From 7a3e0f74a7c3ff83ba0607ebf8a14310ff08db60 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Mon, 26 Sep 2016 19:28:56 +0100 Subject: [PATCH] MIPS: Use ram_top, not bi_memsize, in arch_lmb_reserve When calculating the region to reserve for the stack in arch_lmb_reserve, make use of ram_top instead of adding bi_memsize to CONFIG_SYS_SDRAM_BASE. This avoids overflow if the system has enough memory to reach the end of the address space.
