font-family:Arial'>How should one define CFG_HZ? It seems that it’s
to be set to 1000. However my system clock speed is not this. What
are the rules for setting this value? This constant is used in the timing
functions of some boards. I am working on implementing the timing
functions and have a hard time understanding how this could be the same across
all boards. I have a timer on my board that I’d like to use to
check for timeout conditions for an SPI Controller driver. I have adapted
the timing functions in cpu/arm926ejs/omap/timer.c, but there also CFG_HZ is
used. Should I replace the CFG_HZ with my real system clock speed? BTW,
I have to read a register at boot time to determine what speed I am running
at. I do this early on and save a variable ‘clock_speed’ that
other functions can use to determine the system clock speed.</span></font></p>
