Hello David & all,
Thank you for the information. We're trying this
sreadahead(http://code.google.com/p/sreadahead/) on ARM based target. As
these __sync_fetch_and_add_4 & readahead are not part of bionic libc; could
you please suggest us any alternatives. Or any other technique to reduce
bootup time ?
Thanks.

Googling reveals that __sync_fetch_and_add_4 is an x86 and x86_64
