[PATCH 0/6] misc ethernet fixes and new driver

Hi,

I ported the designware ethernet driver from u-boot, it
only required minor changes and worked right away.
Since my hw has 1G ethernet I added support for this,
although speed is not so important in a boot loader it seemed
easier than to reconfigure the PHY for 100Mbit.

Patches 4 and 5 may be a bit controversial.  The motivation
for patch 4 is that took me some head scratching to get
debug read/write on PHY regs correct since md and mw worked
against my intuition on /dev/phy0.
The string in eth_set_ethaddr() confused me to think a string
would be passed to ->set_ethaddr().  Changing "unsigned char *adr"
to "u8 adr[6]" does not change the generated code but is IMHO
harder to misunderstand.
