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.
