* powerpc/8xxx: Enabled address hashing for 85xxyork2010-07-26-2/+13
| | | | | | | For 85xx silicon which supports address hashing, it can be activated by hwconfig. Signed-off-by: York Sun <yorksun@freescale.com>
* powerpc/8xxx: Fix bug in memctrl interleaving & bank interleaving on cs0~cs4york2010-07-26-0/+3
| | | | | | | | | 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>
* powerpc/8xxx: Enabled hwconfig for memory interleavingKumar Gala2010-07-26-11/+14
| | | | | | | | | | | | | | | | | | | | | Replace environmental variables memctl_intlv_ctl and ba_intlv_ctl with hwconfig parameters. The syntax is setenv hwconfig "fsl_ddr:ctlr_intlv=<mode>,bank_intlv=<mode>" The mode values for memory controller interleaving are cacheline page bank superbank The mode values for bank interleaving are cs0_cs1 cs2_cs3 cs0_cs1_and_cs2_cs3 cs0_cs1_cs2_cs3 Signed-off-by: York Sun <yorksun@freescale.com>
* Check DDR interleaving modeHaiying Wang2008-10-18-0/+69
* Check DDR interleaving mode from environment by reading memctl_intlv_ctl and ba_intlv_ctl. * Print DDR interleaving mode information * Add doc/README.fsl-ddr to describe the interleaving setting Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com>
