From c13f60d92a1c31c131a53ff8e994e4c8eebb8311 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 25 Jan 2015 12:10:48 +0100 Subject: sunxi: Add a GMAC Transmit Clock Delay Chain Kconfig option And use this to set the GMAC Transmit Clock Delay Chain value on Banana boards, rather then keying of CONFIG_TARGET_FOO.
