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.

Based on a patch (from memory) from: arun

59c9bb54ee Speed up debugging in the context of unexpected traps by printing
the address of the image base of the loader. Given cr.iip, we can
use the symbol table to figure out what function caused the trap.

414c998fba Add command `hcdp'. This command dumps the DIG64 HCDP table if one
exists.

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.

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.

problem).

a6d81d83a2 Fix self hosted loader building. When you use a self configured gcc, it
detects and uses the gas section merge support.  As a result, a whole bunch
of new sections arrive, including .rodata.str1.8, which was not included
in our custom ldscript.ia64.  The result was a loader binary that EFI
rejected.

While here, collect the loader shell commands linker set and include it
in the data area rather than having its own section.

/boot/loader.efi was the last holdout for having a 100% self built ia64
system.

c459265de7 Pass the physical address of the bootinfo block to the kernel in
register r8. We continue to write the bootinfo block at the same
hardwired address, because the kernel still expects it there.
It is expected that future kernels use register r8 to get to the
bootinfo block and don't depend on the hardwired address anymore.

Bump the loader version once again due to the interface change.

a918e110c4 Add a quick and dirty way to determine where we're loaded from. We
only care if it's network or not at this time. If we're loaded from
the network, we set currdev (=loaddev) so that the kernel is loaded
from the network as well. In all other cases we initialize to disk.
This makes netbooting more convenient and can easily be enhanced to
do more elaborate checking.

4e357dbc58 The EFI loader has been improved a lot since it was first added.
Most significantly (from an interfacing point of view) is the
support for the FPSWA pointer passing. Even though that was added
4 months ago, it's probably not a bad idea to bump the version
number to reflect this.
