- Every driver should have a remove function
- Mount without options should show mounted filesystems
- Add/fix help texts for commands
- mm is broken. Add common option parsing for mm/md
- Clean up make system. Currently I think there are many things from the linux make
  system which are not needed for U-Boot.
- Rename vmlinux -> u-boot
- get/set for nonextisting parameters crashes
- There is a xmalloc function which panics when out of memory. Use this function
  where we don't want to check for oom. Same applies to strdup/xstrdup.
- Implement current work directory
- cleanup common.h. There are far too many things in it where we better have a seperate
  header file.
- Rewrite network stack. The one-loop-for-all-protocols stack is just too ugly and
  big and uses thousands of global variables. Identify common functions and make
  a loop per network protocol
- Cleanup cpu/*. Many functions there are not cpu specific. For example the cache
  functions for arm are common for most arm processors.
- Implement a info command for malloced space. Use it to find memory holes.
- U-Boot used to have support for different consoles. The old code was huge and
  ineffective, so I removed it. Reimplement it using the driver model.
- Board support should go to arch/*/boards/*
- Move SoC specific header files from include/ to include/asm/arch/
- The header files in include/asm-linux/ are i386 specific. Make it work on your
  i-Book (bigendian...)
- Globbing support? Might be too expensive, but on the other hand, if you have the
  space, why not?
- FS support is not optional eventhough the Kconfig system claims it.
- Implement protect/unprotect support for cfi devices.
- patch hush.c so that you can get/set device parameters with dev.param= and remove
  get/set applets
- Implement a command 'countdown' or similar. It should delay the boot process and
  interrupt it if a certain string is received. The string could be any key, ctrl-c
  or a certain string. Maybe like this:
  countdown -m msg -t timeout -x [ctrl-c|anykey|string]
  If done, remove the corresponding stuff from common/main.c
- Implement 'rm'
- ARCH=linux should catch ctrl-c
- Several .c/.h files do not have GNU/copyright headers.
- the mount command currently does not accept a full path (i.e. /dev/nor0) but
  only a device id string (nor0). This sucks.
- The cramfs driver currently uses direct memory accesses instead of read(). This disqualifies it
  for real block devices.
- Add documentation for:
  - driver model
  - device parameter
  - big picture
