From 0c350a9a5cf01db3875ceb8b01121d8ce6a7f287 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Tue, 21 Feb 2012 13:53:15 -0600 Subject: [PATCH] powerpc/85xx: allow CONFIG_PHYS_64BIT to be selectable Remove the "select PHYS_64BIT" from the Kconfig entry for the P1022DS, so that large physical address support is a selectable option for non-CoreNet reference boards. The option is enabled in mpc85xx_[smp_]defconfig so that the default is unchanged. However, now it can be deselected. The P1022DS had this option defined because the default device tree for this board uses 36-bit addresses. This had the side-effect of forcing this option on for all boards that use mpc85xx_[smp_]defconfig. Some users may want to disable this feature to create an optimized configuration for boards with <= 2GB of RAM.
