powerpc/mpc85xx: Add workaround for DDR erratum A004508

2014-06-05T20:45:07Z

When the DDR controller is initialized below a junction temperature of 0°C and then operated above a junction temperature of 65°C, the DDR controller may cause receive data errors, resulting ECC errors and/or corrupted data. This erratum applies to the following SoCs and their variants: MPC8536, MPC8569, MPC8572, P1010, P1020, P1021, P1022, P1023, P2020. Signed-off-by: York Sun

drivers/ddr: Fix possible out of bounds error

2014-04-23T00:58:49Z

This is a theoretical possible out of bounds error in DDR driver. Adding check before using array index. Also change some runtime conditions to pre-compiling conditions. Signed-off-by: York Sun Reviewed-by: York Sun

driver/ddr/fsl: Add DDR4 support to Freescale DDR driver

2014-04-23T00:58:48Z

Mostly reusing DDR3 driver, this patch adds DDR4 SPD handling, register calculation and programming. Signed-off-by: York Sun

driver/ddr: Add 256 byte interleaving support

2014-02-21T16:06:13Z

Freescale LayerScape SoCs support controller interleaving on 256 byte size. This interleaving is mandoratory. Signed-off-by: York Sun

driver/ddr: Change Freescale ARM DDR driver to support both big and little endian

2014-02-21T16:06:13Z

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

powerpc/mpc8xxx: Extend DDR registers' fields

2013-11-25T19:43:46Z

Some DDR registers' fields have expanded to accommodate larger values. These changes are backward compatible. Some fields are removed for newer DDR controllers. Writing to those fields are safely ignored. TIMING_CFG_2 register is fixed. Additive latency is added to RD_TO_PRE automatically. It was a misunderstanding in commit c360ceac.

Driver/DDR: combine ccsr_ddr for 83xx, 85xx and 86xx

2013-11-25T19:43:46Z

Fix ccsr_ddr structure to avoid using typedef. Combine DDR2 and DDR3 structure for 83xx, 85xx and 86xx. Signed-off-by: York Sun

Driver/DDR: Moving Freescale DDR driver to a common driver

2013-11-25T19:43:43Z

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
