i got a board build around samsung's S3C2410 ( might be 2410a, i am not
pretty sure ) which in turn build on ARM920T core.

Both in ARM920T's specification and S3C210's specification, i get know
the processor core has seperated 16k 64-way set-association data cache
and instruction cache.  but, in the /proc/cpuinfo, i see,

Processor       : ARM/CIRRUS Arm920Tsid(wb) rev 0 (v4l)
BogoMIPS        : 99.94
Features        : swp half thumb
CPU implementor : 0x41
CPU architecture: 4T
CPU variant     : 0x1
CPU part        : 0x920
CPU revision    : 0
Cache type      : write-back
Cache clean     : cp15 c7 ops
Cache lockdown  : format A
Cache unified   : harvard
I size          : 8192
I assoc         : 32
I line length   : 32
I sets          : 8
D size          : 8192
D assoc         : 32
D line length   : 32
D sets          : 8

the info above indicates that the instruction cache and data cache is
8k 32-way set-association.  i am wondering which information is right?
and, how the linux generated the cpuinfo file?

The ARM920T's specification and S3C210's specification are right.

Use the source, Luke. Nobody here knows what kernel you're running or
what modifications have been made to the source, except you.
