Yes, "fslc" stands for FSL Community.
There are reasons behind the use of another provider, the main ones are:
- avoid use of version pinning (PREFERRED_VERSION_...);
- make the SoC it targets explicit;
The 3.14.28-1.0.0-GA has only been tested on the *boards* listed in
the release notes. If you take this and use it in another board, this
is not supported by Freescale.
In case you take the 3.14.28-1.0.0-GA kernel and use it in another
SoC, it is at your risk. Freescale does not test the code changes on
the other SoCs so even if some IP components are shared they were not
tested and even checked when the changes in the drivers and
architecture code were done.
In summary the linux-fslc-mx6 is now a 3.14.44 kernel which merges
3.14.28-1.0.0-GA and should ONLY be used for i.MX6 SoCs. There is no
test or check of this tree for another SoCs.
The shared tree for all SoCs are the ones we maintain based on
mainline (4.0, 4.1...) and this can be expected to work on all SoCs.
