This selects the support for UFS devices in Linux, say Y and make
|
|
sure that you know the name of your UFS host adapter (the card
|
|
inside your computer that "speaks" the UFS protocol, also
|
|
called UFS Host Controller), because you will be asked for it.
|
|
The module will be called ufshcd.
|
|
|
|
To compile this driver as a module, choose M here and read
|
|
<file:Documentation/scsi/ufs.txt>.
|
|
However, do not compile this as a module if your root file system
|
|
(the one containing the directory /) is located on a UFS device.
