From: Subbaraya Sundeep <sbhatta@marvell.com> This patch set emulates Ethernet MAC block present in Microsemi SmartFusion2 SoC. v6: Fixed destination address matching logic Added missing break in emac_write v5: As per Philippe comments: Returned size in receive function Added link property to pass DMA memory Used FIELD() APIs Added mac_addr in emac state Used FIELD_EX32 and FIELD_DP32 APIs Simplified if else logics in emac_write/read v4: Added loop back as per Jason's comment v3: Added SmartFusion2 ethernet test to tests/acceptance v2: No changes. Fixed Signed-off mail id in patch 2/2 Testing: 1. Download u-boot.bin, uImage and msf2-devkit.dtb from https://github.com/Subbaraya-Sundeep/qemu-test-binaries.git 2. Copy uImage and msf2-devkit.dtb to suitable Qemu tftp directory 3.
