784ab7c545 OMAP5: EMIF: Add support for DDR3 device
In OMAP5432 EMIF controlller supports DDR3 device.
This patch adds support for ddr3 device intialization and configuration.
Initialization sequence is done as specified in JEDEC specs.
This also adds support for ddr3 leveling.

aaec44874f OMAP4/5: emif: Correct the emif power mgt shadow register bit fields.
PD_TIM bit field which specifies the power down timing is defined
to occupy bits 8-11, where as it is actually from 12-15 bits.
So correcting this.

f40107345c OMAP5: emif/ddr: Change emif settings as required for ES1.0 silicon.
The OMAP5 silicon has new DDR PHY design, which includes a external PHY
as well. So configuring the ext PHY parameters here. Also the EMIF timimg
registers and a couple of DDR mode registers needs to be updated based on
the testing from the actual silicon.

bb772a5944 omap5: emif: Add emif/ddr configurations required for omap5 evm
Add the emif configurations required for omap5 soc.Add the
correct ddr part configurations required for omap5 evm board.
EDB8164B3PH from ELPIDA is the part used on the board.

Also changes are done to retain some part of the code
common for OMAP4/5 and keep only the remaining in the Soc
specific directories.
