Address
The device appears repeatedly in multiples of its port-size (in bytes) X depth. E.g., BCSR0 appears at memory
locations 4700000, 4700020, 4700040..., while BCSR1 appears at 4700004, 4700024, 4700044... and so on.
The internal space of the ATM UNI control port is 256 bytes, however, the minimal block size that may be controlled
by the GPCM is 32 KBytes.
Initially at h0F000000 - h0F00FFFF, set by hard reset configuration.
Refer to the MPC8272 PowerQUICC II
internal memory map.
An 8-Kbyte device is used (16- and 32-Kbyte devices can also be used) so it appears repeatedly in 8 Kbyte multiples
starting from FFF00000.
