[Ltib] Support for LPC3152 on LTIB.

[hugo Alexandre]

 Hello,

I'm trying to create Linux 
files (uBoot, uImage, rootfs...) for LPC3152. I've read that LTIB 
supports LPC3152, but I couldn't find this option on LTIB initial 
configurations (the menu that appears first time you run ./ltib ). I 
just found the option for LPC3131 in this menu.
I would like to know in which menu could I find this option. Moreover, should I need to change any files to do that?

Thanks,

Hugo
