I have seen Anand's your question in [0]: > only issue is I have is the each time their is random MAC address so I > get new IP from dhcp server. > How can I avoid this. I have tried to enable eFuse driver but with no success.
u-boot on the 64-bit SoCs can read the MAC address from the eFuse and pass it (via the .dtb) to the kernel. This requires an ethernet0 alias in the mainline .dts though, see [1] for and example. I'm not sure if this also works with the older u-boot on the 32-bit SoCs. if it doesn't then there's a nvmem-cells binding for all Ethernet controllers: [2] (please note that the function implementing this binding was recently renamed: [3]) as far as I can tell the stmmac driver doesn't support the nvmem-cells based binding yet Anand, if you want to work on this: feel free to do so! I have the SDHC MMC driver and a discussion about the power-domain drivers on my TODO-list, so I'm pretty busy at the moment.
