From ff7ca5cb54ee9d0a2afeb1a3e99e091973d25d47 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Fri, 10 Apr 2015 18:41:58 +0300 Subject: [PATCH] arc: make sure _start is in the beginning of .text section This is important to have entry point in the beginning of .text section because it allows simple loading and execution of U-Boot. For example pre-bootloader loads U-Boot in memory starting from offset 0x81000000 and then just jumps to the same address. Otherwise pre-bootloader would need to find-out where entry-point is. In its turn if it deals with binary image of U-Boot there's no way for pre-bootloader to get required value.
