in sys/boot/i386/libi386/biosdisk.c. Otherwise, when DISK_DEBUG is
enabled, the DEBUG() macros will clobber those fields, and cause the
probing to always fail mysteriously when debugging is enabled.
When we open the disk, check the type of partition table, that has
been detected. If this is BSD label, then we assume this is DD mode.

It uses new API from the part.c to work with partition tables.
Update userboot's disk driver to use new API. Note that struct
loader_callbacks_v1 has changed.
all diskN aliases for providers (which more or less corresponds to how the
x86 version behaves) but instead probe only those listed in the boot-device
OFW environment variable. This has the following advantages:
- avoids otherwise unavoidable OFW warnings about failures to open disks
for which aliases exist but no actual hardware is connected
- avoids issues due to different diskN naming schemes
- aligns us with Solaris

often modified directory created symbolic links points to - it cause
unnecessary full rebuilds each time make runs when directory is changed.
So do it only if symbolic link does not exists, which usually means that
objdir is clean anyway.

100 bytes from the binary with silly tricks. Hope to get this small
enough to run on the models that have 4k SRAM. We are close compiled
for the at91rm9200, but still need to trim for the target.
(x86 assembler optimization disabled for now because it
requires the new .cfi_* directives that is not supported
by base system binutils).

update for ZFS. It seems that this does not really affect anything except
the help command. Nevertheless, rearrange things so loaddev is set only
once in all cases in order to get it right.

a single device to be opened multiple times concurrently unfortunately
isn't sufficient with ZFS. This is due to the fact, that ZFS may open
different partitions of a single device simultaneously. So the best we
can do in this case is to cache the lastly used device path and close
and open devices in ofwd_strategy() as needed.

Partitions are created based on data in dts file which are

The generic ELF loading code maps the kernel into low memory
by subtracting KERN_BASE. So the copyin/copyout/readin functions
are always called with low addresses. This code finds the largest
DRAM block from the U-Boot memory map and adds that base to
the addresses.
In particular, this fixes ubldr on AM3358, which has DRAM
mapped to 0x80000000 at power-on.
