e4ec6fb518 Don't hardcode unit 0 for the current device if we're loaded from an
EFI file system. When booting from a CD and there's already an EFI
system partition on the disk, setting the current device to unit 0
will select the harddisk. This invariably breaks installing FreeBSD
when other operating systems have been installed before.

We obviously want to do the same when we're booting over the network.
Maybe later.

48a0b96a50 Enable the i386 loader to load and run an amd64 kernel. If this puts
things over floppy size limits, I can exclude it for release builds or
something like that.  Most of the changes are to get the load_elf.c file
into a seperate elf32_ or elf64_ namespace so that you can have two
ELF loaders present at once.  Note that for 64 bit kernels, it actually
starts up the kernel already in 64 bit mode with paging enabled.  This
is really easy because we have a known minimum feature set.

Of note is that for amd64, we have to pass in the bios int 15 0xe821
memory map because once in long mode, you absolutely cannot make VM86
calls.  amd64 does not use 'struct bootinfo' at all.  It is a pure loader
metadata startup, just like sparc64 and powerpc.  Much of the
infrastructure to support this was adapted from sparc64.

6257165c74 Pass the HCDP table address to the kernel. If no such table exists,
NULL is passed. The address of the HCDP table can be found by
iterating over the configuration tables in the EFI system table.
To avoid more duplication, a function can be called with the GUID
of interest. The function will do the scanning. Use the function
in all places where we iterate over the configuration tables in
an attempt to find a specific one.

Bump the loader version number as the result of this.

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.

ea16741fc0 The boot manager sets the watchdog timer to 5 minutes before invoking
a boot option. When the timer expires the machine is rebooted.
Disable the watchdog timer for 2 reasons:
o  We're an interactive program. We cannot guarantee that we've
   booted the kernel in the time available to us. There have been
   situations where netbooting the right kernel took 2 tries and
   more time than given. Not to speak of the normal behaviour to
   have the loader sitting at the prompt while the user is off
   doing other things (such as figuring out what to type next ;-)
o  We may not boot a kernel at all. We may exit as the result of
   the user typing quit (assuming it took less than 5 minutes to
   type it :-). It is documented that loaders should have disabled
   the watchdog timer if they return to the boot manager. Not doing
   so would cause a reboot while in the boot manager. This appears
   to be harmless, besides of course the actual reboot.

487d404b1b In efi_cons_poll we check if a key is present (pending) by checking
the signaled state of the apropriate event. As a side-effect of
checking the event, it's signaled state is cleared if it was set.
In efi_cons_getchar we used to wait for the apropriate event to be
signaled before reading a character. This however does not work if
we poll before reading the characteri, such as during autoboot. On
a more compliant EFI implementation this resulted in the behaviour
that hitting a key during autoboot would stop the countdown, but
would then wait for a new character to arrive instead of reading
the already pending key that stopped the countdown.

The correct behaviour for efi_cons_getchar is to try to read a key
and if none is pending, to wait for the apropriate event to signal
the arrival of a new key.

Note that with the previous behaviour, the second key would determine
how the autoboot was interrupted. This would indicate that the first
key got lost. This indicates that EFI does not necessarily maintain
a queue of pending keys. FWIW...

aef78848af Remove a left-over virtual mapping of uncached I/O port space.
Previous kernels unwantingly depended on this mapping, but as
of version 1.123 of src/sys/ia64/ia64/machdep.c this dependency
has been removed. Consequently, one has to update the kernel
before updating the loader. The documented/recommended upgrade
will suffice in this case.

Due to a visible (from the kernels point of view) change in
behaviour, bump the loader version number from 0.3 to 1.0.

914ecdc8ea Work around some nasty bugs on the [beta] Itanium2's E1000 UNDI driver.
Bug#1: The GetStatus() function returns radically different pointers that
do not match any packets we transmitted.  I think it might be pointing to
a copy of the packet or something.  Since we do not transmit more than
one packet at a time, just wait for "anything".

Bug#2: The Receive() function takes a pointer and a length.  However, it
either ignores the length or otherwise does bad things and writes outside
of ptr[0] through ptr[len-1].  This is bad and causes massive stack
corruption for us since we are receiving packets into small buffers on
the stack.  Instead, Receive() into a large enough buffer and bcopy the
data to the requested area.

77de753f65 Improve self-relocation:
o  We don't expect the PLT relocations to follow the .rela section
   anymore. We still assume that PLT relocations are long formed,
o  Document register usage,
o  Improve ILP,
o  Fix the FPTR relocation by creating unique OPDs per function.
   Comparing functions is valid now,
o  The IPLT relocation naturally handles the addend. Deal with it.
   We ignore the addend for FPTR relocations for now. It's not at
   all clear what it means anyway.

Fix ABI misinterpretation:
o  For Elf_Rela relocations, the addend is explicit and should not
   be loaded from the memory address we're relocating. Only do that
   for Elf_Rel relocations (ie the short form).
o  DIR64LSB is not the same as REL64LSB. DIR64LSB applies to a
   symbol (S+A), whereas REL64LSB applies to the base address (BD+A),
