Or PHY Lib for U-Boot.
This sequence of patches adds infrastructure for universally-available PHY drivers (and MDIO drivers). It piggy-backs on the existing miiphy code, for backwards compatibility, but it also creates a new set of APIs. This was necessary partly to provide cleaner interfaces for more robust driver support, and partly because one goal was to support 10G (802.3 Clause 45) MDIO buses, which has an extra argument for addressing PHY registers.
Special thanks goes to Mingkai Hu, who did a substantial amount of work up front to convert the tsec PHY code into something more usable, which I have mostly copied for the purposes of PHY Lib.
In this version, I cleaned up all of the comments, separated out some of the changes which were just formatting, and brought back the mdio command.
The new mdio command loses the "busname:addr" addressing mechanism, as "busname addr" felt more natural to me (though I expect most people will go with "ethname", as the ethernet names are much more visible. In addition, the <devad> argument is now optional by way of being combined with the reg argument: [<devad>.]<regnum>. This makes sense, as this is also how the registers are described in the specs and in the data sheets. ie:
Register 7.1 - AN Status
I've put the relevant changelogs in the patches. Enjoy!
