starting address for flash is 0xff00 0000 where there is a hardware reset
word .  even when i type in "go 0xffc00100", it still jumps to the part in
the flash where the embedded planetcore bootloader is stored (0xfff00100).
so, i decided to delete the hardware reset word... and now BDI cant even
connect to the target, as i get this output:

*** TARGET: resetting target failed
# PPC: unexpected response from target
- TARGET: target will be restarted in 10 sec
- TARGET: processing user reset request
- BDI asserts HRESET
- Reset JTAG controller passed
- Bypass check: 0x55 => 0xAA
- Bypass check: 0x55 => 0xAA
- JTAG exists check passed
- Target PVR is 0x00810101
- COP status is 0x05
- Check running state failed
- TARGET: Target PVR is 0x00810101
*** TARGET: resetting target failed
# PPC: unexpected response from target
- TARGET: target will be restarted in 10 sec

and it goes on and on... having some major regrets about deleting that
hardware reset word...  now i cant even connect to the embedded board.
