Enabling sync flood on DRAM MCE directly after ECC clear can
lead to a system hang with no way to determine the offending
DRAM module. Clear MCEs after ECC setup, but do not enable
sync flood until NB setup in ramstage to allow time for any
MCEs to accumulate in the status registers. Before enabling
sync flood on MCE, determine if any MCEs were logged during
ramstage execution and display them on the serial console.
Also clear the DRAM ECC sync flood bits during DRAM training
and initial ramstage execution.

DRAM initialization on storm requires ipq blobs to be

Since cbmem_find calls into cbmem_top to identify the location of
cbmem area, board/chipset is expected to return NULL until the backing
store is ready, which in this case until DRAM is initialized in
romstage, return NULL for cbmem_top.

A call to i2c_read() for a non-existent address followed by an i2c_read()
to a valid address results in a false abort status for the 2nd call.

i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0x4000000 (I2C_ERR_ABORT)
Because the abort status register is cleared on read and wait_tx_fifo()
reads it twice, the returned status does not contain the abort status.
Fixing that changed the 2nd read to reflect the abort status.
i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT)
i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0x4000001 (I2C_ERR_ABORT)
Bit 0 indicates that the address was not acknowledged by any slave.
That's the abort status from the previous transaction.
So I added a read of the abort status before starting a transaction in
both i2c_read() and i2c_write().
i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT)

Coreboot and most payloads support three basic pixel widths for the
framebuffer. It assumes 32 by default, but several chipsets need to
override that value with whatever else they're supporting. Our struct
edid contains multiple convenience values that are directly derived from
this (and other properties), so changing the bits per pixel always
requires recalculating all those dependents in the chipset code. This
patch provides a small convenience wrapper that can be used to
consistently update the whole struct edid with a new pixel width
instead, so we no longer need to duplicate those calculations
everywhere.
BUG=None
TEST=Booted Oak in all three pixel widths (which it conveniently all

The current Apollolake flow has its code executing out of
cache-as-ram for the pre-DRAM stages. This is different from
past platforms where they were just executing-in-place against
the memory-mapped SPI flash boot media. The implication is
that when cache-as-ram needs to be torn down one needs to be
executing out of DRAM since the act of cache-as-ram going
away means the code disappears out from under the processor.
Therefore load and use the postcar infrastructure to bootstrap
this process for tearing down cache-as-ram and subsequently
loading ramstage.

Certain chipsets don't have a memory-mapped boot media
so their code execution for stages prior to DRAM initialization
is backed by SRAM or cache-as-ram. The postcar stage/phase
handles the cache-as-ram situation where in order to tear down
cache-as-ram one needs to be executing out of a backing
store that isn't transient. By current definition, cache-as-ram
is volatile and tearing it down leads to its contents disappearing.
Therefore provide a shim layer, postcar, that's loaded into
memory and executed which does 2 things:
1. Tears down cache-as-ram with a chipset helper function.
2. Loads and runs ramstage.
Because those 2 things are executed out of ram there's no issue
of the code's backing store while executing the code that
tears down cache-as-ram. The current implementation makes no
assumption regarding cacheability of the DRAM itself. If the
chipset code wishes to cache DRAM for loading of the postcar
stage/phase then it's also up to the chipset to handle any
coherency issues pertaining to cache-as-ram destruction.

This patch adds support for an alternative ternary number system in
which group of GPIOs can be interpreted. In this system, the digit
combinations that would form a binary number (i.e. that contain no 'Z'
state) are used to represent the lower values in the way they're used in
the normal binary system, and all the combinations that do contain a 'Z'
are used to represent values above those. We can use this for boards
that originally get strapped with binary board IDs but eventually
require more revisions than that representation allows. We can switch
their code to binary_first base3 and all old revisions with already
produced boards will still get read as the correct numbers.
Credit for the algorithm idea goes to Haran Talmon.
BRANCH=None
BUG=None
TEST=Stubbed out the actual GPIO reading and simulated all combinations
of 4 ternary digits for both number systems.

Set MMCONF_BASE_ADDRESS to 0xf8000000.
It was already done for some boards, but not all.
The sandybridge chipset code assumes 64 pci buses behind MMCONF.
Therefore, only 64MiB of physical address space is required.
Increasing the address allows to use additional 128MiB of MMIO
space and to use the Intel IGD and a PEG at the same time.
Previously it wasn't possible to use both at the same time,
as two 256MiB areas won't fit into MMIO space.
Test system:
* Gigabyte GA-B75M-D3H
* Intel Pentium CPU G2130
* Onboard GPU Intel IvyBridge Desktop
* PEG GPU AMD RV770

In Chromium OS downstream this was done together with adding the support
for ATF, but unfortunately ATF upstream isn't ready yet. This commit
is a reminder to enable things once ATF caught up.
