idea to do this early to ensure that the input
gate capacitance has had a chance to charge, and if we decide to use
actually use that information during the ROM stage to do earlier RW
firmware selection.

It is not guarded by a ChromeOS config variable because those lines are
always intended to be input GPIOs, regardless of whether we're running
ChromeOS or not.

b959fbb87a exynos5: Re-factor I2C code
This re-factors the Exynos5 I2C code to be simpler and use the
new API, and updates users accordingly.

- i2c_read() and i2c_write() functions updated to take bus number
  as an argument.

- Get rid of the EEPROM_ADDR_OVERFLOW stuff in i2c_read() and
  i2c_write(). If a chip needs special handling we should take care
  of it elsewhere, not in every low-level i2c driver.

- All the confusing bus config functions eliminated. No more
  i2c_set_early_config() or i2c_set_bus() or i2c_get_bus(). All this
  is handled automatically when the caller does a transaction and
  specifies the desired bus number.

- i2c_probe() eliminated. We're not a command-line utility.

- Let the compiler place static variables automatically. We don't need
  any of this fancy manual data placement.

- Remove dead code while we're at it. This stuff was ported early on
  and much of it was left commented out in case we needed it. Some
  also includes nested macros which caused gcc to complain.

- Clean up #includes (no more common.h, woohoo!), replace debug() with
  printk().

cfb73607be replace device/i2c.h with simpler version
The existing header was imported along with the Exynos code and left
mostly unchanged. This is the first patch in a series intended to
replace the imported u-boot I2C API with a much simpler and cleaner
interface:

- We only need to expose i2c_read() and i2c_write() in our public API.
  Everything else is board/chip-dependent and should remain hidden
  away.

- i2c_read and i2c_write functions will take bus number as an arg
  and we'll eliminate i2c_get_bus and i2c_set_bus. Those are prone to
  error and end up cluttering the code since the user needs to save
  the old bus number, set the new one, do the read/write, and restore
  the old value (3 added steps to do a simple transaction).

- Stop setting default values for board-specific things like SPD
  and RTC bus numbers (as if we always have an SPD or RTC on I2C).

- Death to all the trivial inline wrappers. And in case there was any
  doubt, we really don't care about the MPC8xx. Though if we did then
  we would not pollute the public API with its idiosyncrasies.

The device tree has been changed enough so that, at the very least, the correct
functions are called at the correct time, with the correct paramaters. We
decided to yank the I2C entries as they did not obvious function and might
not even have been correct.

Not working, seemingly, but we need to add a 4M resource for
memory, and it seems it needs to be fixed at the address shown.
This address was chosen from current hardware.

We realized that the display code should be part of the cpu -- that's how
the hardware works!

you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.

Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

a95a13bd47 link/graphics: New state machine
This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.

As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.

A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.

The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.

The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.

This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.

i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.

bba8090421 armv7/exynos/snow: new cache maintenance API
This adds a new API for cache maintenance operations. The idea is
to be more explicit about operations that are going on so it's easier
to manage branch predictor, cache, and TLB cleans and invalidations.

Also, this adds some operations that were missing but required early
on, such as branch predictor invalidation. Instruction and sync
barriers were wrong earlier as well since the imported API assumed
we compield with -march=armv5 (which we don't) and was missing
wrappers for the native ARMv7 ISB/DSB/DMB instructions.

For now, this is a start and it gives us something we can easily use
in libpayload for doing things like cleaning and invalidating dcache
when doing DMA transfers.

TODO:
- Set cache policy explicitly before re-enabling. Right now it's left
  at default.
- Finish deprecating old cache maintenance API.
- We do an extra icache/dcache flush when going from bootblock to
  romstage.

aeda4b8c0a src/mainboard: Drop redundant CHIP_NAME again for new ports
Since commit »Drop redundant CHIP_NAME in mainboard.c« (a93c3fe7) [1]
`CHIP_NAME` is unneeded for mainboards as the name is composed
automatically in `src/devices/root_device.c` from the strings in
Kconfig.

