f3beed66fa o Introduce efimd_va2pa() to translate addresses in efi_copy{in|out}()
and efi_readin(). This removes MD code from copy.c.
o  Don't unconditionally add pal.S to SRCS. It's specific to ia64.

any fake value.

a02efe9a7c o Don't build with -fpic. It's not needed and inconsistent with how
other constributions are compiled.
o  Remove powerpc specific additions to CFLAGS.

155dbcacfb Change the startup code to fix a memory leak and to allow us to
accept load options (=command line options).

The call graph changes from *entry*->efi_main->efi_init, where
efi_main is the EFI equivalent of main to *entry*->efi_main->main,
where main is what you'd expect. efi_main now is what efi_init was.
The prototype of main follows that of C. The first argument is argc
and the second is argv. There is no third argument.
Allocation of heap pages is now handled by the EFI library and it
now deallocates the pages when main() returns or when exit() is
called. This allows us to safely return to the boot manager (or
EFI shell) without leaks. EFI applications are responsible to free
all memory themselves.

Handling of the load options is a bit tricky. There are either no
load options, load options in ASCII or load options in Unicode.
The EFI library will translate the ASCII options to Unicode options
as to simplify user code. Since the load options are passed as a
single string (if present) and main() accepts argc and argv, the
startup code also has to split the string into words and build the
argv vector. Here the trickiness starts. When the loader is started
from the EFI shell, argv[0] will automaticly load the program name.
In all other cases (ie through the boot manager), this is not the
case. Unfortunately, there's no trivial way to check. Hence, a
set of conditions is checked to determine if we need to fill in
argv[0] ourselves or not. This checking is not perfect. There are
known cases where it fails to do the right thing. The logic works
for most expected cases, though. This includes the case where no
options are given.

46f8fdc34e Removed now unused INTERNALSTATICLIB.
INTERNALLIB now implies NOPIC and NOPROFILE.
Removed gratuitous NOMAN.

95cfc25d0d Back out last commit. I expect our bsd.*.mk gods to remove the need for
defining so many extra things in addition to INTERNALLIB.  We don't like
repetitive C code and we shouldn't for make code either.

3bf8b9cee3 NOPIC, NOPROFILE, NOMAN, and INTERNALSTATICLIB are redundant when using
INTERNALLIB now.

d1bdfb40fd -ffreestanding is the word.
(also resort some CFLAGS such that the more "important" value are first so
they are easier to see)

24ffe931b9 Lookup the EFI_FPSWA driver and pass the interface pointer through to the
kernel before we call ExitBootServices().  I've typed the definitions
in efifpswa.h from the Intel FPSWA manual (urk).
