Calling the various Print functions picked up some warnings in my
project (using GCC 4.8 and 4.9 at the moment):
warning: passing argument 1 of Print discards const qualifier from

c108e118da Add support for PCI Root Bridge I/O protocol.
PCI Root Bridge I/O protocol is used by PCI Bus Driver to perform
PCI Memory, PCI I/O, and PCI Configuration cycles on a
PCI Root Bridge. It also provides services to perform different
types of bus mastering DMA.

V2 - Scratch that - there already exists an efipciio.h with most
of these definitions. Let me remove this patch and propose a new
one that will amend what's already there.
OK, here's a better version that adds the required definition in
efipciio.h. Note that EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL and
EFI_PCI_IO_PROTOCOL are two different protocols.

V3 - Pete, There are now two defines of EFI_PCI_ADDRESS.
Please repost with your define removed.
Nigel, Sorry about that. Here's v3.

751cbce3f6 Update global protocol GUIDs definitions to match EDK2
This patch introduces the use of the EDK2 names for the global GUID
variables, to allow for easier code conversion between EDK2 and
gnu-efi. All the existing GUID global variables have also been
aliased for backwards compatibility.

The patch also completes some of the earlier work with regards to
protocol struct definitions to also match the EDK2, with the
following caveat:
Because some of gnu-efi GUID macro definitions were declared with
the name that the EDK2 uses for the protocol struct itself, we have
to immediately deprecate the following GUID data aliases:
EFI_NETWORK_INTERFACE_IDENTIFIER_PROTOCOL
EFI_SIMPLE_NETWORK_PROTOCOL
EFI_PCI_IO_PROTOCOL
EFI_PXE_BASE_CODE_CALLBACK_PROTOCOL
This means that existing code using one of the above will break
on compilation. To mitigate this, explicit warnings have been
placed at the location where a developer will look for breakage,
detailing how they should amend their code.

The KnownGuids short labels in guid.c were also updated/amended
in a manner that should be a bit more consistent (though I have
no idea what the EDK2 does here, since I haven't looked at the
actual EDK2 source).

Finally, besides clean up (typo, whitespaces, duplicate removal),
we introduce the _GNU_EFI macro, in efi.h, to allow for conditional
selection of specific gnu-efi API calls, in code that may be
compiled with either EDK2 or gnu-efi.

1b10394e06 This patch is a follow up to 8118d08727
and completes the renaming of structs, defines, and typedefs to match
the naming convention from the latest UEFI specifications.

This should make it easier for people to switch between EDK2 and
gnu-efi compilation.

The original names are #defined or typedef'd to the new names for
backwards compatibility. Also some whitespace cleanup was applied.

Note 1: From what I could see of the EDK API documentation,
structs are being aliased to their old names using typedef rather
than #define, so that's what I used. I altered some of the #define
from 8118d0 accordingly

Note 2: I also think it might be more helpful for users to keep
the backwards compatibility defs close to their declaration
(e.g. old GUID def right after current GUID declaration), rather
than in a separate section as was done in 8118d0, so that's what
I did in this patch.

b2c4db065f I did a quick review of the MS x86_64 calling convention for floating
point and as far as I can tell it agrees with the UEFI spec.
The attached patch removes -mno-mmx and -mno-sse for x86_64 and adds
a new Print target, "%f", to print float and double types.

It seems to compile for ia32, although I'm not sure why - shouldn't
it be throwing errors because the new function FloatToStr() in print.c
accepts a float, yet I left -no-sse for ARCH=ia32? A better solution
might be to add -msoft-float for targets where the floating point
calling convention doesn't match the UEFI spec. As I'm not familiar
with UEFI on ia32, I didn't make any changes to it.

8118d08727 Protocol struct/type/define renaming to match spec naming convention.
This patch renames a number of structs, defines, and typedefs to match
the naming convention in the UEFI specification. For example, it renames
DRIVER_BINDING_PROTOCOL (preprocessor GUID define) to
EFI_DRIVER_BINDING_PROTOCOL_GUID, and renames EFI_DRIVER_BINDING (protocol
interface) to EFI_DRIVER_BINDING_PROTOCOL.

The original names are all #defined to the new names for backwards
compatibility, so nothing should be broken.

Included in this patch are renames for all the types/defines for the
following protocols:
EFI_DRIVER_BINDING_PROTOCOL
EFI_COMPONENT_NAME_PROTOCOL
EFI_COMPONENT_NAME2_PROTOCOL
EFI_LOADED_IMAGE_PROTOCOL

If you accept this patch I'll work on adjusting all the other protocols
to match the spec as well, as time allows. Moving to the spec's naming
convention makes the code clearer and improves portability with EDK2.

5ff74ecae8 Commit 3dd05c and subsequent ones introduced the use of the GNU
specific __attribute__((__unused__)), which breaks MSVC compilation...

I'll use this as a reminder that gnu-efi is compiled with more than
GNU toolchains, and that contributors might want to be careful about
adding GNU-specific extensions...

This patch does the following:
Create a new eficompiler.h header that sets all compiler-specific
options and extensions
Create a new EFI_UNUSED macro to be used in lieu of
__attribute__((__unused__)) and applies it to the relevant sources
Move the ALIGN(x) macro, previously defined in efisetjmp.h to the new header

Oh, and it also fixes a bunch of trailing whitespaces (because my code
editor is set to do just that by default).

dae0b4b0b0 Turns out we actually need setjmp in one of gnu-efi's prominent
users, and it seems to make more sense to put it here than in
the application.

All of these are derived from the Tiano code, but I re-wrote the
x86_64 one because we use the ELF psABI calling conventions instead
of the MS ABI calling conventions.  Which is to say you probably
shouldn't setjmp()/longjmp() between functions with EFIAPI (aka
__attribute__((ms_abi))) and those without.

ce7098fb52 Enable out-of-tree building
This patch enables building gnu-efi outside of the source tree.
That in turn enables building for multiple architectures in parallel.

The build directory is controlled by the OBJDIR make variable.  It
defaults to the value of ARCH, and can be overridden from the command
line.

This patch also cleans up some doubled slashes between INSTALLROOT
