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.

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
and PREFIX.

* "lib\x86_64\math.c(49): error C4235: nonstandard extension used : '_asm' keyword not supported
on this architecture"
* "lib\print.c(98): error C2059: syntax error : '('" due to placement of EFIAPI macro
* "lib\cmdline.c(94): warning C4090: 'function' : different 'const' qualifiers"
* "lib\smbios.c(25): warning C4068: unknown pragma"
* Also update macro definitions in "inc\<arch>\efibind.h" for MSVC

simply edit the makefile's "VERSION" line to the new version, commit
that as its own commit, and do: "make test-archive". That'll make a
file in the current directory gnu-efi-$VERSION.tar.bz2 , with its top
level directory gnu-efi-$VERSION/ and the source tree under that.
Once you've tested that and you're sure it's what you want to release,
you do "make archive", which will tag a release in git and generate a
final tarball from it. You then push to the archive, being sure to
include the tag:
git push origin master:master --tags
And upload the archive wherever it's supposed to go.

Subject: [PATCH] Add support for 32-bit ARM
This adds support for 32-bit ARM using an approach similar to the one used for
64-bit ARM (AArch64), i.e., it does not rely on an objcopy that is aware of EFI
or PE/COFF, but lays out the entire PE/COFF header using the assembler.
In the 32-bit ARM case (which does not have a division instruction), some code
has been imported from the Linux kernel to perform the division operations in
software.

Subject: [PATCH 2/4] Add support for cross compilation
This changes the logic that defines ARCH (and HOSTARCH) to take CROSS_COMPILE
into account. Also, $prefix is not assigned, so that the default will be what
is on the path rather than hardcoded in /usr/bin.
This results in the build doing the right thing if CROSS_COMPILE is set in the
environment and no ARCH or prefix options are passed to make, aligning it with
most other CROSS_COMPILE compatible projects.

Subject: [PATCH] always observe EFIAPI calling convention when calling
STO.SetAttribute
We have to consider the following cases wrt. the PRINT_STATE.Output and
PRINT_STATE.SetAttr EFIAPI function pointers, especially when building for
x86_64 with gcc:
(1) The compiler is new enough, and EFIAPI actually ensures the Microsoft
calling convention. In this case everything happens to work fine even
if we forget uefi_call_wrapper(), because the wrapper would expand to
a normal C function call anyway.
(2) Otherwise (ie. gcc is old), EFIAPI expands to nothing, and we must
take into account the called function's origin:
(2a) If the callee that is declared EFIAPI is *defined* inside gnu-efi,
then EFIAPI means nothing for the callee too, so caller and callee
only understand each other if the caller intentionally omits
uefi_call_wrapper().
(2b) If the callee that is declared EFIAPI is defined by the platform
UEFI implementation, then the caller *must* use
uefi_call_wrapper().
The PRINT_STATE.Output EFIAPI function pointer is dereferenced correctly:
the PFLUSH() distinguishes cases (2a) from (2b) by using IsLocalPrint().
However use of the PRINT_STATE.SetAttr EFIAPI function pointer is not
always correct:
- The PSETATTR() helper function always relies on the wrapper (case (2b)).
This is correct, because PRINT_STATE.SetAttr always points to a
platform-provided function.
- The DbgPrint() function contains two incorrect calls: they mistakenly
assume case (2a) (or case (1)), even though the pointer always points to
a platform function, implying (2b). (The error is masked in case (1).)
Fix them.

Consequently, when your program calls DbgPrint() via the DEBUG() macro,
it fails to set up the stack correctly (it does not pass the arguments

However, va_start() inside DbgPrint() *assumes* that stack.
