92b0e8dcae drivers/generic/cbfs-serial: Add driver to read serial from CBFS
Add a new driver to support reading a board serial number from
a text file in CBFS and injecting into the SMBIOS tables.
Allow driver to be selected at the .config level and not require
inclusion at the board level.

540a98001d printf: Automatically prefix %p with 0x
According to the POSIX standard, %p is supposed to print a pointer "as
if by %#x", meaning the "0x" prefix should automatically be prepended.
All other implementations out there (glibc, Linux, even libpayload) do
this, so we should make coreboot match. This patch changes vtxprintf()
accordingly and removes any explicit instances of "0x%p" from existing
format strings.

How to handle zero padding is less clear: the official POSIX definition
above technically says there should be no automatic zero padding, but in
practice most other implementations seem to do it and I assume most
programmers would prefer it. The way chosen here is to always zero-pad
to 32 bits, even on a 64-bit system. The rationale for this is that even
on 64-bit systems, coreboot always avoids using any memory above 4GB for
itself, so in practice all pointers should fit in that range and padding
everything to 64 bits would just hurt readability. Padding it this way
also helps pointers that do exceed 4GB (e.g. prints from MMU config on
some arm64 systems) stand out better from the others.

c135b829e7 drivers/gfx: Add generic graphics with SSDT generator
Adds a generic graphics driver that can be added to a devicetree which
populates graphics-related ACPI table. It will write the _DOD method
(Enumerate All Devices Attached to the Display Adapter) and a device
object for each device defined. The device may optionally have a
connected privacy screen which can be controlled with a _DSM.

Example:
chip drivers/generic/gfx
  register "device_count" = "1"
  register "device[0].name" = ""LCD""
  register "device[0].addr" = "0x0400"
  register "device[0].privacy.enabled" = "1"
  register "device[0].privacy.detect_function" = ""\\_SB.PCI0.PVSC.GPVD""
  register "device[0].privacy.status_function" = ""\\_SB.PCI0.PVSC.GPVX""
  register "device[0].privacy.enable_function" = ""\\_SB.PCI0.PVSC.EPVX""
  register "device[0].privacy.disable_function" = ""\\_SB.PCI0.PVSC.DPVX""
  device generic 0 on end

08c76e1f7d devicetree: Fix improper use of chip_operations
Auto-discoverable PCI devices do not require field .enable_dev
of chip_operations to be set. They are matched with PCI drivers
by the use of PCI vendor and device ID fields.

The name given for the chip_operations struct must match the
pathname the way it is present in the devicetree.cb files. If
there was no match, util/sconfig would currently choose to
use the empty weak declaration it creates in static.c file.

ffc9990ece acpi: Change device properties to work as a tree
There is a second ACPI _DSD document from the UEFI Forum that details
how _DSD style tables can be nested, creating a tree of similarly
formatted tables.  This document is linked from acpi_device.h.

In order to support this the device property interface needs to be
more flexible and build up a tree of properties to write all entries
at once instead of writing each entry as it is generated.

In the end this is a more flexible solution that can support drivers
that need child tables like the DA7219 codec, while only requiring
minor changes to the existing drivers that use the device property
interface.

This was tested on reef (apollolake) and chell (skylake) boards to
ensure that there was no change in the generated SSDT AML.

366cd21472 drivers/generic/max98357a: Fix naming and ACPI path handling
The upstream kernel driver is not using the of-style naming for
sdmode-gpio so remove the maxim prefix, and remove the duplicate
entry for the sdmode-delay value as well.

Also fix the usage of the path variable, since the device path uses
a static variable it can't be assigned that early or it will be
overwritten by later calls.

This results in the following output for the _DSD when tested on
reef mainboard:

Name (_DSD, Package (0x02)
{
    ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301")

7db15094c2 generic: Add a Maxim 98357A codec driver
The Maxim Integrated 98357A codec is an I2S slave device that has no
control channel for configuration and instead provides a GPIO that is
used for channel selection and power down.  This means it does not fit
into a bus hierarchy easily and is instead represented as a generic
device and found with a static bus scan using the devicetree.

This driver provides configuration options for passing the "sdmode" GPIO
descriptor as well as a second option for "sdmode delay" which can
configure the timing of the sdmode toggling in relation to the I2S
channel output.

In addition an GPIO can be provided to indicate to the driver whether
this device is present or not.  This can be used for board designs that
may have different codec possibilities that are selected by HW strap.

Sample usage for this device driver:

device pci 1f.3 on
  chip drivers/generic/max98357a
    register "sdmode_gpio" = "ACPI_GPIO_OUTPUT(GPP_C6)"
    register "sdmode_delay" = "100"
    device generic 0 on end
  end
end

Will result in the following code in the SSDT:

Scope (\_SB.PCI0.HDAS) {
  Device (MAXM) {
    Name (_HID, "MX98357A")
    Name (_UID, Zero)
    Name (_DDN, "Maxim Integrated 98357A Amplifier")
    Method (_STA) { Return (0xF) }
    Name (_CRS, ResourceTemplate () {
      GpioIo (Exclusive, PullDefault, 0, 0, IoRestrictionOutputOnly,
              "\\_SB.PCI0.GPIO", 0, ResourceConsumer)
    })
    Name (_DSD, Package () {
      ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
      Package () {
        Package () { "maxim,sdmode-gpio", \_SB.PCI0.HDAS.MAXM, 0, 0, 0 }
        Package () { "maxim,sdmode-delay", 100 }

      }

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

ac75bc682b x86 I/O APIC: Make functions io_apic_{read,write}() public
Some LPC initialiation can save some lines of code when being able
to use the functions `io_apic_read()` and `io_apic_write()`.

As these two functions are now public, remove them from the generic
driver as otherwise we get a build errors like the following.

In the file `COPYING` in the coreboot repository and upstream [1]
just one space is used.

The following command was used to convert all files.

    $ git grep -l 'MA  02' | xargs sed -i 's/MA  02/MA 02/'

23f38cd05c Get rid of drivers class
The use of ramstage.a required the build system to handle some
object files in a special way, which were put in the drivers
class.

These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.

With ramstage.a gone, we can drop this special class, too.
