* driver/ddr/fsl: Add DDR4 support to Freescale DDR driverYork Sun2014-04-221-4/+22
| | | | | | | Mostly reusing DDR3 driver, this patch adds DDR4 SPD handling, register calculation and programming. Signed-off-by: York Sun <yorksun@freescale.com>
* driver/ddr: Add 256 byte interleaving supportYork Sun2014-02-211-0/+3
| | | | | | | Freescale LayerScape SoCs support controller interleaving on 256 byte size. This interleaving is mandoratory. Signed-off-by: York Sun <yorksun@freescale.com>

| | | | | | | | | endian Initially it was believed the DDR controller on Freescale ARM would have big endian. But some platform will have little endian. Signed-off-by: York Sun <yorksun@freescale.com>
* Driver/DDR: Add Freescale DDR driver for ARMYork Sun2013-11-251-0/+4
| | | | | | | Make PowerPC specific code conditional so ARM SoCs can reuse this driver. Add DDR3 driver for ARM. Signed-off-by: York Sun <yorksun@freescale.com>
* Driver/DDR: combine ccsr_ddr for 83xx, 85xx and 86xxYork Sun2013-11-251-1/+3
| | | | | | | Fix ccsr_ddr structure to avoid using typedef. Combine DDR2 and DDR3 structure for 83xx, 85xx and 86xx. Signed-off-by: York Sun <yorksun@freescale.com>
* Driver/DDR: Moving Freescale DDR driver to a common driverYork Sun2013-11-251-0/+265
Freescale DDR driver has been used for mpc83xx, mpc85xx, mpc86xx SoCs. The similar DDR controllers will be used for ARM-based SoCs. Signed-off-by: York Sun <yorksun@freescale.com>
