[U-Boot] [PATCH v4 0/8] add support for atheros ath79 based SOCs

[Daniel Schwierzeck]

Hi Wills,

please take care of following suggestions in your next patch series:

Always respond to comments by reviewers, either by acknowledging a
suggested change or by rejecting it with an explanation why the
suggested change is not appropriate. Also tell them in advance which
changes you are going to make. Maintain a change history per patch.

Do not send too much patch series consecutively. Give reviewers some
time (several days) to review or respond to a new patch series. Keep in
mind that there currently are holidays in Europe and North-America and a
lot of maintainers/custodians are not available because of it.

Try to use patman for maintaining and submitting your patch series.
Patman makes it easier for you to maintain change histories, commit
notes, cover letters and so on.
