From 6e1551a870d360805b9d172dc56d935064abe71d Mon Sep 17 00:00:00 2001 From: Andrew Dyer Date: Fri, 12 Sep 2008 02:20:46 +0200 Subject: [PATCH] arm920t fix constant error in start.S Code in cpu/arm920t/start.S will die with a compilation error if CONFIG_STACKSIZE + CFG_MALLOC_LEN works out to an invalid constant for the ARM sub instruction. Change the code so that each is subtracted independently to avoid the error.
