It was this way in the original bootstrap version. I can remove it if you 
prefer.

No. Currently the implementation only checks strings and has no idea of 
frequencies. Also, not only PLL frequencies are configured in this I2C 
bootstrap EEPROM but also boot-location (NOR, NAND, PCI) and other things. So 
it's really not trivial to find/search the current configuration in this 
table.

Since 4xx prints the speed's in the bootlog, it shouldn't be too hard to find 
the current setting there (if necessary).

Ups. Will fix. Thanks.
