From: Po-Yu Chuang Date: Tue, 1 Mar 2011 23:02:04 +0000 (+0000) Subject: arm: fix incorrect monitor protection region in FLASH X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f326cbb;p=project%2Fbcm63xx%2Fu-boot.git arm: fix incorrect monitor protection region in FLASH Monitor protection region in FLASH did not cover .rel.dyn and .dynsym sections, because it uses __bss_start to compute monitor_flash_len. Use _end instead. Add _end to linker scripts for end of u-boot image Add _end_ofs to all the start.S.
