Hi Alex,
Can you tell me which platforms you verified these patches on? From
what I see, it shouldn't affect regular fastboot operation, but just
in case: do you have some public Git tree with these patches, so that
I can verify them on TI boards? I can also verify UDP functionality as
well, if you want me to. In that case, please provide instructions (or
link to documentation) which I can use for testing.
Thanks.
