This patch adds support for the "OHB System AG" baseboard with is equipped with the TQMa6S SoM.

Signed-off-by: Stefan Roese sr@denx.de Cc: Markus Niebel Markus.Niebel@tq-group.com Cc: Stefano Babic sbabic@denx.de --- v2: - board_eth_init() simplified as suggested by Markus - PHY reset GPIO only defined once as suggested by Markus - All GPIOs are now requested before usage as suggested by Markus - Used new tqma6 Kconfig IF as suggested by Markus
