Hi Habeeb,

as you can see LM4F "BSP" is just a variant of LM3S69xx BSP nothing 
more. I guess it would be useless to rename in source tree (since how 
users will find it when looking for LM3S69 bsp then?), but IMHO it may 
be much better to fix wiki and provide BSP information there...

Anyway, even current LM4F120 BSP wiki contains following information in 
bold font:

NOTE: Please note that after the release of the LM4F Stellaris family, 
TI went ahead and rebranded whole Stellaris LM4F line to Tiva C Series 
or Tiva C TM4C family. See below for a link to table listing 
corresponding parts of LM4F and TM4C families

if you think the note is not enough, feel free to add/edit as you like.

Thanks,
Karel
