There are a lot of unrelated files in common, including all of the commands.
Moving them into their own directory makes them easier to find and is more
logical.

Some commands include non-command code, such as cmd_scsi.c. This should be
sorted out at some point so that the function can be enabled with or without
the associated command.

Unfortunately, with m68k I get this error:

m68k:  +   M5329AFEE
+arch/m68k/cpu/mcf532x/start.o: In function `_start':
+arch/m68k/cpu/mcf532x/start.S:159:(.text+0x452): relocation truncated to fit: R_68K_PC16 against symbol `board_init_f' defined in .text.board_init_f section in common/built-in.o

I hope someone can shed some light on what this means. I hope it isn't
depending on the position of code in the image.

make the use of legacy image format configurable through
the config define CONFIG_IMAGE_FORMAT_LEGACY.

When relying on signed FIT images with required signature check
the legacy image format should be disabled. Therefore introduce
this new define and enable legacy image format if CONFIG_FIT_SIGNATURE
is not set. If CONFIG_FIT_SIGNATURE is set disable per default
the legacy image format.

Added support to load a bitstream image in chunks by reading it in
chunks from SD/MMC.
Command format:
loadfs [dev] [address] [image size] [blocksize] <interface>
       [<dev[:part]>] <filename>
Example: fpga loadfs 0 1000000 3dbafc 4000 mmc 0 fpga.bin

Added support to load partial bitstreams.
The partial bitstreams can be loaded using the below commands
Commands:
fpga loadp <dev> <addr> <size>
fpga loadbp <dev> <addr> <size>
The full bit streams can be loaded using the
old commands(fpga load and fpga loadb).

Clean up partial, full and compressed bitstream handling.
U-Boot supports full bitstream loading and partial
based on detection which is not 100% correct.
Extending fpga_load/fpga_loadbitstream() with one more
argument which stores bitstream type.

Here is the set of command which has been performed
to proof this feature.

gzip < fpga.bin > fpga.bin.gz
mkimage -A arm -O u-boot -T firmware -C gzip \
-a 20000000 -n "zc702_fpga_bin" -d fpga.bin.gz fpga.bin.gz.ub

tftp 100000 fpga.bin.gz.ub
fpga loadmk 0 100000

This flow should speedup loading bitstream data
from external memory and save image footprint in non volatile
memory.
