Patches for next merge window

[Sascha Hauer]

Hi all,

Here are some patches I created to boot my systems faster. With these
I managed to bring a phyCORE-i.MX35 to the shell in ~0.4s using a kernel with
integrated ramfs which only contains a busybox. Here is a bootlog:

Also in this series are some patches for the fun of it: They add a -e
option to echo and allow for fancy shell prompts. Try
PS1="\e[1;32mbarebox@\e[1;31m\h\e[0m:\w " to get a coloured shell prompt.
As these features add size to the binary image without any real value they
are disabled by default.
