Subject: [U-Boot] [PATCH u-boot v3 1/5] ARM: arch-meson: add ethernet common init function
Date: Mon, 27 Nov 2017 10:16:16 +0100	[thread overview]
Message-ID: <1511774180-22672-2-git-send-email-narmstrong@baylibre.com> (raw)
In-Reply-To: <1511774180-22672-1-git-send-email-narmstrong@baylibre.com>

Introduce a generic common Ethernet Hardware init function
common to all Amlogic GX SoCs with support for the
Internal PHY enable for GXL SoCs.
