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. Signed-off-by: Vignesh R <vigneshr@ti.com> Reviewed-by: Jagan Teki <jteki@openedev.com>
