From: Yann E. MORIN Date: Thu, 11 Sep 2014 20:46:46 +0000 (+0200) Subject: arch/arc: fix atomics selection X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=21c8f1e9470d37787b6d7cef10612df56cfdef2a;p=buildroot.git arch/arc: fix atomics selection Due to a kconfig limitation, we can't select a no-prompt symbol that gets its dependencies by being conditionally re-defined in one or more if-blocks, like we currently do for BR2_ARCH_HAS_ATOMICS. As a workaround to this issue, we just redefine that symbol in the arc if-block, like we do for all other architectures, except that in the arc case, the default value is conditional.
