This is not correct. The ELDK does not do this. The  ELDK  is  not  a
Linux source tree.

Also, this setting is hardware dependent and differs  from  board  to
board.

Then   probably   other   changes   /   initializations   (port   pin
configurations) are needed as well.

This idepends on your hardware. Study the schematics.

Compare U-Boot code and other board definitions.

A secure program has to be robust: it  must  be  able  to  deal  with
conditions  that "can't happen", whether user input, program error or
library/etc. This is basic damage  control.  Buffer  overflow  errors
have nothing to do with security, but everything with stupidity.
