Add DDR3 support for AM335x-EVM (Version 1.5A)
AM335x EVM 1.5A uses Micron MT41J512M8RH-125 SDRAM 4Gb (512Mx8) as the
DDR3 chip.
[Hebbar Gururaja <gururaja.hebbar@ti.com>]
- Resolve merge conflict while rebasing. File structure is
changed in the mainline. So re-arrange the code accordingly.
- Update commit message to reflect the DDR3 part number
