The EFI_CPU_IO_PROTOCOL is not available on all EFI platforms. In
particular, it is not available under OVMF, as used for qemu.
Since the EFI_CPU_IO_PROTOCOL is an abomination of unnecessary
complexity, banish it and use raw I/O instead.

The WinCE, a.out and FreeBSD loaders are designed to be #included by
core/loader.c, which no longer exists. These old loaders are not

Allow iPXE settings to be specified in the .vmx file via the VMware
GuestInfo mechanism. For example:
guestinfo.ipxe.filename = "http://boot.ipxe.org/demo/boot.php"
guestinfo.ipxe.dns = "192.168.0.1"
guestinfo.ipxe.net0.ip = "192.168.0.15"
guestinfo.ipxe.net0.netmask = "255.255.255.0"
guestinfo.ipxe.net0.gateway = "192.168.0.1"

iPXE's support for COMBOOT images is now quite outdated; it has not
kept up to date with changes in the COMBOOT API. The primary use for
COMBOOT seems to be for menuing support. Now that we have native iPXE
script-based menus, COMBOOT support can be gracefully retired (with
immense thanks to Daniel Verkamp for having successfully implemented
such an ambitious feature many years ago).

Allow iPXE scripts to create menus. For example:

item --default boot Boot from ${root-path}
item shell Enter iPXE shell
item exit Exit to BIOS
choose label && goto ${label}
:boot
sanboot ${root-path}
:install
sanhook ${root-path}
chain http://${next-server}/fedora.ipxe
:shell
shell
:exit

Provide an internal syslog() function (unrelated to the syslog
console) which can be used to create log messages with specified
priorities.
The build-time constant LOG_LEVEL can be used to select the minimum
required priority for log messages. Any messages that do not have a
sufficient priority will be ignored (and will be optimised away at
compile-time).
The default LOG_LEVEL is LOG_NONE.

The RTC-based entropy source uses the nanosecond-scale CPU TSC to
measure the time between two 1kHz interrupts generated by the CMOS
RTC. In a physical machine these clocks are driven from independent
crystals, resulting in some observable clock drift. In a virtual
machine, the CMOS RTC is typically emulated using host-OS
constructions such as SIGALRM.

ANS X9.82 specifies several Approved Sources of Entropy Input (SEI).
One such SEI uses an entropy source as the Source of Entropy Input,
condensing each entropy source output after each GetEntropy call.
This can be implemented relatively cheaply in iPXE and avoids the need
to allocate potentially very large buffers.
(Note that the terms "entropy source" and "Source of Entropy Input"
are not synonyms within the context of ANS X9.82.)
Use the iPXE API mechanism to allow entropy sources to be selected at
compilation time.

Several BIOSes (including most IBM BIOSes and many virtual machine
BIOSes) do not provide detectable PnP support, but will use the BEV
entry point for a PnP option ROM. On these semi-PnP BIOSes, iPXE will
respond to the absence of detectable PnP support by hooking INT19,
which disrupts the boot order.
BIOSes that genuinely require hooking INT19 seem to be very rare
nowadays. It may therefore be preferable to assume that the absence
of detectable PnP support indicates a semi-PnP BIOS rather than a
non-PnP BIOS.
Change the default behaviour so that INT19 will never be hooked unless
the compile-time option NONPNP_HOOK_INT19 is enabled. Leave the
redundant PnP detection routine in-place to allow for debugging via
the ROM banner line.

The block device interface used in gPXE predates the invention of even
the old gPXE data-transfer interface, let alone the current iPXE
generic asynchronous interface mechanism. Bring this old code up to
date, with the following benefits:
o Block device commands can be cancelled by the requestor. The INT 13
layer uses this to provide a global timeout on all INT 13 calls,
with the result that an unexpected passive failure mode (such as
an iSCSI target ACKing the request but never sending a response)
will lead to a timeout that gets reported back to the INT 13 user,
rather than simply freezing the system.
o INT 13,00 (reset drive) is now able to reset the underlying block
device. INT 13 users, such as DOS, that use INT 13,00 as a method
for error recovery now have a chance of recovering.
o All block device commands are tagged, with a numerical tag that
will show up in debugging output and in packet captures; this will
allow easier interpretation of bug reports that include both
sources of information.
o The extremely ugly hacks used to generate the boot firmware tables
have been eradicated and replaced with a generic acpi_describe()
method (exploiting the ability of iPXE interfaces to pass through
methods to an underlying interface). The ACPI tables are now
built in a shared data block within .bss16, rather than each
requiring dedicated space in .data16.
o The architecture-independent concept of a SAN device has been
exposed to the iPXE core through the sanboot API, which provides
calls to hook, unhook, boot, and describe SAN devices. This
allows for much more flexible usage patterns (such as hooking an
empty SAN device and then running an OS installer via TFTP).

Add user access API for linux.
On linux userspace virtual == user == phys addresses. Physical
addresses also being the same is wrong, but there is no general way of
converting userspace addresses to physical as what appears to be
contiguous in userspace is physically fragmented. Currently only the
DMA memory is special-cased, but its conversion to bus addresses is
done in phys_to_bus. This is known to break virtio as it is passing
phys addresses to the virtual device.

Setting NETDEV_DISCARD_RATE to a non-zero value will cause one in
every NETDEV_DISCARD_RATE packets to be discarded at random on both
the transmit and receive datapaths, allowing the robustness of
upper-layer network protocols to be tested even in simulation
environments that provide wholly reliable packet transmission.
