I'd like to port Clause 45 PHY support and more recent Linux phylib
extensions to Barebox. Ideally it should be possible later to apply
most Linux patches as-is on Barebox. Before I start two questions:
- Any guidelines what it typically takes to port Linux Kernel code
to Barebox? (I suppose at least removing mutexes + spinlocks, changing
all interrupts to polling)
- Especially regarding drivers/net/phy: any plans I should be aware of?

Well yes, and that's about it. Sometimes you have to simplify the code,
sometimes you have to update some header files we have from Linux.

Much of the code is from Linux, but there's also much barebox original
code. I don't think the goal should be that it looks identically in the
end.
