[U-Boot] How to get mac address into device tree for powerpc?
I have u-boot retrieving the mac address from the i2c eeprom and using it fine.
But it's not clear to me how I should go about getting it into the device tree so that the kernel can use it.
Is there anyway to do this without doing it manually from the command line?
Thanks,
John

Call fdt_fixup_ethernet() from your board initialization (see common/fdt_support.c). You may want to look at some other utilities in there and at some example calls from board configurations, e.g. board/freescale/mpc8360emds/mpc8360emds.c to pick one pseudo randomly (I don't know if that is the best example, YMMV, etc.).
Thanks,
John