Unfortunately the ports for Google Butterfly, Link and Parrot as
as well as IEI PM-LX2-800-R10 introduced CHIP_NAME again. So drop
it again too.

d2bed05e6a exynos5250/snow: call PMIC's power_init() function
Call the power_init() function. We appear to have forgotten about it
when deprecating lowlevel_init_subsystems(), but it didn't seem to
cause problems until we got to doing more interesting stuff recently.

There are some clean-ups to do from the original code, such as not
attempting to configure I2C from PMIC code, which we'll get around
to in follow-up patches.

b21eaa74a6 ARMV7 and Google/Snow: Add exception support code to the ramstage
This is previously used exception code from libpayload.
On startup it installs and then tests an exception handler.
The test is an unaligned memory operation.

Yes, we've seen what might be exceptions in the ramstage, and
it makes sense to handle them. This code is identical in structure
and operation to the previously committed payload exception handler,
though we reserve the right to change it as circumstances require.

The remaining question is whether we need it in romstage.

6bde149d9c samsung/exynos5: add display port and framebuffer defines and initialization
These are essential functions for setting up the display port and
framebuffer, and also enable such things as aux channel
communications.  We do some very simple initialization in romstage,
mainly set a GPIO so that the graphics is powering up, but the complex
parts are done in the ramstage. This mirrors the way in which graphics
is done in the x86 size.

I've added a first pass at a real device, and put it in the mainboard
Kconfig, hoping for corrections. Because startup is so complex,
depending on device type, I've created a 'displayport' device that
removes some of the complexity and makes the flow *much* clearer.  You
can actually follow the flow by looking at the code, which is not true
on other implementations. Since display port is perhaps the main port
used on these chips, that's a reasonable compromise. All parameters of
importance are now in the device tree.

f4861df1e7 google/snow: Change MMC0 to work in 8 bit mode.
The MMC0 on google/snow can run in 8 bit mode. To simplify driver development,
we thought disabling it (using zero, which runs in 1-bit / 4-bit mode) may help.

However, after some experiments in payload drivers, setting pinmux to 8 bit mode
can still allow MMC to run in 1-bit / 4-bit mode, so it's pretty safe to enable
8 bit mode by default for better performance.

Verified to boot on google/snow, and got MMC0 working.

5d994634a2 armv7/exynos5250/snow: deprecate CONFIG_{RAMBASE,RAMTOP}
RAMBASE and RAMTOP are leftovers from the x86 port and do not apply
the same way on ARM platforms. On x86 they refer to the low memory
region where coreboot tables reside.

However on ARM we don't have such a region which is architecturally
defined. So instead we'll use the CPU-defined DRAM base address and
the mainboard-defined DRAM size.

0b153bdda9 exynos/snow: move SPI GPIO setup to mainboard bootblock code
This moves GPIO setup from chip-specific SPI code to mainboard-
specific bootblock code. This makes exynos_spi_open a bit more
generic so it can eventually be used for any SPI channel. This
also benefits CBFS since the user can set media->context to
to any set of SPI registers.

0d4f97e270 exynos/snow: Move core/memory clock-related and board ID code
This patch moves ARM core and DRAM timing functions around to simplify
the dependencies for system_clock_init().

The original code was architected such that the system_clock_init()
function called other functions to obtain core and memory timings.
Due to the way memory timing information must be obtained on Snow,
which entails decoding platform-specific board straps, the bottom-
up approach resulted in having the low-level clock init code
implicitly depend on board and vendor-specific info:

main()
  ->system_clock_init()
    -> get_arm_ratios()
       -> CPU-specific code
    -> clock_get_mem_timings()
       -> board_get_revision()
          -> read GPIOs (3-state logic)
          -> Decode GPIOs in a vendor-specific manner
       -> Choose memory timings from module-specific look-up table
  ...then proceed to init clocks
...come back to main()

The new approach gathers all board and vendor-specific info in a
more appropriate location and passes it into system_clock_init():
main()
  -> get_arm_ratios()
     -> CPU-specific code
  -> get_mem_timings()
     -> board_get_config()
        -> read GPIOs (3-state logic)
        -> Decode GPIOs in a vendor-specific manner
     -> Choose memory timings from module-specific look-up table
  -> system_clock_init()
...back to main()

2354ef8869 exynos/snow: get rid of board-specific arbitration code
Snow's AP, EC, PMU, and smarty battery share a bus. Both the AP and
EC can act as a master, so to avoid conflicts an arbitration
mechanism consisting of two GPIOs is used.

