[U-Boot-Users] smc911x: cannot pass the MAC address from U-Boot to the Linux driver via chip registers

Hi,
in the smc911x U-Boot driver the call of eth_halt() causes a reset of
the ethernet controller. This also resets the MAC address in the
according chip registers. This makes it impossible to pass the MAC
address to an ARM kernel because the smc911x linux driver reads the MAC
address from the MAC registers and complains if the found values are
invalid.
Any ideas to solve this problem, e.g.
- rewriting the MAC address after reset?
- not to reset the chip?
- another passing mechanism to the kernel?
- or ...
Best Regards,
Jens
