2006-07-28PPC440 DDR setup: Set SDRAM0_CFG0[PMU]=0 for best performanceStefan Roese
AMCC suggested to set the PMU bit to 0 for best performace on the PPC440 DDR controller. Please see doc/README.440-DDR-performance for details. Patch by Stefan Roese, 28 Jul 2006

2006-03-31Updates to common PPC4xx onboard (DDR)SDRAM init code (405 and 440)Stefan Roese
405 SDRAM: - The SDRAM parameters can now be defined in the board config file and the 405 SDRAM controller values will be calculated upon bootup (see PPChameleonEVB). When those settings are not defined in the board config file, the register setup will be as it is now, so this implementation should not break any current design using this code. Thanks to Andrea Marson from DAVE for this patch. 440 DDR: - Added function sdram_tr1_set to auto calculate the TR1 value for the DDR. - Added ECC support (see p3p440).

2005-11-22Add support for Prodrive P3P440 board:Stefan Roese
- Added onboard PPC440 DDR autodetection in cpu/ppc/sdram.c - CFG_FLASH_QUIET_TEST added to use the common CFI driver for bank autodetection Patch by Stefan Roese, 22 Nov 2005

2003-06-27* Code cleanup:wdenk
- remove trailing white space, trailing empty lines, C++ comments, etc. - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c) * Patches by Kenneth Johansson, 25 Jun 2003: - major rework of command structure (work done mostly by Michal Cendrowski and Joakim Kristiansen)
