You should make sure that your ppcboot is linked to another address (not
the 0xfff00000), where your new ppcboot is located(whether in RAM or FLASH).
Change TEXT_BASE in your board directory to what you want. Be sure your
CFG_MONITOR_BASE is set to TEXT_BASE or hard coded to the same address.

No!!! Contact your HW engineer to help you to reprogram the HRCW.
Or if you are luck, and if your board had a switch to control /RSTCONF, you
can let 8260 use the default setting, and use the BDI program the HRCW.

Good luck!
