9add094157 Add the flags parameter to the disk_open() function and DISK_F_NOCACHE
flag, that disables the caching of partition tables metadata.
Use this flag for floppies in the libi386/biosdisk driver.

f9cd8b07a4 Almost each time when loader opens a file, this leads to calling
disk_open(). Very often this is called several times for one file.
This leads to reading partition table metadata for each call. To
reduce the number of disk I/O we have a simple block cache, but it
is very dumb and more than half of I/O operations related to reading
metadata, misses this cache.

Introduce new cache layer to resolve this problem. It is independent
and doesn't need initialization like bcache, and will work by default
for all loaders which use the new DISK API. A successful disk_open()
call to each new disk or partition produces new entry in the cache.
Even more, when disk was already open, now opening of any nested
partitions does not require reading top level partition table.
So, if without this cache, partition table metadata was read around
20-50 times during boot, now it reads only once. This affects the booting
from GPT and MBR from the UFS.

5f5ec09bfb Determine kernel load address dynamically from u-boot memory map.
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.

0ed948780c Initial support of loader(8) for ARM machines running U-Boot.
This uses the common U-Boot support lib (sys/boot/uboot, already used on
FreeBSD/powerpc), and assumes the underlying firmware has the modern API for
stand-alone apps enabled in the config (CONFIG_API).

Only netbooting is supported at the moment.

7572ed5a08 Eliminate artificial increasing of 'netdev_opens' counter in loader's net_open().
This was introduced as a workaround long time ago for some Alpha firmware
(which is now gone), and actually prevented net_close() to ever be
called.

Certain firmwares (U-Boot) need local shutdown operations to be performed on a
network controller upon transaction end: such platform-specific hooks are
supposed to be called via netif_close() (from within net_close()).

This change effectively reverts the following CVS commit:

    sys/boot/common/dev_net.c

    revision 1.7
    date: 2000/05/13 15:40:46;  author: dfr;  state: Exp;  lines: +2 -1
    Only probe network settings on the first open of the network device.
    The alpha firmware takes a seriously long time to open the network device
    the first time.

Also suppress excessive output while netbooting via loader, unless debugging.

While there, make sys/boot/uboot more style(9) compliant.
