From a1a9843a29672be49a5bbb3a07fea8dbc88369ba Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 20 Nov 2019 22:36:24 +0100 Subject: ARM: socfpga: Unreset NAND in SPL on Gen5 In case the SPL on Gen5 loads U-Boot from NAND, unreset the NAND IP explicitly in the platform code as the denali-spl driver is not aware of DM at all.
