The nios-32 arch is obsolete and broken. So it is removed.

Booting a "Multi-File Image" including a linux kernel, ramdisk and
fdt, generated with
mkimage -A ppc \
-O linux \
-T multi \
-C gzip \
-a 00000000 \
-e 00000000 \
-n "kernel-2.6+initrd+dtb" \
-d "vmlinux.bin.gz:ramdisk_image.gz:board.dtb" \
multi.bin
actually fails, because ramdisk start and end addresses
didn;t get initialized. This patch fixes this issue.
Tested on the KUP4K board.

If you really want to slim down U-Boot and you would rather use a higher
compression scheme (like LZMA), it'd be nice to disable gzip/zlib since
these code bases take up a significant amount of space.

Current code uses the second argument to bootm for standalone images to
override the load address specified in the image instead of passing all
parameters as is to the application. This behaviour is not documented
and not in line with how the go command works for standalone applications,
so we simply drop it.

In case we boot an image marked as 'standalone' and 'linux', the current
code erroneously tried to load a ramdisk.

There are a bunch of features in U-Boot that we want to enable by default,
and it's best if we centralize them in one place rather than updating all
the board files out there.

Prototype for gunzip/zunzip was only in lib_generic/gunzip.c and thus
repeated in every file using it. This patch moves the prototypes to
common.h and removes all prototypes distributed anywhere else.

Add lzop decompression support to the existing lzo bitstream handling
(think gzip versus zlib), and support it for uImage decompression if
CONFIG_LZO is enabled.
Lzop doesn't compress as good as gzip (~10% worse), but decompression
is very fast (~0.7s faster here on a slow ppc). The lzop decompression
code is based on Albin Tonnerre's recent ARM Linux lzo support patch.

Add #ifdefs where necessary to not perform relocation fixups. This
allows boards/architectures which support relocation to trim a decent
chunk of code.
Note that this patch doesn't add #ifdefs to architecture-specific code
which does not support relocation.

Added a arch_preboot_os() function that cpu specific code can implement to
allow for various modifications to the state of the machine right before

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.
Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.
This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt
dtt - Read temperature from Digital Thermometer and Thermostat
Usage:
dtt

Some systems have zlib.h installed in /usr/include/. This isn't the
desired file for u-boot code - we want the one in include/zlib.h.

Although load address and image start address are same address,
bootm command always does memmove.
That is unnecessary memmove and can be taken few milliseconds
(about 500 msec to 1000 msec).
If skip this memmove, we can reduce the boot time.

U-Boot's gunzip() function does not handle the return code
of zlib's inflate() function correctly. gunzip() is implemented
to uncompress all input data in one run. So the correct return
code for the good case is Z_STREAM_END. In case of insufficient
output buffer memory inflate returns Z_OK. For gunzip() this
is an error.
It also makes sense to me to call inflateEnd() also in case
of an error.

Add the ability to break the steps of the bootm command into several
subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go.
This allows us to do things like manipulate device trees before
they are passed to a booting kernel or setup memory for a secondary
core in multicore situations.
Not all OS types support all subcommands (currently only start, loados,
ramdisk, fdt, and go are supported).

Each architecture has different ways of determine what regions of memory
might not be valid to get overwritten when we boot. This provides a
hook to allow them to reserve any regions they care about. Currently
only ppc, m68k and sparc need/use this.

There is no need for each OS specific function to call do_reset() we
can just do it once in bootm. This means its feasible on an error for
the OS boot function to return.
Also, remove passing in cmd_tbl_t as its not needed by the OS boot
functions. flag isn't currently used but might be in the future so
we left it alone.

Created a bootm_start() that handles the parsing and detection of all
the images that will be used by the bootm command (OS, ramdisk, fdt).
As part of this we now tract all the relevant image offsets in the
bootm_headers_t struct. This will allow us to have all the needed
state for future sub-commands and lets us reduce a bit of arch
specific code on SPARC.
Created a bootm_load_os() that deals with decompression and loading
the OS image.
