From: Stefan Agner stefan.agner@toradex.com

This commit adds support for the Toradex Computer on Modules Colibri iMX7S/iMX7D. The two modules/SoC's are very similar hence can be easily supported by one board. The board code detects RAM size at runtime which is one of the differences between the two boards. The board also uses the UART's in DTE mode, hence making use of the new DTE support via serial DM.

Signed-off-by: Stefan Agner stefan.agner@toradex.com --- Hi Stefano,

As discussed, only Patch 9/9 from the previous mx7: add Colibri iMX7S/iMX7D support series.

Changes since v2: - Renamed config COLIBRI_IMX7_EXT_PHYCLK and moved to Kconfig
