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.

593bbd2195 Revert the last change. Masking only 2 MSBs of the virtual address
to get the physical address doesn't work for all values of KVA_PAGES,
while masking 8 MSBs works for all values of KVA_PAGES that are
multiple of 4 for non-PAE and 8 for PAE.  (This leaves us limited
with 12MB for non-PAE kernels and 14MB for PAE kernels.)

To get things right, we'd need to subtract the KERNBASE from the
virtual address (but KERNBASE is not easy to figure out from here),
or have physical addresses set properly in the ELF headers.

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.

da6d4298b7 Because the BTX mini-kernel now uses flat memory mode and clients
are no longer limited to a virtual address space of 16 megabytes,
only mask high two bits of a virtual address.  This allows to load
larger kernels (up to 1 gigabyte).  Not masking addresses at all
was a bad idea on machines with less than >3G of memory -- kernels
are linked at 0xc0xxxxxx, and that would attempt to load a kernel
at above 3G.  By masking only two highest bits we stay within the
safe limits while still allowing to boot larger kernels.

(This is a safer reimplmentation of sys/boot/i386/boot2/boot.2.c
rev. 1.71.)

ce34bd6bca - Fix a couple of improper uses of leal in the previous space saving
commits.  For some reason I thought the scale factor was a shift count
  rather than the multiplicand (that is, I thought leal (%eax,%edx,4) was
  going to generate %eax + %edx << 4 rather than %eax + %edx * 4).  What
  I need is to multiply by 16 to convert a real-mode (seg, offset) tuple
  into a flat address.  However, the max multiplicand for scaled/index
  addressing on i386 is 8, so go back to using a shl and an add.
- Convert two more inter-register mov instructions where we don't need to
  preserve the source register to xchg instructions to keep our space
  savings.

d64e328e3c Tweak the code to handle intercepting BIOS calls to int 0x15 to shave
another 16 bytes off of BTX (and thus boot2):
- Compare against the value of %eax that is saved on the stack instead of
  loading it into %eax (which requires saving the current %eax on the
  stack).
- Use %ch to examine the keyboard flag state in the BIOS to see if
  Ctrl-Alt-Del is pressed instead of %al so we don't have to save %eax on
  the stack anymore.

4b9657e974 Optimize the int 15/87 handler for space to shave another 16 bytes off of
BTX (and thus boot2):
- Don't bother saving %eax, %ebx, or %ecx as it is not necessary.
- Use a more compact sequence to load the base value out of a GDT entry
  by loading the contiguous low 24 bits into the upper 24 bits of %eax,
  loading the high 8 bits into %al, and using a ror to rotate the bits
  (2 mov's and a ror) rather than loading the pieces in smaller chunks
  (3 mov's and a shl).
- Use movzwl + leal instead of movl + movw + shll + addl.
- Use 'xchgl %eax,%foo' rather than 'movl %eax,%foo' for cases where
  it's ok to trash %eax.  xchgl %eax, foo is a 1-byte opcode whereas the
  mov is a 2-byte opcode.
- Use movzwl rather than xorl + movw.

For 32-bit SDRAM systems, enable D16 to D31 in the PIO controller.

Shave 8 bytes from the object size by using AT91C_BASE_PIOA directly
and by not assigning PIO_BSR to 0 in the DBGU init.  That's a nop in
two ways (everything defaults to peripheral A, and writing 0 changes
nothing).

8015f1dbb8 Merge from p4:
Many places used #define FOO ((unsigned int) 0x23) where a simpler
#define FOO 0x23u would have sufficed.  This practice is overly
verbose and has the disadvantage that you can't say

	#if FOO == BAR
	#endif

because the extra "unsigned int" tokens choke cpp's little brain.
Migrate to the latter style to allow use in preprocessor statements.
The two are the same semantically anyway in a C context (at least for
the uses they are put to presently, C gurus can explain to me how they
differ).

e06ca69b2f Recovery boot loader for the AT91 family of processors. Download it
via xmodem to the DBGU port when the AT91 comes up in recovery mode.
The recovery loader will then load your program via xmodem into SDRAM
at 1MB which can do its things.  It needs to be tweaked to the
specific board one is using, but it fits in < 1kB (all of Atmel's ARM
products have at least 8kb of SRAM that I can tell, so this should
work for them all).

Parts of this code were provided by Kwikbyte with copyright
specifically disclaimed.  I heavily modified it to act as a recovery
loader (before it was a bootstrap loader) and to optimize for size
(before I started the size was closer to 8k).

Bootstrap loaders for SPI and IIC to follow.

cd86367a5a When enabling A20 put upper limit on amount of time we wait for the keyboard
controller to get ready (65K x ISA access time, visually around 1 second).
If we have wait more than that amount it's likely that the hardware is a
legacy-free one and simply doesn't have keyboard controller and doesn't
require enabling A20 at all.

This makes cdboot working for MacBook Pro with Boot Camp.

e4846391da In moduledir_readhints() cast the value returned by sizeof() to ssize_t
when checking whether it's greater than a struct stat st_size in order
to also catch the case when st_size is -1. Previously this check didn't
trigger on sparc64 when st_size is -1 (as it's the case for a file on
a bzipfs, TFTP server etc.), causing the content of the linker hints
file to be copied to memory referenced by a null-pointer.

e4f5866fd5 For the cases when loading bzip2-compressed kernels enabled use last
3MB of physical memory for heap instead of range between 1MB and 4MB.
This makes this feature working with PAE and amd64 kernels, which are
loaded at 2MB. Teach i386_copyin() to avoid using range allocated by
heap in such case, so that it won't trash heap in the low memory
conditions.

This should make loading bzip2-compressed kernels/modules/mfs images
generally useable, so that re@ team is welcome to evaluate merits
of using this feature in the installation CDs.

f668cd5df7 If LOADER_BZIP2_SUPPORT is defined allocate heap in the 1MB-4MB range to
provide enough room for decompression (up to 2.5MB is necessary). This
should be safe to do since we load i386 kernels after 8MB mark now, so
that 16MB is the minimum amount of RAM necessary to even boot FreeBSD.

This makes bzip2-support  practically useable.

915dad0e92 Long-long time ago, when the trees were large and memory expensive amount of
memory directly available to loader(8) and friends was limited to 640K on i386.
Those times have passed long time ago and now loader(8) can directly access
up to 4GB of RAM at least theoretically. At the same time, there are several
places where it's assumed that malloc() will only allocate memory within
first megabyte.

Remove that assumption by allocating appropriate bounce buffers for BIOS
calls on stack where necessary.

This allows using memory above first megabyte for heap if necessary.
