Julius Werner 989e12bb63 arm: Fix stored PC value when handling exceptions
ARM processors save the PC value in the Link Register when they handle
and exception, but they store it with an added offset (depending on the
exception type). In order to make crashes easier to read and correctly
support more complicated handlers in libpayload, this patch adjusts the
saved PC value on exception entry to correct for that offset.

(Note: The value that we now store is what ARM calls the "preferred
return address". For most exceptions this is the faulting instruction,
but for software interrupts (SWI) it is the instruction after that. This
is the way most programs like GDB expect the stored PC address to work,
so let's leave it at that.)

Numbers taken from the Architecture Reference Manual at the end of
section B1.8.3.

samus: Convert mainboard to use soc/intel/broadwell

Switch from the haswell cpu/northbridge/southbridge interface
to the soc/intel/broadwell interface.

- Use new headers where appropriate
- Remove code that is now done by the SOC generic code
- Update GPIO map to drop LP specific handling
- Update INT15 handlers, drop all but the boot display hook

samus: Add some code to print basic info from SPD

The handling of LPDDR is a bit messy in Intel platforms.  There
is no traditional SPD so instead one is created by hand from the
provided datasheets.

These have varying (and sometimes unexpected) geometry and it can
be important during bringup to know what configuration is being
passed to the memory training code.

This could in theory be put in a more generic location, but for now
this is the only board with LPDDR3 where I have found it valuable.

TEST=Build and boot on samus, look for SPD details on the console.

Vadim Bendebury dffd892e47 ipq8064: modify SPI controller driver to work in coreboot
A typical SPI operation consists of two phases - command and data
transfers. Command transfer is always from the host to the chip (i.e.
is going in the 'write' direction), data transfer could be either read
or write.

We don't want the receive FIFO to be operating while the command phase
is in progress. A simple way to keep the receive FIFO shut down is to
not to enable it until the command phase is completed.

Selective control of the receive FIFO allows to consolidate the
receive and transmit functions in a single spi_xfer() function, as it
happens in other SPI controller drivers.

The FIFO FULL and FIFO NOT EMPTY conditions are used to decide if the
next byte can be written or received, respectively. While data is
being received the 0xFF bytes are transmitted per each received byte,
to keep the SPI bus clocking.

The data structure describing the three GSBI ports is moved from the
.h file into .c file. A version of the clrsetbits macro is added to
work with integer addresses instead of pointers.

BUG=chrome-os-partner:27784
TEST=not yet, but with the res of the changes the bootblock loads and
     starts the rombase section successfully.

Vadim Bendebury 11c4c92d91 ipq8064/storm: UART enable and various fixes
The original patch from chromium was  a bit of a mishmash.
Between that, rebasing and using the coreboot.org UART infrastructure,
the patch has changed a bit from the original. It seems reasonable to
keep these changes together.
- build in the ipq UART and turn on bootblock console
- sets LPAE and ROM header address
- adds cpd.c to storm

The original commit:
ipq8064: make UART driver work in bootblock

This patch it the last one in the chain adapting the ipq9064 UART
driver for use in coreboot. A new config option
(CONSOLE_SERIAL_IPQ806X) is being introduced to control inclusion of
the driver.

The previously introduced uart_wrapper.c is now included in the build
to provide the console driver structure used by ramstage.

Necessary configuration options are added to allow use of UART in the
bootblock.

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.

interface. Verified that the event times were accurate.

Julius Werner 83d1ba7e3d tegra: i2c: Add a timeout to I2C bit clear recovery mechanism
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.

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.
