56d881b917 Remove LDR_LOG2_PGSZ, ia64_pgtbl and ia64_pgtblsz. They are part of
a WIP and not used yet.

0463b4a2fb Major rework of the ia64 loaders. The two primary objectives are:
1. Make libefi portable by removing ia64 specific code and build
   it on i386 and amd64 by default to prevent regressions. These
   changes include fixes and improvements over previous code to
   establish or improve APIs where none existed or when the amount
   of kluging was unacceptably high.
2. Increase the amount of sharing between the efi and ski loaders
   to improve maintainability of the loaders and simplify making
   changes to the loader-kernel handshaking in the future.

The version of the efi and ski loaders are now both changed to 1.2
as user visible improvements and changes have been made.

932d8c46a2 Extend struct devdesc with a unit field, called d_unit. Promote the
device (kind) specific unit field to the common field. This change
allows a future version of libefi to work without requiring anything
more than what is defined in struct devdesc and as such makes it
possible to compile said version of libefi for different platforms
without requiring that those platforms have identical derivatives
of struct devdesc.

4750e08f7b Add loader(8) variables for RB_DFLTROOT, RB_MUTE, and RB_PAUSE:
"boot_dfltroot", "boot_mute", and "boot_pause" respectively.

05d0bf79ed Remove the last vestiges of the userconfig option. None of this actually
did anything, so this commit should be considered a NO-OP.

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.

bit-fields. Unify the PTE defines accordingly and update all
uses.

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.

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.

0761a64f29 o Fix a size calculation based on a 8KB page, while under EFI
pages are 4KB.
o  As a second order fix, don't assume we have enough space
   after the bootinfo block left in a page to hold the memory
   map.
o  A third order fix as that we removed the assumption that a
   bootinfo block fits in a single 8KB page.

92caa29d8e Add boot_serial and boot_multicons variables to set RB_SERIAL and
RB_MULTIPLE since this seems to be the easiest way to add these flags
for non-forth loaders etc.

23c12a63cf o Remove namespace pollution from param.h:
-  Don't include ia64_cpu.h and cpu.h
   -  Guard definitions by  _NO_NAMESPACE_POLLUTION
   -  Move definition of KERNBASE to vmparam.h

o  Move definitions of IA64_RR_{BASE|MASK} to vmparam.h
o  Move definitions of IA64_PHYS_TO_RR{6|7} to vmparam.h

o  While here, remove some left-over Alpha references.

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.

24ffe931b9 Lookup the EFI_FPSWA driver and pass the interface pointer through to the

in efifpswa.h from the Intel FPSWA manual (urk).

de76c8189e Remove bootinfo.bi_kernel. It isn't used by the kernel. struct bootinfo
should go away on ia64, we should be loader metadata based since that is
the only way we can boot (loader, skiload).

6544e18249 Tidy up a little - don't try to print anything or enable interrupts after

before we jump into the kernel.
