This flash, mt35xu512aba, is only complaint to SFDP JESD216B and does not seem to support newer JESD216C standard that provides auto detection of Octal mode capabilities and opcodes. Therefore, this capability is manually added using new SPI_NOR_OCTO_READ flag. Signed-off-by: Vignesh R Signed-off-by: Yogesh Gaur --- Changes for v3: - Modified string 'octal' with 'octo'.
