Then please either mention this fact in the commit message (the current one does not say anything about 16 versus 32 bit mode), or realy drop the patch. > >> --- u-boot-mainline.orig/drivers/video/cfb_console.c 2009-10-19 > >> 13:17:14.582303087 +0200 > >> +++ u-boot-mainline/drivers/video/cfb_console.c 2009-10-19 > >> 13:17:29.406303158 +0200 > > > > Please use git-format-patch to create patches. > > Why? Do you have any problems to apply these patches? I personally > (still) prefer using quilt for patch stack management. git-format-patch provides index information, which allows for intelligent merges (i. e. the merge code can then find the patch base and do a rebase internally). With your patches this is impossible. Fell free to use quilt or any other tools for your own purposes, but for patch submission please prepare the patches using git-format-patch > >> +#else > >> + unsigned int i, *p; > >> + > >> + i = dev->winSizeX * dev->winSizeY; > >> + p = (unsigned int *)dev->frameAdrs; > >> + while (i--) > >> + *p++ = 0; > >> +#endif > > > > Why don't you use memset() here? > > Maybe to ensure that D32 accesses are performed. Anatolij might know? How should Anatolij know? It is you who added this code, right?
