* powerpc/mpc8xxx: Merge entries in DDR speed tableYork Sun2011-10-09-28/+50
| | | | | | | | | | | | | | | It is not necessary to keep multiple entries for the same setting in DDR speed tables. Merge them for smaller tables. Also restructure the tables for smaller size. Cleanup some typedefs. Enforce strict checking for speed table. If DIMM is running at higher than known speed, try to use the highest speed setting. If rank is unknown, it has to panic. Removed ODT overriding for P2020DS as it is not necessary. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/p2041rdb: add more ddr frequencies supportShaohui Xie2011-10-03-1/+4
| | | | | | | | | This table covers DDR frequencies from 666 to 1666. Frequencies 666, 833, 1000, 1066 and 1333 were verified on this board with SO-DIMM (UG51U6400N8SU-ACF). Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* MPC8xxx: drop redundant boot messagesWolfgang Denk2011-07-29-1/+1
| | | | | | | | | | | | | | | Current code would print RAM size information like this: DRAM: DDR: 256 MiB (DDR1, 64-bit, CL=2, ECC off) Turn a number of printf()s into debug() to get rid of the redundant "DDR: " string like this: DRAM: 256 MiB (DDR1, 64-bit, CL=2, ECC off) Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
