I took a stab at this, there are many more options to decide on than
mentioned here. I enabled these as modules when possible, and generally
took the default for the rest. Please look over the options below and
let me know if they look reasonable.
Regarding CONFIG_PHY_SUN4I_USB, you've indicated that it should be =y
but it is also available as a module. Is there any reason it cannot be
=m instead?
Note that this is with a 4.12-based kernel.

Title:
enable ARCH_SUNXI (and friends) in arm64 kernel .config
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Artful:
Incomplete
Bug description:
The mainline support for the ARM64 Allwinner SoCs (featured on the Pine64
boards and the Pinebook notebook, for instance, as well as other development
boards like the BananaPi-M64) has come a long way by now, since 4.11 we have
MMC and USB support working.
Now can we just enable the proper .config bits to make the official Ubuntu
kernel support those boards? The latest mainline U-Boot can load an EFI grub
from some UEFI ESP partition, so any standard EFI installer should work.
Apart from some minor hiccup (a missing MBR bootable flag/MBR at all) this
works already with the Debian-testing netinst installer.
The config symbols needed for decent support are (all enabled by the latest
Debian kernel and the official mainline defconfig):
ARCH_SUNXI=y
CONFIG_USB_MUSB_SUNXI=m
CONFIG_MMC_SUNXI=m
CONFIG_RTC_DRV_SUN6I=y
CONFIG_PHY_SUN4I_USB=y
Those enable MMC and USB (the mandatory clocks, pinctrl and UART are enabled
by default) and make those boards quite usable already. The on-SoC Ethernet
driver will probably be merged into 4.13-rc1.
Optionally:
CONFIG_I2C_MV64XXX=m
CONFIG_SPI_SUN6I=m
give us I2C and SPI support as well.
So can we add those symbols to the Ubuntu kernel .config to give users
an out-of-the-box experience?
Cheers,
Andre.
