As far as I know, all QED processors have the "wait" instruction.
All the 0x2??? processor ID values are QED processors. Here are the current
values:
#define C0_IMP_NEVADA 0x28
#define C0_IMP_RM7000 0x27
#define C0_IMP_MAGIC 0x25
#define C0_IMP_SONIC 0x24
#define C0_IMP_R5000 0x23
#define C0_IMP_R4650 0x22
#define C0_IMP_R4700 0x21
#define C0_IMP_R4600 0x20
I don't know which processors are SONIC, MAGIC, or NEVADA, but I think NEVADA
is the new RM5260 (a low-cost R5000).
