From: Shawn Guo Date: Wed, 20 Mar 2019 07:32:41 +0000 (+0800) Subject: poplar: enable Ethernet driver support X-Git-Tag: v2019.07-rc1~11^2~14 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7c798a11d499dbf5c1c12eedec6bd7299b906b2b;p=oweals%2Fu-boot.git poplar: enable Ethernet driver support The 'phy' reset of gmac device in kernel device tree is not generic enough for u-boot to use, so we need to overwrite the 'resets' property as needed. With this device tree fixup and poplar_defconfig changes, Ethernet starts working on Poplar board.
