The SPI controller operates on packets which can be variable
length up to 32-bit packets. It also has the ability to be
put in packed or unpacked mode w.r.t each packet. i.e. does
a single fifo register hold >= 1 packet. The current programming
uses 8-bit packets in unpacked mode which means 4 fifo slots
are used for a 32-bit DMA transfter. As the AHB can only operate
on a minimum of 32-bit bursts the triggers need to be programmed
correctly so that there is room for a full 32-bit DMA transaction.
Previously faster SPI clocks just made things magically work.

The Trust Zone carveout registers are only accessible using
a secure access mode. The AVP runs as non-secure all the time.
In EL3 the CPU is in secure mode, but when the MMU is enabled
the page tables dictate if accesses to certain regions are
secure or not. However, ramstage is currently being loaded
into non-secure memory and the page tables will live in
non-secure memory as well. Therefore, handle all these
cases by providing global state which mirrors the TZ
register.

BRANCH=None
TEST=Built and ran through ramstage with the MMU enabled
Resources are read and set accordingly.

The address map code was originally assuming all carveouts would
be packed together in the upper end of the physical memory
address space. However, the trust zone carveout is always in the
32-bit address space. Therefore, one needs to query memory ranges
by above and below 4GiB with the assumption of carveouts being
packed at the top of *each* resulting range.

We suspect that the code was stuck on init pllx (PLLX - acts as a clock source
for the CPU cluster). So, remove the init call for pllx. This needs to be added
later when required. Also, add a few more printks to display the progress.

This patch is to perform software triggered RAM re-repair in
the warm boot path.
"RAM" actually refers to the CPU cache here (yeah, I know, but that's
how the manuals call it). This is some magic hardware thing that must be
done every time after applying power to the main CPU cores or their
cache may have random failures in some very rare cases.
Also, note that this file isn't built in coreboot proper, but is a
companion binary for kernel. It resides here for safe keeping.

This reverts the revert commit 5780d6f3876723b94fbe3653c9d87dad6330862e
and fixes the build issue that cuased it to be reverted.
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_.

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.

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 serves as supplemental patch to CL:197732. After clearing bus, we
should also redo controller init (because controller has been reset
before bus clear). On the upper layer, upon receiving error return status,
it should just retry instead of simply call cpu_reset().

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.

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.

This is a fix for the 'Lost arb' we're seeing on Nyan* during
reboot stress testing. It occurs when we are slamming the
default PMIC registers with pmic_write_reg().
Currently, I've only captured this a few times, and the bus
clear seemed to work, as the PMIC writes continued (where
they'd hang the system before bus clear) for a couple of regs,
then it hangs hard, no messages, no 2nd lost arb, etc. So
I've added code to the PMIC write function that will reset the
SoC if any I2C error occurs. That seems to recover OK, i.e. on
the next reboot the PMIC writes all go thru, boot is OK, kernel
loads, etc.

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.

To ensure that the command1 write which sets the "go" bit completes before
other reads to the device. Otherwise, there's a race condition where those
register values might still have their values from the last transfer. With
different SPI clock frequencies, that could lead to spi_delay being told there
were negative bytes still to send. Its expected delay would wrap to a negative
value, that was passed to udelay, and the system would sit there for 4 seconds
not doing anything.

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.

The SPI drivers for tegra and exynos5420 have code in them which waits for a
frame header and leaves filler data out. The SPI driver shouldn't have support
for frame headers directly. If a device uses them, it should support them
itself. That makes the SPI drivers simpler and easier to write.
When moving the frame handling logic into the EC support code, EC communication
continued to work on tegra but no longer worked on exynos5420. That suggested
the SPI driver on the 5420 wasn't working correctly, so I replaced that with
the implementation in depthcharge. Unfortunately that implementation doesn't
support waiting for a frame header for the EC, so these changes are combined
into one.

This patch changes the ENTRY() macro in asm.h to create a new section
for every assembler function, thus providing dcache_clean/invalidate_all
and friends with the same --gc-sections goodness that our C functions
have. This requires a few minor changes of moving around data (to make
sure it ends up in the right section) and changing some libgcc functions
(which apparently need to have two names?), but nothing serious.
(You may note that some of our assembly functions have data, sometimes
even writable, within the same .text section. This has been this way
before and I'm not looking to change it for now, although it's not
totally clean. Since we don't enforce read-only sections through paging,
it doesn't really hurt.)
BUG=None

The divider for the I2C clocks works differently than for other IP blocks and
needs to be set up to reflect that. There's also a large internal divider which
means you have to do extra calculations to determine what the frequency of the

desired frequency of the bus itself and figures everything else out.

back to ARM until the final assembly stub that jumps to the kernel.
The required changes to make this work include some new headers and
Makefile flags to handle assembly files (using the unified syntax and
the same helper macros as Linux), modifying our custom-written libgcc
code for 64-bit division to support Thumb (removing some stale old files
that were never really used for clarity), and flipping the general
CFLAGS to Thumb (some more cleanup there as well while I'm at it).
BUG=None
TEST=Snow and Nyan still boot.
