From: York Sun Date: Wed, 25 Nov 2015 22:56:40 +0000 (-0800) Subject: armv8: fsl-layerscape: Fix early MMU table for nand boot X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3785f57015dbd7582f85fd1c34dcaa26638bf976;p=u-boot.git armv8: fsl-layerscape: Fix early MMU table for nand boot The early MMU table doesn't enable all addresses. Unused addresses are marked as invalid, as introduced by commit 9979922. An entry was missing for NAND flash space, causing nand boot failure.
