NOTE: Some of the 4.13.x VMBus patches did not apply cleanly and they
were dropped for now. This may break LCOW and other Windows support.

- Enable ARCH_BCM2835
- Enable USB_NET_SMSC95XX.
- Compile in MII and USB_USBNET. These are needed
by the onboard network driver
- Enable the DWC2 USB controller.
- Enabled MMC, MMC_SDHCI, MMC_BCM2835 for SD card access
- Enable various BCM2835 platform devices: HW_RANDOM_BCM2835,
I2C_BCM2835, PINCTRL_BCM2835, DMA_BCM2835,BCM2835_MBOX,
WM_BCM2835, ...
- Enable SERIAL_8250 and friends.
- Enable FB_SIMPLE to get console output
The above configuration gives a minimal working system
with serial console access (via the GPIO pins), networking
and SD storage. The smsc95xx network driver does not
seem to get autoloaded. This is likely a mdev issue.
We specifically do not configure any WLAN,
sound or graphics drivers as they would pull in
too many other cruft into the kernel. To enable
these we consider adding a -rpi3 config similar
to the -dbg config to provide additional kernel
config options.

This is a useful read only filesystem for images that is efficient and
small as it supports compression.
For many use cases, when you are writing to media, it makes more sense than
using an initramfs as it does not require RAM, and it is more suitable for
disk media than ISO.

This new feature was disabled by default, enable it as it seems
sensible to have. From the documentation:
Detect overflows of buffers in common string and memory functions
where the compiler can determine and validate the buffer sizes.

The patches from 4.12 applied cleanly, except for 81304747d9
("Drivers: hv: vmbus: Fix rescind handling"), which was already
in upstream so has been dropped from the patch series.
The kernel config is from 4.12 run through defconfig/oldconfig to
pick up any new defaults.
