From: Pali Rohár Date: Mon, 25 Apr 2022 03:59:08 +0000 (+0530) Subject: powerpc: mpc85xx: Drop _start symbol X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-logo.png?a=commitdiff_plain;h=2dcf776ebcf7f224f2a2e6720e863aca493a5cd9;p=u-boot.git powerpc: mpc85xx: Drop _start symbol _start symbol contains only 32-bit data number 0x27051956 despite it is marked as text section. This magic number is IH_MAGIC which is used for marking uboot image header. mpc85xx start.S code does not define valid uboot image header, so IH_MAGIC number in _start symbol is useless there. Moreover this _start symbol is not used at all. Entry point is at symbol _start_e500. So because this _start symbol is not used for anything, completely remove it with IH_MAGIC number. After _start symbol was _start_cont symbol, so replace all relative address calculations by _start_cont.
