Tom Rini 83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style 
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

/*
* Some boards do not have a PHY for each ethernet port. These ports are known
* as Fixed PHY (or PHY-less) ports. For such ports, set the appropriate
* CONFIG_SYS_UECx_PHY_ADDR equal to CONFIG_FIXED_PHY_ADDR (an unused address)
* When the drver tries to identify the PHYs, CONFIG_FIXED_PHY will be returned
* and the driver will search CONFIG_SYS_FIXED_PHY_PORTS to find what network
* speed and duplex should be for the port.
*
* Example board header configuration file:
* #define CONFIG_FIXED_PHY 0xFFFFFFFF
* #define CONFIG_SYS_FIXED_PHY_ADDR 0x1E (pick an unused phy address)
*
* #define CONFIG_SYS_UEC1_PHY_ADDR CONFIG_SYS_FIXED_PHY_ADDR
* #define CONFIG_SYS_UEC2_PHY_ADDR 0x02
* #define CONFIG_SYS_UEC3_PHY_ADDR CONFIG_SYS_FIXED_PHY_ADDR
* #define CONFIG_SYS_UEC4_PHY_ADDR 0x04
*
* #define CONFIG_SYS_FIXED_PHY_PORT(name,speed,duplex) \
* {name, speed, duplex},
*
* #define CONFIG_SYS_FIXED_PHY_PORTS \
