[U-Boot-Users] Can ethernet be disabled?

[David Miles]

I'm porting u-boot to a custom PXA255 board.  At present there is no network 
interface so I'm only interested in loading data over a serial port.  Can I 
disable network support pre-compilation to cut down the size of u-boot?

ie. Is there an equivalent of 
" #define CONFIG_LCD              0 "
to disable network support.?  

So far builds fail unless I define at least one network controller.

Cheers

Could you please be more specific?

- which version of u-boot?
- in what way does your build fail?

I've just been through the process of porting u-boot to a freshly
developed PXA255-base board, and even though I didn't define any network
controller I did't experience any such weird dependency problem.

Perhaps what you're seeing is a side-effect of some configuration error?

It doesn't  work  this  way.  "#define  CONFIG_LCD  0"  is  extremely
misleading.  Don't  ever  do  this.  Either #define the option (which
enables it, no matter which value the variable has, if any at all, or
do NOT #define it.

Don't  #define  network  options  (including  the   network   related
commands, and no network support will be included.
