From 081a51c937952b91957873badafa11ad2a025315 Mon Sep 17 00:00:00 2001 From: Andy Yan Date: Tue, 26 Nov 2019 21:15:38 +0800 Subject: [PATCH] rockchip: rk3308: enable spl-fifo-mode for emmc We need load some parts of ATF to sram, but rockchip dwmmc controllers can't do dma to non-ddr addresses space, so set the mmc controller into fifo mode in spl. And show my best respect to Heiko's work for this solution.
