2011-04-04powerpc/8xxx: Refactor fsl_ddr_get_spd into common code from boardKumar Gala
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.

2011-01-198xxx/ddr: add support to only compute the ddr sdram sizeHaiying Wang
This patch adds fsl_ddr_sdram_size to only calculate the ddr sdram size, in case that the DDR SDRAM is initialized in the 2nd stage uboot and should not be intialized again in the final stage uboot.

2011-01-14MPC8xxx DDR: align informational printsBecky Bruce
Add spaces to cause the informational prints to line up with the ones from init_func_ram() in board.c. Output now looks like this: .... DRAM: Detected 4096 MB of memory This U-Boot only supports < 4G of DDR You could rebuild it with CONFIG_PHYS_64BIT DDR: 2 GiB (DDR2, 64-bit, CL=5, ECC off) .... The prints from lbc_sdram_init() have also been modified to line line up and changed to start with "LBC SDRAM" instead of the confusing "SDRAM".

2010-07-26powerpc/8xxx: Fix bug in memctrl interleaving & bank interleaving on cs0~cs4york
Verified on MPC8641HPCN with four DDR2 dimms. Each dimm has dual rank with 512MB each rank. Also check dimm size and rank size for memory controller interleaving Signed-off-by: York Sun <yorksun@freescale.com>
2010-04-21Move arch/ppc to arch/powerpcStefan Roese
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
