From dd82128ef5e9fc660862a0a60423aa01a03de5d4 Mon Sep 17 00:00:00 2001 From: Daniel Schwierzeck Date: Sun, 18 Jan 2015 22:18:38 +0100 Subject: MIPS: add support for CONFIG_SYS_INIT_SP_ADDR Support the existing config option CONFIG_SYS_INIT_SP_ADDR on MIPS. This allows to move the initial stack to other places than the beginning of RAM.
