Provide a single instance of EFI_DRIVER_BINDING_PROTOCOL (attached to
our image handle); this matches the expectations scattered throughout
the EFI specification.
Open the underlying hardware device using EFI_OPEN_PROTOCOL_BY_DRIVER
and EFI_OPEN_PROTOCOL_EXCLUSIVE, to prevent other drivers from
attaching to the same device.
Do not automatically connect to devices when being loaded as a driver;
leave this task to the platform firmware (or to the user, if loading
directly from the EFI shell).
When running as an application, forcibly disconnect any existing
drivers from devices that we want to control, and reconnect them on
exit.
Provide a meaningful driver version number (based on the build
timestamp), to allow platform firmware to automatically load newer
versions of iPXE drivers if multiple drivers are present.
Include device paths within debug messages where possible, to aid in
debugging.

Some UEFI builds will set up a timer to continuously poll any SNP
devices. This can drain packets from the network device's receive
queue before iPXE gets a chance to process them.
Use netdev_rx_[un]freeze() to explicitly indicate when we expect our
network devices to be driven via the external SNP API (as we do with
the UNDI API on the standard BIOS build), and disable the SNP API
except when receive queue processing is frozen.

Exploit the redefinition of iPXE error codes to include a "platform
error code" to allow for meaningful conversion of EFI_STATUS values to
iPXE errors and vice versa.

Abstract out the ability to reboot the system to a separate reboot()
function (with platform-specific implementations), add an EFI
implementation, and make the existing "reboot" command available under
EFI.

When iPXE is used as a UEFI driver, the UEFI PXE base code currently
provides the TCP/IP stack, network protocols, and user interface.
This represents a substantial downgrade from the standard BIOS iPXE
user experience.
Fix by installing our own EFI_LOAD_FILE_PROTOCOL implementation which
initiates the standard iPXE boot procedure. This upgrades the UEFI
iPXE user experience to match the standard BIOS iPXE user experience.

Expose iPXE's images as a UEFI file system, allowing the booted image
to access all images downloaded by iPXE.
This functionality is complementary to the custom iPXE download
protocol. The iPXE download protocol allows a booted image to utilise
iPXE to download arbitrary URIs, but requires the booted image to
specifically support the custom iPXE download protocol. The new
functionality limits the booted image to accessing only files that
were already downloaded by iPXE (e.g. as part of a script), but can
work with any generic UEFI image (e.g. the UEFI shell). Both
protocols are provided simultaneously, and are attached to the SNP
device handle.

The script include/ipxe/efi/import.pl relies on a particular format
for the #include guard in order to detect EFI headers that are not
imported.

iPXE exposes some extended capabilities via the PXE FILE API to allow
NBPs such as pxelinux to use protocols other than TFTP. Provide an
equivalent interface as a UEFI protocol so that EFI binaries may also
take advantage of iPXE's extended capabilities.
This can be used with a patched version of elilo, for example:

Re-open the EFI_PCI_IO_PROTOCOL specifying an Attributes value of
EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER. This causes the SNP devices to
be marked as children of the EFI PCI device (as shown in the "devtree"
command).
On at least one IBM blade system, this is required in order to have
the relevant drivers automatically attach to the SNP controller at
device creation time.

Commit d7736fb ("[efi] Allow EFI to control PCI bus enumeration")
introduced a bug in which the EFI driver name became an
(uninitialised) pointer rather than an array.

EFI performs its own PCI bus enumeration. Respect this, and start
controlling devices only when instructed to do so by EFI.
As a side benefit, we should now correctly create multiple SNP
instances for multi-port devices.
This should also fix the problem of failing to enumerate devices
because the PCI bridges have not yet been enabled at the time the iPXE
driver is loaded.

Add a new network driver that consumes the EFI Simple Network
Protocol. Also add a bus driver that can find the Simple Network
Protocol that iPXE was loaded from; the resulting behavior is similar
to the "undionly" driver for BIOS systems.

Access to the gpxe.org and etherboot.org domains and associated

around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.
