Brooks Davis 087d31736a Add isf(4), a driver for the Intel StrataFlash family of NOR flash parts.
The driver attempts to support all documented parts, but has only been
tested with the 512Mbit part on the Terasic DE4 FPGA board.  It should be
trivial to adapt the driver's attach routine to other embedded boards
using with any parts in the family.

Also import isfctl(8) which can be used to erase sections of the flash.

.Sh NAME
.Nm isfctl
.Nd Intel StrataFlash device control program
.Sh SYNOPSIS
.Nm
.Ar device
.Ic erase
.Ar offset
.Ar size
.Sh DESCRIPTION
The
.Nm
utility provides a way for administrators to control aspects of
.Xr isf 4
devices that can not be managed though the
.Xr disk 9
interface.
.Pp
The
.Nm
utility takes a device name as its first argument followed by a command.
Currently supported commands are:
.Bl -tag -width erase
.It Ic erase
Erase blocks beginning at
.Ar offset
covering a total of
.Ar size
bytes.
The
.Ar offset
argument must be a multiple of 128K.
The
.Ar size
argument must either be a multiple of 128K or a number less than 32K in
which case it is treated as a number of 128K blocks to erase.
.El
.Sh EXAMPLES
.Dl isfctl isf0 erase 0 0x20000
.Pp
Erase the first block of the isf0 device.
.Sh SEE ALSO
.Xr isf 4
.Sh HISTORY
The
.Nm
utility first appeared in
.Fx 10.0 .
