-Subject: [PATCH 104/113] mtd: fsl-quadspi: Add quad mode for flash n25q128
-
-Add some lut_tables to support quad mode for flash n25q128
-on the board ls1021a-twr and solve flash Spansion and Micron
-command conflict.
-In switch {}, The value of command SPINOR_OP_RD_EVCR and
-SPINOR_OP_SPANSION_RDAR is the same. They have to share
-the same seq_id: SEQID_RDAR_OR_RD_EVCR.
