I've tried to clarify this a bit.  The update is below.

- Paul

For boards that I don't have access to, that I don't have 
documentation for, such as the AM43xx and DRA7xx), for me to merge or ack 
SoC infrastructure or PM-related patches, I want to have:

1. a Reviewed-by: from people who:

a. I think know something about SoC integration or PM in general, and 
about OMAP-style integration specifically; and

b. who have a track record of doing strong and detailed reviews of that 
code, or who have contributed significantly to that code in the past.

My initial list of those reviewers is listed above, and I am happy to 
consider extending it or modifying that list.

2. confidence that the patch or series has been tested against a mainline 
commit and isn't obviously breaking other things, like PM, and confidence 
that it's not adding new runtime warnings.

I've listed an initial set of people above who I feel have proven track 
records in testing who I'm happy to accept Tested-by:s without further 
explanation.  I'm sure I've missed some folks and if anyone who should be 
on that list is offended that I didn't mention them, please accept my 
apologies.  For other folks, like yourself, who aren't on that list (yet), 
please just specifically state:

a. what mainline commit they've tested the patch against,

b. what other prerequisite patches were needed for the patch to apply,

c. and a cut-and-paste of the serial console boot log from the boot 
portion of the test.

in such a way that myself or someone else can easily doublecheck it. 

And frankly, I'll probably be happy to merge it.

After someone has done these three things a few times, and I gain 
confidence that they're doing the right thing, I'm happy to add them to 
my list.

The testing doesn't have to be expressed via a Tested-by: tag in cases 
where you're testing as part of a Signed-off-by:.  Just be sure to state 
those three things above as part of the patch or series message.  The boot 
log can either be placed on a different page and linked to, or sent in 
another public E-mail.

If you can get two or three people to do the above, that's great - the 
more, the better.

...

These two steps do not apply to boards that I have in my testbed or which 
I have documentation for (although they would definitely be very welcome 
in those cases too).
