U-Boot has been broken on Overo boards since commit
a6b541b090.
This is because the gd pointer is not set early enough anymore,
such that the i2c_set_bus_num in get_board_revision can safely
execute. This results in a console hang at SPL and the boot does
not proceed.
This piece of code is anyway necessary only for really old Overo
boards with revision numbers <= 2410 and not required for the newer
boards. For these older boards, u-boot v2014.10 still works fine.

This separates the SPL-specific code from the u-boot-specific code for
the Overo board following the discussion at
http://lists.denx.de/pipermail/u-boot/2015-April/211622.html
The code is split up into spl.c, overo.c and common.c (which
has the code common to both)
