I'm wondering what the "correct" way to export a MAC address from u-boot to a Linux kernel. No official driver but the au1000_eth one seems to have support for a "ethaddr=" command line parameter, and I think this does only work with "ethaddr=" being on the kernel commandline, not in the u-boot environment.
How is this intended to work?
As usual, it depends. On PPCs for example, the bd_info structure is passed into the kernel, and drivers can access the MAC address from there. The right way to do it on ARM would probably be to define a corresponding tag.
There are also patches to access the U-Boot environment right in the flash using MTD.
