Re: [Ltib] EHCI HCD / Disappears sometimes... / Dependencies

[Stuart Hughes]

Hi Franz,

This is a kernel configuration question, not really a LTIB question. 
What happens when you build the kernel is that a seed kernel config (you 
can see this in ./ltib -m config (for example):

      kernel (Linux 2.6.15-ep93xx)  --->
(linux-2.6.x.config) kernel config

is input to the kernel configuration system (conf or mconf if 
interactive).  This will generate an updated xxxxxx.dev file (in this 
case linux-2.6.x.config.dev).  Options will dissapear depending on the 
kernel's constrains (if you turn off USB support, all options depending 
on this will dissapear).

You don't need to do a distclean to recover your configuration,  you can 
simply remove the updated kernel config that has been computed.  So
rm config/platform/_target_/*.dev and the re-run ./ltib

Regards, Stuart
