From 4e7f72660c39a81cc5745d5c6f23f9500f80d8d8 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 15 Aug 2013 11:28:30 +0200 Subject: MIPS: Remove unnecessary platform dma helper functions The semantics stay the same - on Cavium Octeon the functions were dead code (it overrides the MIPS DMA ops) - on other platforms they contained no code at all.
