Hello,

These 4 patches are meant to enable ethernet and SD/MMC for the SOCFPGA platform.

patch (1/4): Adds select ARM_TWD for the platform
patch (2/4): Add platform specific initialization for the ethernet controller.
patch (3/4): Commit 25c83b5c2 added "snps,phy-addr" for getting the PHY addr.
Set the ethernet clocks to be emac_0_clk and emac_1_clk so it
be gated.
patch (4/4): Update defconfig to support SD/MMC, ethernet, EXT3 and NFS.

Thanks,

Hi Dinh,

What tree is this based against, or what patches are a pre-requisite to this series? I applied the patches to linux-arm/master but the compile failed.
