Move all command code into its own directory
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.
