[meta-raspberrypi][PATCH 1/1] pi-blaster: Added recipe

[Alex J Lennon]

This project enables PWM on the GPIO pins you request of a Raspberry Pi. The technique used is extremely efficient: does not use the CPU and gives very stable pulses.

Fair comment. I am somewhat in the dark as to the usefulness of the 0/1
covernote myself. I usually provide it as that's what seems to be
required by use of the recommended create-pull-request but sometimes I
feel it's overkill (?)

Cheers,

Alex

Agreed. I don't use covernote generally. Only for very big pull requests
that really need additional info for the whole "package". But for small
pullreqs, I only send the actual patches. For me, seems enough.

You missed the actual patch so I will give my feedback listed below:
1. Refactor commit log.
2. One space left after "oe_runmake".
3. Why exactly do you need oe_runmake after all?
4. I would replace the do install/configure appends with a patch on
Makefile (would be useful for the project's maintainer too).
5. Please add comments to patches too. Here is an example:
http://git.yoctoproject.org/cgit/cgit.cgi/meta-raspberrypi/tree/recipes-bsp/rpi-mkimage/rpi-mkimage/open-files-relative-to-script.patch

Thanks,

Thanks for the comprehensive response Andrei, and also for the link to
the OpenEmbedded Commit Patch Message Guidelines - very useful.

I've reworked the pi-blaster recipe, hopefully in line with your
comments, and pushed a second patch-set up to the review server.

Regards,

Alex
