The intention has always been (and boards are to support) an i2c EEPROM
that will identify what hardware they are, allowing a single binary to
support multiple boards. As such, remove the 'evm.c' file as there is
nothing EVM centric in it currently, only SoC peripheral configuration.
Hey all,
The following series depends on both Ilya's cpsw work (the parts I've
said I would accept as-is) as well as the previous series I posted.
This series does a few things. The main part is support for the next TI
EVM (AM335x StarterKit EVM) which features DDR3 and re-works the board.c
am33xx boards have at least one eeprom and in the case of beaglebones
with capes, more.
