NOP instructions. This is needed to flush the instruction pipeline in the ARM920T core.
Writes to these locations have no effect.

Standby - 0x8093_000C - Read Only
Halt - 0x8093_0008 - Read Only
The Standby and Halt registers allow entry into the power saving modes. A
read to the Halt location will initiate a request for the system to enter Halt
mode, if the SHena bit is set in the DeviceCfg register in Syscon. Likewise a
read to Standby will request entry into Standby only when the SHena bit is set.
RSVD:
0x8093_0018 - Write
Writing to the TEOI location will clear the periodic Watchdog expired interrupt
(WEINT) and the 64 Hz TICK interrupt (TINT). Any data written to the register
triggers the clearing.
