Comment (by hailfinger):

 For timing tests of flash readout, make sure CPU frequency scaling and
 power management are disabled. Then run

 time flashrom -V --read test.rom; md5sum test.rom

 on an idle system a few times in a row. If the "delay loops per second"
 value varies a lot, either the system is under load or CPU frequency
 scaling is active. If the md5sum is not constant, something fishy is going

 The real/user/sys time needed for the command is what I'm interested in.
 The delay loop value is useless for LPC bus frequency measurement.
