I had posted 2 fixes for at91 based boards:

[U-Boot] net, macb: fix misaligned cache operation warning
http://patchwork.ozlabs.org/patch/663488/
[U-Boot] net, cmd: fix misaligned cache operation warning
http://patchwork.ozlabs.org/patch/663489/

Is there any issue with them?

Did you tried tbot[1]? With it you can checkout, apply patches (directly from
your patchwork ToDo list if you want), compile, install for example U-Boot
and run tbot testcases on the hardware you have ...

I integrated test/py into tbot and use it for testing some boards
(powerpc mpc52xx, imx6, at91, am335x based boards), for example
current mainline on the at91 based board corvus here:

[2] http://xeidos.ddns.net/tests/test_db_auslesen.php#86
     http://xeidos.ddns.net/tbot/id_86/test-log.html

(I add in this testcase to the U-Boot tree I cloned, my patches from
my Patchwork ToDo list, also some local patches, if you interested in,
search for "2016-09-13 04:57:29,684" in
http://xeidos.ddns.net/tbot/id_86/tbot.txt
so if the result is green, I know all my patches in my ToDo list are clean
and work with current mainline ... :-D
(You get a pull request for them, if buildman finishs ;-)
)

May I make a testcase, which compiles a board with different toolchains ...
But as you see in [2] the current used toolchain is also documented,
also the used defconfig ... may we collect other information too...

Currently I have on some boards problems, when I release the serial
line and start test/py ... I have to look for this problem, but If
you go down in the table, there are test/py runs on other hardware too...

And you can do more with tbot, for example start a testcase, which checks,
if a kconfig move patch does not break boards, see such a result in the
commit comment:
http://patchwork.ozlabs.org/patch/668047/
(I do not post a log, because its over ~50MiB ...)

BTW: all boards I test I have not in my hands...

So "my dream" is, that everybody who have a board and want to support
automated U-Boot testing on it, he can setup a so called virtual lab,
and give us ssh access for testing, and we setup such a testserver.
As an example how this could look like, I did for my use such a setup
on a raspberry pi [3] running buildbot and tbot. I use buildbot only
for the webinterface and starting tbot.

I added to tbot an eventbackend, which fills some information while
testing into a mySQL database, and wrote a simple php script which
shows them in a table [2]. It is not perfect nor a fancy webpage, but
a good starting point.

Also if you want to use jenkins, it should be no big deal to integrate
tbot into jenkins (We only need to write a jenkins eventbackend, which
converts the tbot events into a jenkins format ...)

bye,
Heiko

While writting this EMail, I tested for the shc, smartweb, tqm5200
and corvus board the current release .. works!
I used for the smartweb build another loglevel (console only), see
http://xeidos.ddns.net/tbot/id_89/tbot.txt
Its not so confusing then the info logs with timestamp ... but in an
errorcase every information is helpful ...
