* Driver/DDR: Moving Freescale DDR driver to a common driverYork Sun2013-11-25-2/+2
| | | | | | | 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>
* powerpc/8xxx: Refactor fsl_ddr_get_spd into common code from boardKumar Gala2011-04-04-21/+0
| | | | | | | | | | | | | | Move fsl_ddr_get_spd into common mpc8xxx/ddr/main.c as most boards pretty much do the same thing. The only variations are in how many controllers or DIMMs per controller exist. To make this work we standardize on the names of the SPD_EEPROM_ADDRESS defines based on the use case of the board. We allow boards to override get_spd to either do board specific fixups to the SPD data or deal with any unique behavior of how the SPD eeproms are wired up.

* powerpc/8xxx: Replace fsl_ddr_get_mem_data_rate with get_ddr_freq()Kumar Gala2011-04-04-5/+0
| | | | | | | | | | Every 85xx board implements fsl_ddr_get_mem_data_rate via get_ddr_freq() and every 86xx board uses get_bus_freq(). If implement get_ddr_freq() as a static inline to call get_bus_freq() we can remove fsl_ddr_get_mem_data_rate altogether and just call get_ddr_freq() directly.

* Pass dimm parameters to populate populate controller optionsHaiying Wang2008-10-18-1/+4
| | | | | | | | | | | | | Because some dimm parameters like n_ranks needs to be used with the board frequency to choose the board parameters like clk_adjust etc. in the board_specific_paramesters table of the board ddr file, we need to pass the dimm parameters to the board file. * move ddr dimm parameters header file from /cpu to /include directory. * add ddr dimm parameters to populate board specific options. * Fix fsl_ddr_board_options() for all the 8xxx boards which call this function.
