I think this is an excellent point.
If we can make this work well, including
FSF assignments, then eCos should see a real boost in hardware
support... There are *LOTS* of eCos HAL's there that never make it
into the official eCos repository, simply because there is no manpower.
Though I don't believe that eCos itself should use submodules, much,
rather that the application engineer would use one submodule for the offical
core eCos repository and another submodule for the OMAP parts.
There are, as you point out, a very small crowd that will be interested
in the OMAP HAL's and only for as long as it is in the job description.
(You can list several eCos repositories in ECOS_REPOSITORY environment
variable, a much undervalued, undermarketed feature...)
