Subject: arm: mx6: Make all i.MX6 SoCs user-selectable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have a number of platforms that are a combination of a carrier board
and System-on-Module (SoM) that in turn allows for the board to have
different SoCs on it.  In some cases, this is handled via board-specific
Kconfig options.  In other cases we make use of
CONFIG_SYS_EXTRA_OPTIONS.  This latter case however can lead to invalid
configurations as we will not in turn get options that in Kconfig are
selected by or depend on that setting.

To resolve this, make the SoC option a choice in Kconfig and make boards
depend on what they can support.  This change opens us up for further
clean-ups in the cases where a single CONFIG_TARGET_xxx can support
different SoCs and today they do not, or do not cleanly do so.
