2008-03-27ppc4xx: Enable ECC on LWMON5Stefan Roese
Since all ECC related problems seem to be resolved on LWMON5, this patch now enables ECC support. We have to write the ECC bytes by zeroing and flushing in smaller steps, since the whole 256MByte takes too long for the external watchdog. Signed-off-by: Stefan Roese <sr@denx.de>
2008-01-04PPC4xx: Use common code for LWMON5 board SDRAM supportLarry Johnson
This patch also modifies the functionality of the code so that the data-eye search is now done with with the cache disabled. Signed-off-by: Larry Johnson <lrj@acm.org>
2007-10-31ppc4xx: Consolidate some of the 405 and 440 macros/structs into 4xxStefan Roese
This patch moves some common 4xx macros and the PPC405_SYS_INFO/ PPC440_SYS_INFO structure into the common ppc4xx.h header. Lot's of other macros are good candidates to be consolidated this way in the future. Signed-off-by: Stefan Roese <sr@denx.de>
2007-08-18lib_ppc: make board_add_ram_info weakKim Phillips
platforms wishing to display RAM diagnostics in addition to size, can do so, on one line, in their own board_add_ram_info() implementation. this consequently eliminates CONFIG_ADD_RAM_INFO. Thanks to Stefan for the hint. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
