It looks like the MACB driver is broken in 4.20-rc2. I can see these
two messages:
[ 38.530000] macb: GEM doesn't support hardware ptp.
[ 38.540000] libphy: MACB_mii_bus: probed
but appears to be stuck without ever reaching this message:
[ 38.750000] Microsemi VSC8541 SyncE 10090000.ethernet-ffffffff:00: attached PHY driver [Microsemi VSC8541 SyncE] (mii_bus:phy_addr=10090000.ethernet-ffffffff:00, irq=POLL)
The module never finishes initializing.
Andreas.

That's funny. I _just_ came to the same conclusion.
Here is my bootlog with a backtrace:

..and the code I'm building:
https://github.com/esmil/linux/commits/hfu
I tried reverting Atish' hack, but that's not it.
