[LinuxBIOS] x86 cache-as-ram has broken ppc

[Greg Watson]

Hi,

Someone (YhLu I think) has added x86 specific commands to config/ 
Config.lb using the CONFIG_USE_INIT option. This option is used by  
the PPC port, which is now broken because of these changes. Also, lib/ 
Config.lb was changed to comment out some initobject lines that were  
also used by PPC.

As a rule, I don't believe there should be any architecture specifics  
in config/Config.lb. These really belong in the arch tree somewhere.
