* [PATCH v2 29/29] scsi: ufs: Split the drivers/scsi/ufs directory

Cc: Jaegeuk Kim, Adrian Hunter, linux-scsi, Bart Van Assche
Split the drivers/scsi/ufs directory into a ufs-core and a ufs-drivers
directory. Move shared header files into the include/scsi directory.
This separation makes it clear which header files UFS drivers are allowed
to include (include/scsi/*.h) and which header files UFS drivers are not
allowed to include (drivers/scsi/ufs-core/*.h).
Update the MAINTAINERS file. Add myself as a UFS reviewer.

+ Universal Flash Storage (UFS) is SCSI transport specification for
+ accessing flash storage on digital cameras, mobile phones and
+ consumer electronic devices.
+ A UFS controller communicates with a UFS device by exchanging
+ UFS Protocol Information Units (UPIUs).
+ UPIUs can not only be used as a transport layer for the SCSI protocol
+ but are also used by the UFS native command set.
+ This transport driver supports exchanging UFS protocol information units
+ with a UFS device. See also the ufshcd driver, which is a SCSI driver

Thanks for the feedback. I will move this patch to a future patch series
such that it does not block merging of the previous patches in this series.
Thanks,

Bart,
Looks good to us, but we need to verify it on the two platforms, and
need some time before add reviewed and tested tag.

Split the drivers/scsi/ufs directory into a ufs-core and a ufs-drivers
directory. Move shared header files into the include/scsi directory.
This separation makes it clear which header files UFS drivers are allowed
to include (include/scsi/*.h) and which header files UFS drivers are not
allowed to include (drivers/scsi/ufs-core/*.h).
Update the MAINTAINERS file. Add myself as a UFS reviewer.

+ Universal Flash Storage (UFS) is SCSI transport specification for
+ accessing flash storage on digital cameras, mobile phones and
+ consumer electronic devices.
+ A UFS controller communicates with a UFS device by exchanging
+ UFS Protocol Information Units (UPIUs).
+ UPIUs can not only be used as a transport layer for the SCSI protocol
+ but are also used by the UFS native command set.
+ This transport driver supports exchanging UFS protocol information units
+ with a UFS device. See also the ufshcd driver, which is a SCSI driver

- Universal Flash Storage (UFS) is SCSI transport specification for
- accessing flash storage on digital cameras, mobile phones and
- consumer electronic devices.
- A UFS controller communicates with a UFS device by exchanging
- UFS Protocol Information Units (UPIUs).
- UPIUs can not only be used as a transport layer for the SCSI protocol
- but are also used by the UFS native command set.
- This transport driver supports exchanging UFS protocol information units
- with a UFS device. See also the ufshcd driver, which is a SCSI driver
- that supports UFS devices.

- Select this if you need a bsg device node for your UFS controller.

-config SCSI_UFS_HPB
- bool "Support UFS Host Performance Booster"
- help
- The UFS HPB feature improves random read performance. It caches
- L2P (logical to physical) map of UFS to host DRAM. The driver uses HPB
- read command by piggybacking physical page number for bypassing FTL (flash
- translation layer)'s L2P address translation.
