u-boot.git/board/ml2/init.S, branch v2009.06 Unnamed repository; edit this file 'description' to name the repository. ppc4xx: Remove superfluous dram_init() call or replace it by initdram() 2008-06-03T18:22:19+00:00 Stefan Roese sr@denx.de 2008-06-02T15:37:28+00:00 bbeff30cbd1c5d551eb0ad1c2239ec01844c0b0a Historically the 405 U-Boot port had a dram_init() call in early init stage. This function was still called from start.S and most of the time coded in assembler. This is not needed anymore (since a long time) and boards should implement the common initdram() function in C instead. This patch now removed the dram_init() call from start.S and removes the empty implementations that are scattered through most of the 405 board ports. Some older board ports really implement this dram_init() though. These are: csb272 csb472 ERIC EXBITGEN W7OLMC W7OLMG I changed those boards to call this assembler dram_init() function now from their board specific initdram() instead. This *should* work, but please test again on those platforms. And it is perhaps a good idea that those boards use some common 405 SDRAM initialization code from cpu/ppc4xx at some time. So further patches welcome here. Signed-off-by: Stefan Roese <sr@denx.de>
