| Subject: ARM: shmobile: Lager: set proper DMA masks for Ether device |
| |
| Ether MAC is a DMA-capable device and so should have 'dev.dma_mask' and |
| 'dev.coherent_dma_mask' fields set properly, to reflect 32-bit DMA addressing |
| ability. |
| |
| Currently, the code works without DMA masks but as we would have to enable |
| CONFIG_HIGHMEM to access the full board memory in the future, when support for |
| NETIF_F_SG would be added to the 'sh_eth' driver as well, the correct DMA masks |
| should start to matter... |
