It was brought to our attention that U-Boot contains code derived from the
IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards.  As a result, the original license of this code has
been carried in the various files for a number of years in the U-Boot project.

IBM is dual-licensing the IBM code contributions already present in U-Boot
under either the terms of the GNU General Public License version 2, or the
original code license already present.

While adding the 460EX/GT support I reworked the 4xx miiphy code. It
badly neede some cleanup.

Every now and then a Sequoia board (or equivalent hardware) had
problems connecting to a Gigabit capable network interface.

There were differences in the PHY setup between Linux and U-Boot.

This patch fixes the problem. Apparently "remote fault" is being set,
which signals to some devices (on the other end of the cable) that a
fault has occurred, while other devices ignore it. I believe the RF bit
was causing the issue, but I removed T4 also, to match up with Linux.

This patch adds a new switch: "CONFIG_PHY_DYNAMIC_ANEG".  When this symbol
is defined, the PHY will advertise it's capabilities for autonegotiation
based on the capabilities shown in the PHY's status registers, including
1000BASE-X.  When "CONFIG_PHY_DYNAMIC_ANEG" is not defined, the PHY will
advertise hard-coded capabilities, as before.
