Please expand on this comment for me.
He is referign to the numerous kcooments on this list over the past few years of how ARM dos not have a way for u-boot to pass inthe MAC to the kernel (via ATAG or any ohter easy way). THe kernel has to, by itself, figure out the MAC.
Is there another architecture in U-Boot passing the MAC address that I could look at to understand what you mean?
Or are you referring to a kernel, architecture specific, command line feature?
look at PPC. old-style passses the MAC for each interface in the bd_t struct. new-style passes the mac address for each interface in the device tree (as local-mac-address tag)
This is highly useful where there is no _common_ place to store the MAC that the eth driver knows about without a platform specific hack. This way the driver just looks in the dts tree and is happy.
