The function to disable devices was formerly named
pch_hide_devfn(). This routine was doing more than hiding
devices. It was disabling them, i.e. turning them off.
Therefore, rename it to pch_disable_devfn(). Also, allow

Now that there is a clearly defined boot state machine
we can add some useful post codes to indicate the current
point in the state machine by having it log a post code
before the execution of each state.
This removes the currently defined POST codes that were
used by hardwaremain in favor of a new contiguous range
that are defined for each boot state.
The reason for this is that the existing codes are mostly
used to indicate when something is done, which is confusing
for actual debug because POST code debugging relies on knowing
what is about to happen (to know what may be at fault) rather
than what has just finished.
One additonal change is added during device init step as this
step often does the bulk of the work, and frequently logs POST
codes itself. Therefore in order to keep better track of what
device is being initialized POST_BS_DEV_INIT is logged before
each device is initialized.

One of the most common hangs during coreboot execution
is during ramstage device init steps. Currently there
are a set of (somewhat misleading) post codes during this
phase which give some indication as to where execution
stopped, but it provides no information on what device
was actually being initialized at that point.
This uses the new CMOS "extra" log banks to store the
encoded device path of the device that is about to be
touched by coreboot. This way if the system hangs when
talking to the device there will be some indication where
to investigate next.

Mass storage devices such as card readers show up as

situations the previous code would just fake a disk and
call usbcreate_disk. This is inappropriate because it forms
a 1:1 mapping of USB device to disk leading to the inability
to remove the disk and/or handle "hot plug" card insertion
and removals.
To alleviate this issue introduce the notion of ready to the
usbmsc structure. It tracks detached, not ready, and ready
states. The polling routine is then used to track not ready
to ready transitions thereby creating and removing disks
appropriately. This handles the case of inserting and removing
a card that shows up as a new disk.

There is currently a hard-coded 30 sec delay in the mass storage
driver while waiting for each device to become ready. However, mass
storage card readers that are empty return an error code on the
TEST UNIT READY command. A REQUEST SENSE command then needs to be
issued and interrogate the data to determine if no media is present.
If no media determination is found to be true the USB device is no
longer considered a candidate to be a disk.
This code does lead to the fact that the media card reader needs to be
populated at enumeration time. I suspect this is not an issue as it
appears the storage stack in libpayload can't handle removable media
coming online later.
Booted recovery and dev modes. Noted that removable mass storage

When an INIT# is delivered to the CPU the CPU starts
executing from the reset vector. However, the internal state
is maintained. Therefore, check for such a condition and
reset the system.
Issues 'apreset warm' on the EC console. INIT# is sent and
CPU notices it's not a clean reset and forces one. No hangs.

The haswell i915 kernel driver apparently expects the VBIOS
to set a few specific registers. This sequence is enough to
make the driver happy without executing the VBIOS.
This also makes graphics work after suspend/resume.

Add the onboard I2C devices for Falco trackpad/lightsensor
and generate SMBIOS Type41 tables for them.
Add ACPI device for the trackpad to expose the interrupt map
to the OS so it can be used.
Configure interrupt GPIOs as PIRQ type and wake GPIOs as
just standard input type. The wake GPIO is reconfigured as
ACPI SCI in the specific device _DSW method. This prevents
the wake GPIO from generating a flood of SCI at runtime.
LTE_WAKE_L_Q and WLAN_WAKE_L_Q are left as ACPI SCI as these
are not repurposed interrupt pins so they are not generated
at runtime.
SIM_DET and ALS_INT_L are set as input since we don't have an
interrupt handler for them.

tested on slippy with trackpad with additional
kernel changes to chromeos_laptop.c to initialize devices.
1) Ensure trackpad interrupt is functional and that there
is not a flood of ACPI SCI when trackpad does interrupt:
9: 1 0 0 0 IO-APIC-fasteoi acpi
37: 421 0 0 0 IO-APIC-fasteoi cyapa
2) Ensure that devices are exposed as wake capable:
Device S-state Status Sysfs node
TPAD S3 *enabled pnp:00:00
TSCR S3 *disabled pnp:00:01
3) Ensure that trackpad can wake from S3 by default, but
that it does not cause an immediate wake when entering suspend.
4) Ensure that trackpad can be disabled as a wake source with
echo TPAD > /proc/acpi/wakeup

This is an LPT-LP specific method that will enable a specific
GPIO as an ACPI SCI wake source.
It can be used by a device _DSW method to enable a pin that is
otherwise not configured to generate SCI at runtime.
It will set:
- GPIO owner to ACPI
- GPIO route to SCI
- GPIO config to GPIO, Input, Inverted
Also clean up and remove ACPI field definitions that are unused
and/or incorrect.

In addition to not clearing the pending interrupts, we also
don't want to reset the RTC control register when booting
with an S3 resume.
On most new systems, when the RTC well is losing power, we
will also lose state that is required to perform a resume,
so we end up in a normal boot anyways. Hence don't do any
RTC initialization in the S3 resume path.

LynxPoint-LP has an additional 16 entries in the IOAPIC that
can be assigned to specific GPIOs when they are configured
as PIRQ.
The maximum redirection entries field in the IOAPIC needs to
be set to 0x27 when this is enabled.
Additionally specific GPIOs need to be routed to PIRQ so they
interrupt via the IOAPIC instead of the GPIO IRQ 14/15.
