it depends on the community. both methods are quite common.

nano `find -name ChangeLog.bfin`
read the ChangeLog and the associated commit. this is exactly the
same way gcc works. you want to know what changed for ChangeLog entry
$foo, you look at the commit surrounding it.

i dont know what "u-boot-v2" is, but if you're referring to mainline
u-boot, then it too is not in a usable state. it isnt just random
commercial customers as we support anyone using a Blackfin (students,
hobbyists, whoever). but only if they're using the same source base
we've tested. once we finish moving things to mainline, that will
become our source base. until then, it is not supportable.

*some* of the sources. icebear requires usage of binary blobs in
there to communicate with their USB JTAG.

there are parallel port jtags available for cheap as well as an
ethernet solution. links can be found in the Blackfin docs wiki.

they are constructive and quite in the open source spirit. if you
dont like dealing with binary blobs, then dont complain to people who
can literally do noting about it, do something yourself about it. put
your money where your mouth is.

as you've been told multiple times, that is where we are heading.
asking the same question multiple times but expecting a different
response is the definition of madness is it not ?
