From: Masahiro Yamada Date: Thu, 11 Jun 2015 10:16:43 +0000 (+0900) Subject: blackfin: fix undefined reference to srand and rand X-Git-Tag: v2015.07-rc3~91 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=3850dbe833facceb5b3d57a6a0ee93532b445aaa;p=u-boot blackfin: fix undefined reference to srand and rand Commit 9ba9e85f3f1c (net: Fix NET_RANDOM_ETHADDR dependencies) accidentally dropped CONFIG_LIB_RAND defines for 14 Blackfin boards. Prior to that commit, those boards defined CONFIG_LIB_RAND, but not CONFIG_NET_RANDOM_ETHADDR. So, commit 9ba9e85f3f1c should not have touched them, but in fact it ripped CONFIG_LIB_RAND off from all the header files, which caused undefined reference to srand and rand. CONFIG_LIB_RAND=y must be revived for such boards. BTW, this commit indeed makes it better, but even with this fix, three boards (bf533-stamp, bf538f-ezkit, cm-bf548) still can not build due to region 'ram' overflowed error. This was cause by commit 6eed3786c68c (net: Move the CMD_NET config to defconfigs) because CMD_NET selects NET, and NET selects REGEX. Eventually, some boards were newly enabled with CONFIG_REGEX, increasing the memory footprint. A patch is expected to fix the build error.
