Normall the ROM base is 0XFFF00000 which give us  a 1MByte addressing range.
In the spec of the PPC8245 (MPC8245UM23.pdf) is stated that from 0XFF000000
giving 16MByte of addressing space.
The Boot vector of the MPC8245 can be choosen to be either at 0XFFF00100 of
at 0X00000100
How can I use a 4MByte FLASH with PPCBoot, knowing that I need to use the
whole 4MBytes of available space
