My guess is they just haven't bothered updating the bootloader code for
this part to define that
area as being RAM - considering they've not (AFAIK) even updated the code
to use the UART FDR, or
put an SPI flash loader in the 2470, useful bootloader features don't seem
to be a very high
priority at NXP....
