320647abda vboot2: add verstage
Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains, compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with verstage_.

TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

4a810ba2d6 nyan*: I2C: Fix bus clear BC_TERMINATE naming.
In the original fix for the 'Lost arb' we were seeing on
Nyan* during reboot stress testing, I had the name of
BC_TERMINATE's bit setting wrong. Fix this to use the
IMMEDIATE (1) setting. The setting didn't change, just
the name. According to Julius this is the optimal
setting for bus clear in this instance. Also widened
the SCLK_THRESHOLD mask to 8 bits as per spec.

749559b1fb tegra124: fix and fine tune the warm boot code
We assume that the clock rate of SCLK/HCLK/PCLK was 408MHz which was same
as PLLP. But that is incorrect, BootROM had switched it to pllp_out2
with the rate 204MHz. So actually the warm boot procedure was running at
the condition of SCLK=HCLK=PCLK=pllp_out2 with the rate 204MHz.

And the CPU complex power on sequences were different with what we used
in kernel and Coreboot. Fix up the sequence as below.
* enable CPU clk
* power on CPU complex
* remove I/O clamps
* remove CPU reset

Update the time of the CPU complex power on function for record.
* power_on_partition(PARTID_CRAIL): 528 uSec
* power_on_partition(PARTID_CONC): 0 uSec
* power_on_partition(PARTID_CE0): 4 uSec

Finally, removing the redundant routine of a flow controller event with
(20 | MSEC_EVENT | MODE_STOP).

This patch adds code to initialize the two DWC3 USB host controllers and
their associated PHYs to the IPQ806x SoC (closely imitating the existing
DWC3 implementation for Exynos5), and uses them to initialize USB on the
Storm mainboard.

BUG=chrome-os-partner:29375
TEST=Hack up netboot to get around missing SPI flash, load a file over
TFTP. Hack a storage read into the storage attach function, dump the
data and confirm that it looks right. Enable USB debugging and confirm
3.0 devices get enumerated at SuperSpeed (mostly).

24a53dddb9 ipq806x: clean up UART driver tx_byte function
The driver as it was copied from u-boot provided a function to
transmit multiple characters in one invocation. This feature was not
ported to coreboot, there is no need to maintain the complexity when
only one character at a time is transmitted. It is also very desirable
to get rid of a 1024 byte array allocated on the stack.

The array was necessary to allow to convert multiple newline
characters in the transmit data flow into two character sequences
CRLF. Now just a single word is enough to keep one or two characters
to transmit.

[EDIT km: newline translation is now part of printk]

BUG=chrome-os-partner:27784
TEST=verified that coreboot with the new code prints generates console
     output.

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.

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.

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.

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.

These patch modifies .h files to match the coreboot API. A few more
significant changes are:

 - UART specific fields removed from common board structure in cdp.h.
   These fields are set at compile time in u-boot (where this
   structure comes from), they will be set in a different structure in
   the UART driver in an upcoming patch.

 - an inline wrapper is added in gpio.h to provide GPIO API the UART
   driver expects.

 - the ipq_configure_gpio() is passed the descriptor placed in ro data.

0b341b341d ipq/arm: Redesign hooks for bootblock
The following patches had to be squashed
to properly build all the different ARM boards.

ipq8064: storm: re-arrange bootblock initialization

The recent addition of the storm bootblock initialization broke
compilation of Exynos platforms. The SOC specific code needs to be
kept in the respective source files, not in the common CPU code.

As of now coreboot does not provide a separate SOC initialization API.
In general it makes sense to invoke SOC initialization from the board
initialization code, as the board knows what SOC it is running on.

Presently all what's need initialization on 8064 is the timer. This
patch adds the SOC initialization framework for 8064 and moves there
the related code.

BUG=chrome-os-partner:27784
TEST=manual
  . nyan_big, peach_pit, and storm targets build fine now.

arm: Redesign mainboard and SoC hooks for bootblock

This patch makes some slight changes to the way bootblock_cpu_init() and
bootblock_mainboard_init() are used on ARM. Experience has shown that
nearly every board needs either one or both of these hooks, so having
explicit Kconfigs for them has become unwieldy. Instead, this patch
implements them as a weak symbol that can be overridden by mainboard/SoC
code, as the more recent arm64_soc_init() is also doing.

Since the whole concept of a single "CPU" on ARM systems has kinda died
out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had
already been done on Storm/ipq806x, which is now adjusted to directly
use the generic hook.) Also add a proper license header to
bootblock_common.h that was somehow missing.

Leaving non-ARM32 architectures out for now, since they are still using
the really old and weird x86 model of directly including a file. These
architectures should also eventually be aligned with the cleaner ARM32
model as they mature.

BRANCH=None
BUG=chrome-os-partner:32123
TEST=Booted on Pinky. Compiled for Storm and confirmed in the
disassembly that bootblock_soc_init() is still compiled in and called
right before the (now no-op) bootblock_mainboard_init().
