From b5ee9002583fc14e6d45a04c18f208987a8fbced Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Fri, 5 Sep 2008 21:53:30 -0400 Subject: [ARM] remove a common set of __virt_to_bus definitions Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.
