From e40d8067fe8ef7c59184d508373e9cca22c911fe Mon Sep 17 00:00:00 2001 From: Liu Xiang Date: Tue, 28 Aug 2018 22:32:57 +0800 Subject: [PATCH] mtd: spi-nor: fsl-quadspi: fix read error for flash size larger than 16MB commit 41fe242979e463d6ad251077ded01b825a330b7e upstream. If the size of spi-nor flash is larger than 16MB, the read_opcode is set to SPINOR_OP_READ_1_1_4_4B, and fsl_qspi_get_seqid() will return -EINVAL when cmd is SPINOR_OP_READ_1_1_4_4B. This can cause read operation fail.
