From: Mike Nuss Date: Mon, 5 Oct 2009 16:33:28 +0000 (-0400) Subject: PPC4xx: Denali core: Fix incorrect DDR row bits X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=54f5f056aa1daa3e39bad1c5c3fb43a72cdb9e84;p=project%2Fbcm63xx%2Fu-boot.git PPC4xx: Denali core: Fix incorrect DDR row bits The SPD detection code for the Denali memory controller used on some ppc4xx processors incorrectly encodes DDR0_42. With certain memory configurations, this can cause the bootwrapper to incorrectly calculate the installed memory size, because the number of row bits is wrong. This patch fixes that encoding.