By default, the AP "owns" the bus unless it is off (in which case
the EC doesn't monitor the arbitration pins). This means the boot
firmware does not need to worry about these lines. The payload may
if it needs to communicate with the EC, though.

In any case, board-specific bus arbitration logic does not belong
in a low-level driver that is supposed to be generic for an entire
CPU family. If the payload needs to talk to the EC, we'll deal with
it there.

For ARM platform, the bootblock may need more C source files to initialize

dependency by using #include inside bootblock.c, we should add a new build class

Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled
for boot block.

For x86, the bootblock is limited to fewer assembly files so it's not using this
class. (Some files shared by x86 and arm in top level or lib are also changed
but nothing should be changed in x86 build process.)

6fe0cab205 Extend CBFS to support arbitrary ROM source media.
Summary:
	Isolate CBFS underlying I/O to board/arch-specific implementations as
	"media stream", to allow loading and booting romstage on non-x86.

	CBFS functions now all take a new "media source" parameter; use
	CBFS_DEFAULT_MEDIA if you simply want to load from main firmware.
	API Changes:
		cbfs_find => cbfs_get_file.
		cbfs_find_file => cbfs_get_file_content.
		cbfs_get_file => cbfs_get_file_content with correct type.

CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM,
the ROM may come from USB, UART, or SPI -- any serial devices and not available
for memory mapping.

To support these devices (and allowing CBFS to read from multiple source
at the same time), CBFS operations are now virtual-ized into "cbfs_media".  To
simplify porting existing code, every media source must support both "reading
into pre-allocated memory (read)" and "read and return an allocated buffer
(map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*"
provides simple memory mapping simulation.

Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA
is defined for CBFS functions to automatically initialize a per-board default
media (CBFS will internally calls init_default_cbfs_media).  Also revised CBFS
function names relying on memory mapped backend (ex, "cbfs_find" => actually
loads files). Now we only have two getters:
	struct cbfs_file *entry = cbfs_get_file(media, name);
	void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type);

Test results:
 - Verified to work on x86/qemu.
 - Compiles on ARM, and follow up commit will provide working SPI driver.

This patch does a few things to get us into romstage:
- Add romstage as a stage (a later patch adds it as a binary, which
  is probably wrong). The Makefile magic is complex enough that we
  let it build the XIP file for now, but we no longer use it.

- Replace findstage with loadstage. Loadstage will find a stage,
  load the code to memory, and zero the remaining part of memory.
  Now we can link the romstage to go anywhere!

- Eliminate magic offsets from code/ldscripts and centralize Kconfig
  variables in src/cpu/samsung/exynos5250/Kconfig.

- Tidy up code and serial output

929f9f1719 armv7: add a wrapper for romstage's main() for ARM ISA
This adds a wrapper around main() in romstage which is compiled using
-marm. This assumes that the bootblock branches to romstage in ARM
mode.

The long-term idea is to enforce ABI compatibility when handing off to
the next stage by using shims which are which are compiled in a pre-
determiend manner and leave the main portions of each stage up to
whatever the compiler wants. So it will eventually look like this:
1. bootblock_main (ARM/Thumb)
2. bootblock_exit (ARM)
3. romstage_entry (ARM)
4. romstage_main (ARM/Thumb)

d3c7530908 import SPL files for board_i2c_{claim,release}_bus()
This imports SPL (second phase loader) files from U-Boot. Most of the
content of these files will eventually go away since they're fairly
U-Boot specific. For now they are here to make Jenkins happy.

f89e6b22c0 Add minimal mainboard support for snow
This is the minimal set of sources that allow the board to build.
These need to be filled in with actual code. But if we get these in upstream
we can stop working against a WIP patch.
