[package] uboot-kirkwood: update to 2012.04.01

iConnect board tested by:

Tim Fletcher <tim@night-shade.org.uk>
Wojciech Dubowik <wojciech.dubowik@neratec.com>

DockStar board tested by:

Martin Mueller <mm@sig21.net>

RaidSonic ICY BOX NAS6210 board tested by:

Luka Perkov <uboot@lukaperkov.net>

SheevaPlug was not tested but support for SheevaPlug is taken from upstream
uboot and it is not reported to be broken there.

++.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.
