[Patch v5 0/7] Transition of fsl qspi driver to spi-mem framework

[Kuldeep Singh]

This entire patch series migrate freescale qspi driver to spi-mem
framework.

Patch 1 adds new qspi driver incorporating spi-mem framework and also
removal of old driver which was based on spi-nor. The driver is a ported
version of linux qspi driver. Initial port was done by Frieder. Now, no
more direct memory access to spi-nor memory is possible i.e accessing flash
memory using absolute address is not possible.

Patch 2 removes unused qspi config options for layerscape platforms.

Patch 3 removes unused qspi config options for imx platforms.

Patch 4 moves FSL_QSPI to defconfig instead of defining it in header files.

Patch 5 enables SPI_FLASH_SPANSION in ls1012a defconfig as FSL_QSPI is
already enabled.

Patch 6 enables SPI_FLASH_SPANSION in defconfigs of LS1046a boards instead
of defining in header files.

Patch 7 updates the device-tree properties treewide for layerscape boards
by aligning with linux device-tree properties.

v5:
-Remove compilation warning/error in patch1(qspi driver).
-Split patch 2 into 2 patches as changes will go via different tree.
-Remove imx dts change(previusly patch 4) as superseeded by Fabio's patch.

v4:
-Removal of buildman failure on LS2080AQDS
-Reword commit message of patch 5.

v3:
-Correction of copyright in qspi driver(Patch 1).
-Move SPI_FLASH_SPANSION from header to defconfig in same patch.

v2:
-Incorporate 1k size to make driver independent of flash size.
-Add support for imx platforms to set TDH bits correctly.
-Reword commit messages.

Patch[1] is required to resolve booting crash observed in LS1012ARDB. Crash
was related to pfe driver as it was accessing flash memory directly.
