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.

7608f7cb80 Fix the initialization of the protocol:
o  Query the state field of the protocol mode to determine whether
   we need to start and/or initialize the protocol. When we're
   loaded across the network, the protocol has already been started
   and is already initialized. When no networking has happened yet,
   we have to start and initialize the protocol ourselves.
o  After initialization, we have to set the receive filters. Not
   doing this results in a deaf interface. We set the unicast and
   broadcast filters. Multicast may not be supported. This specific
   change fixes the problem we had that we could not netboot if
   the loader was started from the EFI shell.
o  To help future debugging, add a function that dumps the current
   mode of the interface. It's conditional on EFINET_DEBUG.
o  To help in runtime problems, emit a diagnostic message when we
   could not initialize the protocol properly.

c61a2c84f0 Don't blindly dereference f->f_devdata as if it's always a pointer to
an efi_devdesc structure. When we're netbooting, f->f_devdata holds
the address of the network socket variable. Dereferencing this caused
some very unpredictable behaviour, including proper functioning.
So, as a sanity check, we first make sure f->f_dev points to our
own devsw. If not, the open will fail before we use f->f_devdata.

This solves the netboot hangs I invariably got whenever I used the
latest toolchain to compile the EFI loader.

9423456018 o Make efinet_put a blocking call by waiting for the protocol
layer to signal transmission of the packet. This resolves the
   problem I'm seeing that an immediate call to net->Receive
   after calling net->Transmit returns EFI_DEVICE_ERROR. This
   condition seems to be sufficiently persistent that BOOTP and
   RARP fail.
o  While here, unify all functions to have 'nif' defined. Some
   have it as arguments. The others now have them as locals. We
   now always get the protocol interface by using the 'nif' var.

The current status of netbooting is that even though we now reliably
have BOOTP working (again), opening a file (ie loading a kernel)
across the network causes the loader to hang. I'm working on that now.

ede9f03a1a Fix the beforeinstall target. We install ${PROG}.help if loader.help
exists, otherwise we install it anyway. I interpret this as a very
high desire to install ${PROG}.help. Alas, ${PROG}.help doesn't exist
at the moment and neither does loader.help, so in practice this just
doesn't work, no matter how you interpret it. The compromise is to
install ${PROG}.help IFF it exists. I realize we lost creativity with
this commit, but style should have been preserved, AFAICT :-)

fb74e5f595 Add splitfs vfs layer into libstand, which allows loading big kernels and
modules split across several physical medias. Following is how it works:

The splitfs code, when asked to open "foo" looks for a file "foo.split"
which is a text file containing a list of filenames and media names, e.g.

	foo.aa "Kernel floppy 1"
	foo.ab "Kernel floppy 2"
	foo.ac "Kernel and modules floppy"

For each file segment, the process is:

- try to open the file
- prompt "Insert the disk labelled <whatever> and press any key..."
- try to open the file
- return error if file could not be located

RE team is free to use this feature in the upcoming 5.0-DP1.

0c6ec4aca0 Declare time(not3) instead of depending on namespace pollution 3 layers
deep in <stand.h> to eventually include <time.h> to declare the user
version.

This is not quite the right place to declare it, but <stand.h> would
be worse because time() is very MD so it isn't in libstand.

Many places in the boot sources still get the user version using only
1 layer of pollution (#include <sys/time.h>.  Some pollute themselves
directly (#include <time.h>).  But the boot Makefiles are too broken
to enable warnings for redeclarations.

870fb18bc1 Oops, the previous revision (1.35) broke booting from floppies
because the buffers we use could end up spanning a 64k boundary.
Unfortunately it causes too much bloat (228 -> 72 bytes free) to
just reinstate the old malloc() function.

Instead, define a structure that contains all 4 buffers which must
not cross 64k boundaries. We allocate a 64k-aligned instance in
main() using the magic that was in the old boot2 malloc() function.
This brings the free space down to 168 bytes, but that is still
better than it was before revision 1.35 (136 bytes).

52e85481fd Make the alpha boot1 work on filesystems that have a block size

block size, so there is no longer a static limit.

Simply increasing the buffer size from 8k to 16k as done on the

to overshoot boot1's 48k runtime memory limit.

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).

8e92224a8a This is used in C, not C++. functions with no args have func(void) in our
kernel.

ce20386909 Initialize first to -1; this will create a (nearly) empty file on failure,
instead of looping until the disk is full.  This kind of failure can
especially happen when a version of awk that doesn't support POSIX
character classes is used.

6a50ba658c Remove a few more debugging bits and turn on twiddle output while reading
from the CD.  This turns off the dual console output to COM1.

1611ea8727 Add S4BIOS sleep (BIOS hibernation) and DSDT overriding support.
- Add S4BIOS sleep implementation.  This will works well if MIB
   hw.acpi.s4bios is set (and of course BIOS supports it and hibernation
   is enabled correctly).
 - Add DSDT overriding support which is submitted by takawata originally.
   If loader tunable acpi_dsdt_load="YES" and DSDT file is set to
   acpi_dsdt_name (default DSDT file name is /boot/acpi_dsdt.aml),
   ACPI CA core loads DSDT from given file rather than BIOS memory block.
   DSDT file can be generated by iasl in ports/devel/acpicatools/.
 - Add new files so that we can add our proposed additional code to Intel
   ACPI CA into these files temporary.  They will be removed when
   similar code is added into ACPI CA officially.

4c3bb58384 - If we are booted via cdboot, use bc_add() to instantiate the cd0 device
from the loader.
- Cleanup extract_currdev() some and add support for setting the currdev
  to cd0 when booted via cdboot.

0322b80600 Add a device driver for the BIOS device for CD-ROM's booted via El Torito
no emulation mode.  Unlike other BIOS devices, this device uses 2048 byte
sectors.  Also, the bioscd driver does not have to worry about slices
or partitions.
