From 99c62dd773797b68f3b1ca6bb3274725d1852fa2 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 16 Apr 2008 05:52:21 +1000 Subject: [POWERPC] Remove and replace uses of PPC_MEMSTART with memstart_addr A number of users of PPC_MEMSTART (40x, ppc_mmu_32) can just always use 0 as we don't support booting these kernels at non-zero physical addresses since their exception vectors must be at 0 (or 0xfffx_xxxx). For the sub-arches that support relocatable interrupt vectors (book-e), it's reasonable to have memory start at a non-zero physical address. For those cases use the variable memstart_addr instead of the #define PPC_MEMSTART since the only uses of PPC_MEMSTART are for initialization and in the future we can set memstart_addr at runtime to have a relocatable kernel.
