2017-09-25driver: mtd: update struct map_info's swap as per map requirementAlison Wang
It is not necessary for all device's maps to be CFI_HOST_ENDIAN. Maps device can be big endian or little endian. Currently it is being taken care using CONFIG_MTD_CFI_LE_BYTE_SWAP or CONFIG_MTD_CFI_BE_BYTE_SWAP i.e. compile time.

2017-09-25mtd: spi-nor: add a stateless method to support memory size above 128MibCyrille Pitchen
This patch provides an alternative mean to support memory above 16MiB (128Mib) by replacing 3byte address op codes by their associated 4byte address versions. Using the dedicated 4byte address op codes doesn't change the internal state of the SPI NOR memory as opposed to using other means such as updating a Base Address Register (BAR) and sending command to enter/leave the 4byte mode. Hence when a CPU reset occurs, early bootloaders don't need to be aware of BAR value or 4byte mode being enabled: they can still access the first 16MiB of the SPI NOR memory using the regular 3byte address op codes.

2017-09-25mtd: spi-nor: rename SPINOR_OP_* macros of the 4-byte address op codesAlison Wang
This patch renames the SPINOR_OP_* macros of the 4-byte address instruction set so the new names all share a common pattern: the 4-byte address name is built from the 3-byte address name appending the "_4B" suffix. The patch also introduces new op codes to support other SPI protocols such as SPI 1-4-4 and SPI 1-2-2. This is a transitional patch and will help a later patch of spi-nor.c to automate the translation from the 3-byte address op codes into their 4-byte address version.

2017-09-25mtd: spi-nor: remove WARN_ONCE() message in spi_nor_write()Cyrille Pitchen
This patch removes the WARN_ONCE() test in spi_nor_write(). This macro triggers the display of a warning message almost every time we use a UBI file-system because a write operation is performed at offset 64, which is in the middle of the SPI NOR memory page. This is a valid operation for ubifs. Hence this warning is pretty annoying and useless so we just remove it.

A-009282: QuadSPI: QuadSPI data pre-fetch can result in incorrect data Affects: QuadSPI Description: With AHB buffer prefetch enabled, the QuadSPI may return incorrect data on the AHB interface. The buffer pre-fetch is enabled if the fetch size as configured either in the LUT or in the BUFxCR register is greater than 8 bytes. Impact: Only 64 bit read allowed.
