From 3cf29543413207d3ab1c3f62a88c09bb46f2264e Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 7 Apr 2015 13:34:02 -0700 Subject: [PATCH] MIPS: BCM63xx: Provide a plat_post_dma_flush hook Broadcom BCM63xx DSL SoCs utilize BMIPS CPUs, and as such are required to perform a read-ahead cache flush after a DMA transfer. Utilize asm/bmips.h to provide a plat_post_dma_flush_hook, and mach-generic/dma-coherence.h for everything else.
