.sp
.B " flashrom \-p prog \-l <layout> \-i foo:foo.bin -i bar:bar.bin -w rom.bin
.TP
.B "\-\-wp\-status"
Prints the flash's current status register protection mode and write protection
range.
.TP
.B "\-\-wp\-list"
Prints a list of all protection ranges that the flash supports.
.TP
.B "\-\-wp\-enable"
Enables hardware status register protection (SRP) if the flash supports it.
Once SRP is enabled, operations that change the flash's status registers
(including \fB\-\-wp\-disable\fR and \fB\-\-wp\-range\fR) can only be performed
if the flash's #WP pin is at an inactive logic level.
.TP
.B "\-\-wp\-disable"
Disables status register protection if the flash allows it.
.TP
.B "\-\-wp\-range <start>,<length>"
Configures the flash to protect a range of addresses from <start> to (<start> +
<length> - 1), bounds inclusive. The range must be supported by the flash, see
\fB\-\-wp\-list\fR.
.TP
.B "\-\-wp\-region <region>"
Same as \fB\-\-wp\-range\fR but protects the range occupied by an image region.
This option requires a image layout to be specified, see \fB\-\-layout\fR. The
region must be supported by the flash, see
\fB\-\-wp\-list\fR.
.TP
.B "\-\-flash\-name"
Prints out the detected flash chips name.
Prints out the detected flash chip's name.
.TP
.B "\-\-flash\-size"
Prints out the detected flash chips size.
Prints out the detected flash chip's size.
.TP
.B "\-\-flash\-contents <ref\-file>"
The file contents of
