2007-02-20[PATCH] PPC4xx: Split 4xx SPD SDRAM init routines into 2 filesStefan Roese
Since the existing 4xx SPD SDRAM initialization routines for the 405 SDRAM controller and the 440 DDR controller don't have much in common this patch splits both drivers into different files. This is in preparation for the 440 DDR2 controller support (440SP/e). Signed-off-by: Stefan Roese <[email protected]>
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

Add support for Motorola MPC8266ADS board * Patch by Kyle Harris, 19 Feb 2003: patches for the Intel lubbock board: memsetup.S - general cleanup (based on Robert's csb226 code) flash.c - overhaul, actually works now lubbock.c - fix init funcs to return proper value * Patch by Kenneth Johansson, 26 Feb 2003: - Fixed off by one in RFTA calculation. - No need to abort when LDF is lower than we can program it's only minimum timing so clamp it to what we can do. - Takes function pointer to function for reading the spd_nvram. Usefull for faking data or hardcode a module without the nvram. - fix other user for above change - fix some comments. * Patches by Brian Waite, 26 Feb 2003: - fix port for evb64260 board - fix PCI for evb64260 board - fix PCI scan * Patch by Reinhard Meyer, 1 Mar 2003: Add support for EMK TOP860 Module * Patch by Yuli Barcohen, 02 Mar 2003: Add SPD EEPROM support for MPC8260ADS board
