Please note that the development of PPCBoot  has  been  discontinued.
The  code  is  frozen,  and  we don;t intend to add any new stuff any
more.  Development  continues  under  the  new  project  name  U-Boot
(Universal Boot Loader)>

But except for the name everything is more or less the same.

You should not try to add this function as is to U-Boot. Instead, add
the incomation contained in  it  (like  initial  values  for  special
registers, UPM tables and RAM init sequence) to your new board config
file  (include/configs/viper.h) resp. your new board dependend C code
(board/viper/viper.c).

Best regards,
