From fc5e22008a668a75d108ebf8edc93849c6f9dcb4 Mon Sep 17 00:00:00 2001 From: Vignesh R Date: Mon, 17 Aug 2015 13:29:57 +0530 Subject: ARM: dra7xx_evm: Enable EDMA3 in SPL to support DMA on qspi Enable TI_EDMA3 and SPL_DMA support, so as to reduce boot time. With DMA enabled there is almost 3x improvement in read performance. This helps in reducing boot time in qspiboot mode Also add EDMA3 base address for DRA7XX and AM57XX.
