QCOM SPI NAND driver got merged upstream hence we can drop the special patch from qualcommax and qualcommbe target and move them to the generic backports directory to reduce patch maintenance. While at it refresh any affected patch and target and also backport other minor fixup for the SPI NAND driver merged upstream later.

Subject: [PATCH 17/20] spi: add support for sf21-qspi
|
|
|
|
Add support for the QSPI controller found on Siflower SF21A6826
|
|
and SF21H8898.
|
|
It is based on ARM PL022, with custom modifications to support
|
|
Dual/Quad SPI modes.
|
|
A new driver is created because this modified controller is
|
|
supported under the SPI-MEM framework. While the setup procedure
|
|
is a bit similar to the spi-pl022.c, there aren't much code
|
|
shared between them.
