Aaron Durbin bef75e7dd9 soc/intel/apollolake: add support for verstage
There previously was no support for building verstage on apollolake.
Add that suport by linking in the appropriate modules as well as
providing vboot_platform_is_resuming(). The link address for verstage
is the same as FSP-M because they would never be in CAR along side
each other. Additionally, program the ACPI I/O BAR and enable decoding
so sleep state can be determined for early firmware verification.

Alexandru Gagniuc c4ea8f7d3f drivers/intel/fsp2_0: Send post codes around calls to the blobs
By design, FSP will send POST codes to port 80. In this case we have
both coreboot and FSP pushing post codes, which may make debugging
harder. In order to get a clear picture of where FSP execution begins
and ends, send post codes before and after any call to the FSP blobs.

Note that sending a post code both before and after is mostly useful
on chromeec enabled boards, where the EC console will provide a
historic list of post codes.

The current code was using !__PRE_RAM__ as a proxy for ramstage
conditional compilation. In the face of postcar stage not defining
__PRE_RAM__ (because it's after RAM is up) these code paths
can fail to compile with a __SIMPLE_DEVICE__ defined for the entire
stage. Remedy the current situation by just compiling explicity for
ramstage because that was the original intent. In the future,
the __SIMPLE_DEVICE__ selection for postcar can also be re-evaluated.

and it's optionally employed.

Duncan Laurie 3a39f44fc4 gpio: Add a function to map GPIO to ACPI path
Add a new function "gpio_acpi_path()" that can be implemented by
SoC/board code to provide a mapping from a "gpio_t" pin to a
controller by returning the ACPI path for the controller that owns
this particular GPIO.

This is implemented separately from the "acpi_name" handler as many
SOCs do not have a specific device that handles GPIOs (or may have
many devices and the only way to know which is the opaque gpio_t)
and the current GPIO library does not have any association with the
device tree.

If not implemented (many SoCs do not implement the GPIO library
abstraction at all in coreboot) then the default handler will return
NULL and the caller knows it cannot determine this reliably.

Duncan Laurie 2f6fb9f5f9 skylake: Add ACPI device name handler
Add a global ACPI device name handler for the Skylake SOC that will
translate skylake device paths into an ACPI path that matches the
device objects delcared in the DSDT at soc/intel/skylake/acpi/*.

The skylake implementation uses a global acpi_name handler for the
SOC and it is not necessary to add a function to every device.

This function is used by device drivers calling acpi_device_name()
and acpi_device_path() to generate ACPI AML in the SSDT.

Duncan Laurie d9af3cecae device: Add an ACPI device name and path concept to devices
Add a function to "struct device_operations" to return the ACPI name
for the device, and helper functions to find this name (either from
the device or its parent) and to build a fully qualified ACPI path
from the root device.

This addition will allow device drivers to generate their ACPI AML in
the SSDT at boot, with customization supplied by devicetree.cb,
instead of needing custom DSDT ASL for every mainboard.

The root device acpi_name is defined as "\\_SB" and is used to start
the path when building a fully qualified name.

This requires SOC support to provide handlers for returning the ACPI
name for devices that it owns, and those names must match the objects
declared in the DSDT.  The handler can be done either in each device
driver or with a global handler for the entire SOC.

Simplified example of how this can be used for an i2c device declared
in devicetree.cb with:

  chip soc/intel/skylake          # "\_SB" (from root device)
    device domain 0 on            # "PCI0"
      device pci 19.2 on          # "I2C4"
        chip drivers/i2c/test0
          device i2c 1a.0 on end  # "TST0"
        end
      end
    end
  end

And basic SSDT generating code in the device driver:

  acpigen_write_scope(acpi_device_scope(dev));
  acpigen_write_device(acpi_device_name(dev));
  acpigen_write_string("_HID", "TEST0000");
  acpigen_write_byte("_UID", 0);
  acpigen_pop_len(); /* device */
  acpigen_pop_len(); /* scope */

Will produce this ACPI code:

  Scope (\_SB.PCI0.I2C4) {
    Device (TST0) {
      Name (_HID, "TEST0000")
      Name (_UID, 0)
    }
  }

acpigen_write_uuid() will generate a ToUUID() 128-bit buffer object for a

Alexandru Gagniuc 63e7b5b8a7 lib/timestamp: Do not initialize cache in timestamp_cache_get()
timestamp_cache_get() would call timestamp_cache_init() whenever it
found a timestamp cache in the TIMESTAMP_CACHE_UNINITIALIZED state.
That means that timestamp_cache_get() will never reurn a cache in the
uninitialized state.

However, timestamp_init() checks against the uninitialized state, as
it does not expect timestamp_cache_get() to perform any initialization.
As a result, the conditional branch can never be reached.

Simply remove the timestamp_cache_init() call from timestamp_cache_get().

Alexandru Gagniuc 87c6097c8f arch/x86: Include timestamp.c in all stages
timestamp.c was not included in bootblock and postcar. This means that
these two stages would use the weak implementation in lib/timestamp.c
instead of the arch-specific implementation based on rdtsc.

This resulted in using timer_monotonic_get() which resets the
timestamps from 0. timer_monotonic_get() only provides per-stage
incrementing semantics on x86 because lapic implementation has
counting down values. A globally incrementing counter like rdtsc
provides the semantics like every other non-x86.

On the test configuration, the weak implementation of timestamp_get()
returned zero, resulting in wrong timestamps coming from the bootblock,
while romstage and ramstage used the arch implementation and returned
correct timestamps.

This is a great example of why weak functions are dangerous, and how
easy it is to miss subtle yet strong interactions between subsystems
and the coreboot buildsystem.
