Subject: tools/kwboot: Add parameters to set delay and timeout via cmdline
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1c0df9ef6ed03baf6fd325dac546290f80c7fd09;p=u-boot.git

tools/kwboot: Add parameters to set delay and timeout via cmdline

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.
