+- 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
