-+.TH KWBOOT 1 "2012-05-19"
-+
-+.SH NAME
-+kwboot \- Boot Marvell Kirkwood SoCs over a serial link.
-+.SH SYNOPSIS
-+.B kwboot
-+.RB [ "-b \fIimage\fP" ]
-+.RB [ "-p" ]
-+.RB [ "-t" ]
-+.RB [ "-B \fIbaudrate\fP" ]
-+.RB \fITTY\fP
-+.SH "DESCRIPTION"
-+
-+The \fBmkimage\fP program boots boards based on Marvell's Kirkwood
-+platform over their integrated UART. Boot image files will typically
-+contain a second stage boot loader, such as U-Boot. The image file
-+must conform to Marvell's BootROM firmware image format
-+(\fIkwbimage\fP), created using a tool such as \fBmkimage\fP.
-+
-+Following power-up or a system reset, system BootROM code polls the
-+UART for a brief period of time, sensing a handshake message which
-+initiates an image upload. This program sends this boot message until
-+it receives a positive acknowledgement. The image is transfered using
-+Xmodem.
-+
-+Additionally, this program implements a minimal terminal mode, which
-+can be used either standalone, or entered immediately following boot
-+image transfer completion. This is often useful to catch early boot
-+messages, or to manually interrupt a default boot procedure performed
-+by the second-stage loader.
-+
-+.SH "OPTIONS"
-+
-+.TP
-+.BI "\-b \fIimage\fP"
-+Handshake; then upload file \fIimage\fP over \fITTY\fP.
-+
-+Note that for the encapsulated boot code to be executed, \fIimage\fP
-+must be of type "UART boot" (0x69). Boot images of different types,
-+such as backup images of vendor firmware downloaded from flash memory
-+(type 0x8B), will not work (or not as expected). See \fB-p\fP for a
-+workaround.
-+
-+This mode writes handshake status and upload progress indication to
-+stdout.
-+
-+.TP
-+.BI "\-p"
-+In combination with \fB-b\fP, patches the header in \fIimage\fP prior
-+to upload, to "UART boot" type.
-+
-+This option attempts on-the-fly conversion of some none-UART image
-+types, such as images which were originally formatted to be stored in
-+flash memory.
-+
-+Conversion is performed in memory. The contents of \fIimage\fP will
-+not be altered.
-+
-+.TP
-+.BI "\-t"
-+Run a terminal program, connecting standard input and output to
-+.RB \fITTY\fP.
-+
-+If used in combination with \fB-b\fP, terminal mode is entered
-+immediately following a successful image upload.
-+
-+If standard I/O streams connect to a console, this mode will terminate
-+after receiving 'ctrl-\\' followed by 'c' from console input.
-+
-+.TP
-+.BI "\-B \fIbaudrate\fP"
-+Adjust the baud rate on \fITTY\fP. Default rate is 115200.
