Hello,

I have seen it a common practice to assume low RAM as source 
of good parity data and use it to fill the caches with good parity 
data in firmware during elementary hardware initialisation process.

why it is always safe to assume that low RAM contains good parity data .?
Is it always true..?
this question came in picture after I got cacheparity error sometimes.

Best Regards,
Ashish Anand
