cmd line hist etc

[<sch...@t-...>]

Hi all,
well, ok then. From your comments I assume that I'll have to put this code
under a #ifdef and make it a compile-time option.

Please do understand my arguments, tough:
- blob is a bootloader, yes. Most of the time only loads the kernel in a
specified (quick) way, nothing else.

- when one gets a defective board from a customer, blob _could_ be used
as a diagnosis tool as well. I do not want to have first a special blob version
flashed, because then i'd have to change the system in order to check it. I
want to test the board as it is, right then when i get it. I could even
instruct a technican via phone, specially useful when the board is somewhere in
brazil and a machine does not work because of your board not running (which ist
exactly what will happen, think of murphy's law).

- a command line history is rather handy if you have to issue
several commands in a row and misspelled one

- that's why i keep adding test/diagnosis commands, because i _know_ i will need
exactly these commands later for customer support, because i need them _now_ to
get our new board running.

Does this sound reasonable, or am i completly wrong?
