There were a number of shared files that were using CONFIG_SYS_MPC85xx_DDR_ADDR, or CONFIG_SYS_MPC86xx_DDR_ADDR, and several variants (DDR2, DDR3). A recent patchset added 85xx-specific ones to code which was used by 86xx systems. After reviewing places where these constants were used, and noting that the type definitions of the pointers assigned to point to those addresses were the same, the cleanest approach to fixing this problem was to unify the namespace for the 85xx, 83xx, and 86xx DDR address definitions. This patch does: s/CONFIG_SYS_MPC8.xx_DDR/CONFIG_SYS_MPC8xxx_DDR/g All 85xx, 86xx, and 83xx have been built with this change.
