This reverts the parts of commit 3b3ea2c56ec4bc5588281fd103c744e608f8b25c
where it changed the EFI dependency on NET.

Not complete, but enough for Shell.efi and SCT.efi. We'll implement the
rest as needed or once we have SCT running properly so there is a way to
validate the interface against the conformance test suite.
Initial skeleton written by Leif, and then implementation by Rob.

Depending on your compiler, when compiling the hello world efi binary
with -Os, gcc might think it's a smart idea to replace common patterns
such as memory copies with explicit calls to memcpy().
While that sounds great at first, we don't have any memcpy() available
in our helloworld build target. So let's indicate to gcc that we really
do want to have the code be built as freestanding.

Similar to a "real" UEFI implementation, the bootmgr looks at the
BootOrder and BootXXXX variables to try to find an EFI payload to load
and boot. This is added as a sub-command of bootefi.
The idea is that the distro bootcmd would first try loading a payload
via the bootmgr, and then if that fails (ie. first boot or corrupted
EFI variables) it would fallback to loading bootaa64.efi. (Which
would then load fallback.efi which would look for \EFI\*\boot.csv and
populate BootOrder and BootXXXX based on what it found.)

Add EFI variable support, mapping to u-boot environment variables.
Variables are pretty important for setting up boot order, among other
things. If the board supports saveenv, then it will be called in
ExitBootServices() to persist variables set by the efi payload. (For
example, fallback.efi configuring BootOrder and BootXXXX load-option
variables.)
Variables are *not* currently exposed at runtime, post ExitBootServices.
On boards without a dedicated device for storage, which the loaded OS
is not trying to also use, this is rather tricky. One idea, at least
for boards that can persist RAM across reboot, is to keep a "journal"
of modified variables in RAM, and then turn halt into a reboot into
u-boot, plus store variables, plus halt. Whatever the solution, it
likely involves some per-board support.
Mapping between EFI variables and u-boot variables:
efi_$guid_$varname = {attributes}(type)value
For example:
efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_OsIndicationsSupported=
"{ro,boot,run}(blob)0000000000000000"
efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_BootOrder=
"(blob)00010000"
The attributes are a comma separated list of these possible
attributes:
+ ro - read-only
+ boot - boot-services access
+ run - runtime access
NOTE: with current implementation, no variables are available after
ExitBootServices, and all are persisted (if possible).
If not specified, the attributes default to "{boot}".
The required type is one of:
+ utf8 - raw utf8 string
+ blob - arbitrary length hex string

Helpers to construct device-paths from devices, partitions, files, and
for parsing and manipulating device-paths.
For non-legacy devices, this will use u-boot's device-model to construct
device-paths which include bus hierarchy to construct device-paths. For
legacy devices we still fake it, but slightly more convincingly.

Today we can compile a self-contained hello world efi test binary that
allows us to quickly verify whether the EFI loader framwork works.
We can use that binary outside of the self-contained test case though,
by providing it to a to-be-tested system via tftp.
This patch separates compilation of the helloworld.efi file from
including it in the u-boot binary for "bootefi hello". It also modifies
the efi_loader test case to enable travis to pick up the compiled file.
Because we're now no longer bloating the resulting u-boot binary, we
can enable compilation always, giving us good travis test coverage.

We can pass SMBIOS easily as EFI configuration table to an EFI payload. This
patch adds enablement for that case.
While at it, we also enable SMBIOS generation for ARM systems, since they support
EFI_LOADER.

We can now successfully boot EFI applications from disk, but users
may want to also run them from a PXE setup.
This patch implements rudimentary network support, allowing a payload
to send and receive network packets.
With this patch, I was able to successfully run grub2 with network
access inside of QEMU's -M xlnx-ep108.

The EFI standard defines a simple boot protocol that an EFI payload can use
to access video output.
This patch adds support to expose exactly that one (and the mode already in
use) as possible graphical configuration to an EFI payload.
With this, I can successfully run grub2 with graphical output.
