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.
2
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.
3
Initially at h0F000000 - h0F00FFFF, set by hard reset configuration.
4
Refer to the MPC8272 PowerQUICC II
map.
5
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.
6
Set by hard-reset configuration.
