[PATCH 0/3] Enable octal read support for mt35xu* flashes
Patch series enable octal read(1-1-8) support for LX2160ARDB and LS1028ARDB which have mt35xu512aba and mt35xu02g flashes respectively.
mt35xu512aba and mt35xu02g flashes support SINGLE and OCTAL I/O. Previously, 1 bit mode was used in u-boot and now use octal mode for the flashes.
Also add RX and TX buswidth in qspi dts entry to use 1-1-8 mode. DTS entries can be merged once patch[1] is merged. No dependency on framework patch.

Commit "658df8bd9464"(mtd: spi-nor-core: Add octal mode support) enables octal mode(1-1-8) support in spi-nor framework.
mt35xu512aba and mt35xu02g flashes support SINGLE and OCTAL I/O. Hence, enable SPI_NOR_OCTAL_READ flag for the same.
