[Buildroot] [PATCH 1/2] boards/raspberrypi: update instructions for Raspberry Pi 2

[Yann E. MORIN]

The instructions for the Raspberry Pi 2 (aka model B2) are the same as
the ones for the Raspberry Pi, so:
  - state so in the existing readme
  - create a symlink raspberrypi2 -> raspberrypi

Also fix typo in spelling of "Raspberry Pi" (two words, not one).

I don't know if it is patchwork, but this ended up as a symlink to 'raspberrypi?'

Committed to next with those issues fixed, thanks.

Will you also send a patch (for master) doing the same for
raspberrypi_dt_defconfig?

Yes, Patchwork is picky with symlinks. This already hapenned quite a few
times recently. Remember the website move?

Thanks! :-)

I can do so, yes... ;-)

Hi Yann,

downloading the kernel source fails seems to be broken:

[That's a bit annoying: when I replied, the reply went to you only, and

Yes, that's not surprising.

The RPi folks are known to rebase their branch rather than merge
upstream.

Also, they do not tag it.

So, we can only use sha1s, and those are prone to disapear from time to
time (rather frequently) and that's a shame.

I'll post an issue on their tracker to ask for tags.

Regards,
Yann E. MORIN.

If you feel it's important to you (and I'm not speaking only to Bernd),
please feel free to voice your concern over there! ;-)
