[U-Boot] RealTek RTL8211E u-boot driver

[Michal Simek <monstr@monstr.eu>]

Hi guys,

I am having one issue with RealTek RTL8211E u-boot driver.
I found you have added support for this phy in past.

The problem which I have is with rtl8211x_parse_status() where you are
working with page 11.
What was wrong on genphy_parse_link function?

The problem I do see is that SPDDONE bit is 1 but link bit is zero.
That's why phydev->link is setup to 0 which ending up in driver.

Zynq> dhcp
ethernet at e000b000 Waiting for PHY auto negotiation to complete....... done
ethernet at e000b000: No link.

There is sort of 1ms delay between spddone bit and link up.

No problem to add waiting loop in parse status to cover it or just move
to to genphy_parse_link.
Linux realtek driver is using genphy_read_status that's why I think this
is right way to go.

Thanks,
Michal
