The device appears repeatedly in multiples of its port-size (in bytes) X depth. That is, 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
map.
An 8 Kbyte device is used (16 Kbyte and 32 Kbyte devices can also be used) so it appears repeatedly in 8Kbyte
multiples starting from C2000000.
Set by hard-reset configuration.
