Subject: [PATCH] ARM: shmobile: Use 64-bit dma_addr_t on r8a7790/r8a7791
Date: Wed, 05 Feb 2014 05:36:28 +0000 [thread overview]
Message-ID: <20140205053628.29078.92360.sendpatchset@w520> (raw)
From: Magnus Damm <damm@opensource.se>
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.
