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 Signed-off-by: Jeff Lance <j-lance1@ti.com> Signed-off-by: Tom Rini <trini@ti.com> Signed-off-by: Hebbar Gururaja <gururaja.hebbar@ti.com>
