Hello,
Is it available any function which can be used in application (user space) to get the cpu revision ? I know that I can read it from /proc/cpuinfo file but I'm curious if there is any function ?
Emil,

there is nothing for userspace to get the value at runtime
you could use the __SILICON_REVISION__ define to see what version you're compiling for

well, from userspace, you could use the debug mmrs interface to get at the ID MMRs.
find /sys/kernel/debug/blackfin/ -name CHIPID -o -name DSPID
but this is really only meant for development systems and not for deploying in production ... not sure why you want this information
