There are no "config" files, nor is this process easily configured.
It is handled by the platform initialization code and is normally
just "hard wired" for the platform in question.

These values are set in "hal/arm/edb7xxx/current/hal_platform_setup.h",
but they are only set at boot time (by RedBoot).  If you need to set
them up specially, I'd suggest that you add the code to do this in the
platform initialization code, found in "hal/arm/edb7xxx/current/edb7xxx_misc.c"
