this is from head-armv.S:

  mrc     p15, 0, r9, c0, c0                      @ get Processor ID
@
@ Read processor ID register (CP#15, CR0).
@ NOTE: ARM2 & ARM250 cause an undefined instruction exception...
@ Values are:
@               XX01XXXX = ARMv4 architecture (StrongARM)
@               XX00XXXX = ARMv3 architecture
@               4156061X = ARM 610
@               4156030X = ARM 3
@               4156025X = ARM 250
@               4156020X = ARM 2
@

Couple of questions:
- What are the X 's  stand for in the above ?
- What about ARM 7 TDMI ?
AFAIK it implements architecture  4T
Is it handled in some other file ? If so, which one ?

TIA
Andy
