AM335x-based 'Gumstix Pepper' SBCs and variants use different types of
RAM (DDR2 vs DDR3 with DDR3 being the default). Detect the board type
by reading the factory-programmed EEPROM [1] and use this to select any
runtime boot options such as RAM type.

Use "_ethaddr" at the end of variables and drop CamelCase.

As noted by clang, we have been shifting certain values out of 32bit
range when setting some DDR registers. Upon further inspection these
had been touching reserved fields (and having no impact). These came in
from historical bring-up code and can be discarded. Similarly, we had
been declaring some fields as 0 when they will be initialized that way.
Tested on Beaglebone White.
