From: Marek Vasut Date: Mon, 24 Oct 2011 23:41:42 +0000 (+0000) Subject: DEBUG: Fix debug macros X-Git-Tag: v2011.12-rc1~345 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=88a85fb9f3578f513d7053ac9a3f1ff7521b2771;p=u-boot DEBUG: Fix debug macros The current implementation of debug doesn't play well with GCC4.6. This implementation also fixes GCC4.6 complaints about unused variables while maintaining code size. Also, drop the debugX() as that's not used anywhere anymore.
