From: Fabio Estevam Date: Thu, 5 Nov 2015 14:43:40 +0000 (-0200) Subject: powerpc: Remove __ilog2_u64 and ffs4 from bitops X-Git-Tag: v2016.01-rc1~90 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2d2f490d;p=u-boot powerpc: Remove __ilog2_u64 and ffs4 from bitops Remove __ilog2_u64 and ffs4 from powerpc bitops to align with the kernel implementation. Use the generic __ffs64 instead of a custom powerpc implementation.
