Marcin Wojtas ac5f0f3f86 dmaengine: mv_xor: add support for Armada 3700 SoC ... Armada 3700 SoC comprise a single XOR engine compliant with the ones used in older Marvell SoC's like Armada XP or 38x. The only thing that needs modification is the Mbus configuration, which has to be done on two levels: global and in device. The first one is inherited from the bootloader. The latter can be opened in a default way, leaving arbitration to the bus controller. Hence filled mbus_dram_target_info structure is not needed. Patch "dmaengine: mv_xor: optimize performance by using a subset of the XOR channels" introduced limitation for using XOR engines and channels vs number of available CPU's. Those constraints do not however fit Armada 3700 architecture with two possible CPU's and single, dual-channel engine. Hence in this commit an adjustment for setting maximum available channels is added. This patch enables XOR access to DRAM by opening default window to 4GB space with specific attribute.
