Thoughts on current OE gta01/gta02 integration, kernel, uboot

[Harald Welte]

Hi!

Today I've finally started to use 2007.2 and I have the following
remarks:

1) the yaffs2 support is not working since there's a missing parameter
   to the mkyaffs2image in bitbake.conf.  I'm not yet sure which one is
   the right one for us, will submit a patch later on.

2) the multi-mach support semems to work fine in general, however:

   a) when starting from MACHINE="fic-gta01" and then changeing to
      gta02, it rebuilds quite a number of 'generic' packages such as
      gtk+.  I don't know why that is the case.

   b) a couple of task-*_fic-gta02.ipk files end up in
      deploy/glibc/ipk/all.   I don't think that's right.

   c) the u-boot recipe seems completely broken, since building
      uboot-openmoko for fic-gta02 ends up building all the gta01
      variants of u-boot, but placed in the fic-gta02 directory, which
      is not good.

   d) alsa-states_0.1.0-r3_fic-gta02.ipk and
      sysvinit-inittab_2.86-r36_fic-gta02.ipk are put in
      deploy/glibc/ipk/armv4t.  Is that correct?

   e) the entire kernel is re-built, which is not neccessarry.  We have
      (and will continue to have) one kernel binary that runs on a
      variety of machines.  Our current kernel should run on qt2410,
      smdk2410, smdk2440, fic-gta01 and fic-gta02.  I don't know what
      bb/OE magic is required to teach the buildsystem about this.

   f) dfu-util is built for fic-gta01 but not for fic-gta02.  It should
      be built for both, but actually not placed into the images
      directory.  It's a native binary, and it's completely independent
      of the target machine arch.

   g) sjf2410 is built for fic-gta02 but not for fic-gta01.  I think we
      don't need it built by default on either of them.

   h) I think we need a meta-task that builds the entire system, i.e.
      "openmoko-image + uboot-openmoko" or 
      "openmoko-devel-image + uboot-openmoko".  I think there should be
      a single command that enables the user to rebuild all software.

   i) the modules-*.tgz file doesn't contain the patchset svn revision
      number

   j) the following packages were built in fic-gta02 for yet unknown
      reason.  I personally don't believe there's something gta02
      specific in them:

      neod-dev_0.1.0+svnr2956-r1_fic-gta02.ipk
      neod-dbg_0.1.0+svnr2956-r1_fic-gta02.ipk

  It would be great if Graeme or somebody else with bitbake+OE background
  could look into resolving those issues.

3) svn revisions for kernel + u-boot are frozen right now.  I don't say
   thre is no reason to do so, but I would want to know why those
   specific revisions have been selected, and what particular
   regressions are worked around by using old versions.

Cheers,
