Most of the commits are for defconfig changes, to enable newly added
drivers or features that people have started using. For the changed
lines lines, we have mostly cleanups, the affected platforms are
OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
The largest single change is the introduction of the TI "sysc" bus
driver, with the intention of cleaning up more legacy code.
Two new SoC platforms get added this time:
- Allwinner R40 is a modernized version of the A20 chip, now
with a Quad-Core ARM Cortex-A7. According to the manufacturer,
it is intended for "Smart Hardware"
- Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family
of chips meant for managed gigabit ethernet switches, based
around a Cortex-A9 CPU.
Finally, we gain SMP support for two platforms: Renesas R-Car E2
and Amlogic Meson8/8b, which were previously added but only supported
uniprocessor operation.
