Martin Roth 2507820bd9 src/include: Doxygen fixes
- Join doxygen file command with the file description
- Give extended file location so doxygen knows which early_sbmus.h
the file is.  (I don't get this either, but it fixes the warning)

Stefan Reinauer 5491ca23fc cpu: Drop print_ implementation from non-romcc boards
Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*. Back in the day, like more than
half a decade ago, we migrated a lot of boards to printk, but we never
cleaned up the existing code to be consistent. instead, we worked around
the problem with a very messy console.h (nowadays the mess is hidden in
romstage_console.c and early_print.h)
This patch cleans up the cpu code to use printk() on all non-ROMCC
boards.

Sheng-Liang Song 1d6560fc60 chromeos: Unconditionally clear the EC recovery request
Add the empty weak function clear_recovery_mode_switch().

Problem:
If GBB_FLAG_DISABLE_EC_SOFTWARE_SYNC is set,
the following will happen:

1. Boot device in recovery mode with Esc + F3 + Pwr.
2. Turn device off with Pwr button.
3. Turn device on with Pwr button.

Device still boots to recovery screen with
recovery_reason:0x02 recovery button pressed.

If GBB_FLAG_DISABLE_EC_SOFTWARE_SYNC isn't set, turning the
device off and on again  with the Pwr button does a normal boot.

Solution:
Unconditionally clear the recovery flag.

Gabe Black 03abaee219 drivers/pc80/mc146818rtc: Assume we always have ALTCENTURY
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.

TEST=Built and booted on Link with the event log code modified to use the RTC
interface. Verified that the event times were accurate.

Julius Werner 37d7ac8b5b i2c: Add software_i2c driver for I2C debugging and emulation
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.

Gabe Black cdb61a6f5d i2c: Replace the i2c API.
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.

Gabe Black e5b21274bd tegra124: A couple clock fixes.
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.
BRANCH=None

Had to add the stdlib.h from 89ed6c that hadn't been merged correctly.

To backport features introduced with recent Chromebooks and/or Intel
boards in general, heavy work on the AMD AGESA platform infrastructure

members have little means to verify, debug and develop for the said

Thus it makes sense to fork the existing agesawrapper interfaces, to give
AMD PI platforms a clean and independent sandbox. New directory layout
reflects the separation already taken place under 3rdparty/ and vendorcode/.

Kyösti Mälkki abc083e06b AMD (K8/fam10): Rewrite CAR migration in post_cache_as_ram
Old routine copied all of CAR region as-is right below CONFIG_RAMTOP.
Most of this region was reserved to interleave AP CPU address spaces
and unused on BSP CPU. The only part of CAR region requiring a copy
in RAM is the sysinfo structure.

Improved routine changes this as follows:

A region of size 'backup_size' below CONFIG_RAMTOP is cleared. In
case of S3 resume, OS context from this region is first copied to
high memory (CBMEM_ID_RESUME).

At stack switch, CAR stack is discarded. Top of the stack for BSP
is located at 'CONFIG_RAMTOP - car_size' for the remaining part
of the romstage. This region is part of 'backup_size' and was zeroed
before the switch took place.

Before CAR is torn down the region of CAR_GLOBALS (and CAR_CBMEM),
including the relevant sysinfo data for AP nodes memory training,
is copied at 'CONFIG_RAMTOP - car_size'.

NOTE: While CAR_GLOBAL variables are recovered, there are currently
no means to calculate their offsets in RAM.

NOTE: Boards with multiple CPU packages are likely already broken since

  bbc880ee amdk8/amdfam10: Use CAR_GLOBAL for sysinfo

This moved the copy of sysinfo in RAM from above the stack to below
the stack, but code for AP CPU's was not adjusted accordingly.

Gabe Black b3f08c61f1 cmos: Rename the CMOS related functions.
Most of the code related to the mc146818 is not related to the RTC and is
really for managing the CMOS storage. Since we intend to add a generic API
for RTC drivers it's inconvenient for those functions to have an rtc_ prefix.
This CL renames those functions so they start with cmos_ instead. There are
some places where rtc_init was called with a comment that says something about
starting the RTC. That wasn't correct before (the RTC is always running), but
it looks a little odd now that the function is called cmos_init.

This CL also opportunistically cleans up some style problems in this file.
