.Sh NAME
|
||||
.Nm imx6_ahci
|
||||
.Nd device driver for the NXP i.MX6 on-chip SATA controller
|
||||
.Sh SYNOPSIS
|
||||
To compile this driver into the kernel,
|
||||
place the following line in your
|
||||
kernel configuration file:
|
||||
.Bd -ragged -offset indent
|
||||
.Cd "device ahci"
|
||||
.Ed
|
||||
.Pp
|
||||
Alternatively, to load the driver as a
|
||||
module at boot time, place the following line in
|
||||
.Xr loader.conf 5 :
|
||||
.Bd -literal -offset indent
|
||||
imx6_ahci_load="YES"
|
||||
.Ed
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
driver provides
|
||||
support for the on-chip SATA controller found on some models of
|
||||
the NXP i.MX6 chip.
|
||||
The driver is a thin glue layer to interpret the platform's FDT
|
||||
data and marshall resources for the standard
|
||||
.Xr ahci 4
|
||||
driver.
|
||||
.Sh SEE ALSO
|
||||
.Xr ahci 4 ,
|
||||
.Xr fdt 4 ,
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
driver first appeared in
|
||||
.Fx 12.0 .
