Yes. It is documented on the commit log as follows:

commit d5e730317a4d1aa94bdfbf25654847fe788d70df

    Drop Freescale official Linux kernel for i.MX23, i.MX28 and i.MX5
SoC families

    The Linux kernel provided by Freescale for i.MX28 and i.MX5 is too
old
    (2.6.35.3) and there are no plans to upgrade it, as the OE-Core is
    going to use GCC 5.2 as default compiler soon and it is not
possible
    to compile this kernel with the new toolchain, thus the removal.

    The metadata related to the i.MX23, i.MX28 and i.MX5 SoC family,
which
    is dependent of this Linux kernel support, has been removed in
this
    commit so if someone ever wants to bring it back it is easy to
find
    out all the necessary changes. The recipes affected are:

     - alsa-state
     - amd-gpu-x11-bin
     - gtk+3
     - imx-lib
     - imx-test
     - imx-vpu
     - libfslcodec
     - linux-imx
     - mesa
     - qt4-embedded-free
     - qt4-x11-free
     - qtbase
     - xf86-video-imxfb

As mentioned on the commit log, it is easy to bring its support back
as far someone gets a working kernel with current toolchain /or/ adds
support for mainline GPU. I think there were some work on this regard
in past but I am not aware of how good is it. If you find someone
please let us know.
