driver/ddr/fsl: Fix driver to support empty first slot

2015-04-23T15:55:53Z

CS0 was not allowed to be empty by u-boot driver in the past to simplify the driver. This may be inconvenient for some debugging. This patch lifts the restrictions. Controller interleaving still requires CS0 populated. Signed-off-by: York Sun

drivers/ddr/fsl: Update DDR driver for DDR4

2015-04-23T15:55:53Z

Add/update registers for DDR4, including DQ mappings. Allow raw timing method used for all controllers. Update mode_9 register to 0x500 for improved stability. Check DDR controller version number individually in case a SoC has multiple DDR controllers of different versions. Increase read-write turnaround for DDR4 high speeds. Signed-off-by: York Sun

driver/ddr/fsl: Fix tXP and tCKE

2014-09-25T15:36:18Z

The driver was written using old DDR3 spec which only covers low speeds. The value would be suboptimal for higher speeds. Fix both timing according to latest DDR3 spec, remove tCKE as an config option. Signed-off-by: York Sun

driver/ddr/fsl: Add support of overriding chip select write leveling

2014-09-08T17:30:34Z

JEDEC spec allows DRAM vendors to use prime DQ for write leveling. This is not an issue unless some DQ pins are not connected. If a platform uses regular DIMMs but with reduced DDR ECC pins, the prime DQ may end up on those floating pins for the second rank. The workaround is to use a known good chip select for this purpose.

driver/ddr/fsl: Fix printing unspecified module info for DDR4

2014-06-05T20:45:07Z

The offset of module information is at 128, different from DDR3. Signed-off-by: York Sun

Add cli_ prefix to readline functions

This makes it clear where the code resides. Signed-off-by: Simon Glass

move CLI prototypes to cli.h and add comments

2014-05-29T21:45:31Z

Move the CLI prototypes from common.h to cli.h as part of an effort to reduce the size of common.h. Signed-off-by: Simon Glass

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: 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
