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. Signed-off-by: Tom Rini <trini@konsulko.com>

|
|
* PHYs are the two on-board 1Gb ports. There are no RGMII PHY on board.
|
|
* The 10Gb XGMII PHY is provided via the XAUI riser card. There is only
|
|
* one Fman device on B4860. The SERDES configuration is used to determine
|
|
* where the SGMII and XAUI cards exist, and also which Fman MACs are routed
|
|
* to which PHYs. So for a given Fman MAC, there is one and only PHY it
|
|
* connects to. MACs cannot be routed to PHYs dynamically. This configuration
|
|
* is done at boot time by reading SERDES protocol from RCW.
