Currently, kwboot only allows dynamic UART boot mode patching for SoCs
with header version 0 (Orion, Kirkwood). This patch now enables this "-p"
feature also for SoCs with header version 1 (Armada XP / 38x etc). With
this its possible now to use the UART boot mode without on images that
are generated for other boot devices, like SPI. So no need to change
BOOT_FROM to "uart" for UART xmodem booting any more.

To support the Armada 38x, new values for the request-delay and the
response-timeout are needed. As the values already implemented in
this tool (for Kirkwood and Armada XP) don't seem to work here.
To make this more flexible, lets add make those 2 parameters
configurable via the cmdline. Here the new parameters:
-q <req-delay>: use specific request-delay
-s <resp-timeo>: use specific response-timeout
For the Marvell DB-88F6820 these values are known to work:
One board:
-q 2 -s 1
2nd board:
-q 5 -s 5
So this seems to be even board specific. But with this patch now
those values can be specified and tested via the cmdline.

The barebox version of the kwboot tool has evolved a bit. To support
Armada XP and Dove. Additionally a few minor fixes have been applied.
So lets sync with the latest barebox version.
Please note that the main difference between both versions now is, that
the U-Boot version still supports the -p option, to dynamically patch
an image for UART boot mode. I didn't test it now though.

The kwboot program boots boards based on Marvell's Kirkwood platform
via Xmodem over their integrated UART.
