it's CONFIG_SYS and magic number, but now that I've found it, sorry, I
can't accept this - not all 83xx have a QE and thus this MURAM.  Even
if they did this would require changing the device tree muram node
property, to indicate its size has shrunk 8 bytes, right?  In fact, not
all QE's have 48Kbytes of MURAM either - the 8323 only has 16Kbytes.  
Problem is, I don't know of a better place to put the
bootcount.  Ideas?
