From: Magnus Damm Date: Wed, 5 Feb 2014 05:36:28 +0000 (+0900) Subject: ARM: shmobile: Use 64-bit dma_addr_t on r8a7790/r8a7791 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4a51856b42672cfcb7d6fbab22dcf2caba2be5ab;p=linux-beck.git ARM: shmobile: Use 64-bit dma_addr_t on r8a7790/r8a7791 Some on-chip devices on r8a7790 and r8a7791 can do bus mastering and access more than 32-bits of address space. Select ARCH_DMA_ADDR_T_64BIT when LPAE is set in case of multiplatform and legacy SoC support.
