Gregory Nutt d3beea967d Cortex-M7: Add support for enabled the D-Cache in write only mode. SAMV7 Ethernet: I- and D-Cache are now enabled in the netnsh/ configuration. D-Cache is enabled in write-though mode. This mode is necessary because the DMA descriptors are each 8-bytes in size but the D-Cache cache line is 32-bits in size. So it is impossible make coherency for every 8-byte DMA descriptor without write-through.	2015-03-29 14:42:03 -06:00
