that's this board:

there's an alleged page for downloading an appropriate layer here:
http://www.rocketboards.org/foswiki/Documentation/GitGettingSTarted#Yocto_Project
with the instructions:
$ git clone http://git.rocketboards.org/poky-socfpga.git
$ cd poky-socfpga/
$ git checkout -b <test_branch_name> origin/danny-altera
$ source ./altera-init build
$ bitbake virtual/kernel virtual/bootloader altera-image
but those instructions clearly won't work as that checkout doesn't
include the script "altera-init" and doesn't define an "altera-image".
there's a much larger downloadable image called
"linux-socfpga-13.02-RC10-src.bsx", but it's well over 800M and is
defined to contain *everything* you need to build (that's all the
source and everything), but i don't want to go down that road as i'm
pretty sure i have most of the source.
so is there, in fact, a valid meta-altera(?) layer of some kind that
defines the machine, image(s) and recipes for the arrow sockit board,
without cluttering the download with 800M+ of extraneous junk? thanks.

Hi Robert,
I recently went on a training day with EVB (at Altera offices) and
they said the only supported method was through the Altera downloads
and rocketboards community site, for there dev board. They were not
aware of any 'meta-altera' layer (which is madness).
I am attending an Arrow training day in the coming weeks (where they
give this board out for free) so it will be interesting to see if
you get anywhere with this as I will be incorporating my own distro,
and as such need a fully layered approach.
If you still need me to ask any questions in a couple of weeks I
will do so for you.
over the last couple of hours, i've got a lot of it figured out.
i've started (unsurprisingly :-) to document everything here:
http://www.crashcourse.ca/wiki/index.php/Arrow_SoCKit
the web page that suggests there is a separate layer:
http://www.rocketboards.org/foswiki/Documentation/GitGettingSTarted#Yocto_Project
seems pretty clearly incorrect, but if you download the monstrous .bsx
file and install it, then run the install_altera_socfpga_src.sh script
that you get inside that, that produces another directory with
contents:
-rwxrwxr-x 1 rpjday rpjday 1547 Mar 27 17:01 altera-init
drwxrwxr-x 6 rpjday rpjday 4096 Oct 26 2012 bitbake
drwxrwxr-x 11 rpjday rpjday 4096 Mar 27 17:01 documentation
-rw-rw-r-- 1 rpjday rpjday 545 Oct 26 2012 LICENSE
drwxrwxr-x 21 rpjday rpjday 4096 Oct 31 2012 meta
drwxrwxr-x 9 rpjday rpjday 4096 Apr 5 15:20 meta-altera

drwxrwxr-x 6 rpjday rpjday 4096 Oct 31 2012 meta-yocto
drwxrwxr-x 9 rpjday rpjday 4096 Mar 27 17:01 meta-yocto-bsp

drwxrwxr-x 8 rpjday rpjday 4096 Mar 27 17:01 scripts
so that's looking a lot more promising. i'm guessing all the content
is there, it's just a bit disorganized. as you can see, there *is* a
meta-altera layer, but it's accompanied by a bunch of other layers
which i suspect could be pruned, so my goal today is to strip out
everything but the minimal meta-altera content and combine it with all
the layers i already have.
stay tuned ...

The interesting ones in there are meta-altera and meta-linaro; it would
also be interesting to see if anything else is modified or if it is
vanilla Yocto. I have a sinking feeling it may not be... mainly due to
the tightly coupled DT and socfpga implementation with the Altera tools.
Could you post the altera-init script; I would imagine that hides the
demons ;)
