Currently, using kernel config fragments is not working. If you try
adding one as documented in the Yocto Mega Manual [1], it will be
ignored.
There are two reasons for this:
- The config fragment logic is in kernel-yocto.bbclass, so we need to inherit
that (this is similar to what linux-raspberrypi does in meta-raspberrypi).
- We remove ${B}/.config, which undoes any config created by
kernel-yocto.
Fix this by inheriting kernel-yocto and not removing ${B}/.config. With
this patch, fragments are working. Note that we also need to add a few
variables (like KERNEL_KBUILD) to make kernel-yocto happy.

Orange Pi Zero Plus2 board is based on AllWinner H5 SoC.
For more details on its hardware see linux-sunxi wiki:
http://linux-sunxi.org/Xunlong_Orange_Pi_Zero_Plus_2
This patch enables basic support for orange-pi-zero-plus2 board:
- mainline kernel 4.14.2
- mainline u-boot 2017.11
- dts kernel patch that fixes boot from SD card
- dts kernel patch enabling AP6212 WiFi/BT chip

Modify sdcard_image-sunxi bbclass to support both sun50i and older
SoC families. Major changes are as follows:
- update comments: disk layout info
- increase boot partition size: aarch64 unified kernels can be large
- kernel image in boot partition: replace explicit name by KERNEL_IMAGETYPE
- SPL image: replace explicit name by SPL_BINARY
- implement flexible DTB file location in boot partition
-- e.g. by defaut sun50i u-boot looks for dtb in allwinner subdirectory
-- follow kernel dtb naming conventions, e.g. allwinner/<board>.dtb
- copy aarch64 u-boot image to image
-- sunxi arm boards use unified u-boot/spl image
-- sunxi aarch64 boards use two different images

There is no common kernel defconfig for both arm and aarch64.
Create separate kernel defconfigs in arm and aarch64 subdirectories.
Proper defconfig will be selected in build time
according to target architecture.

Add support of sun50i SoC family to u-boot recipe:
- move SPL_BINARY to sunxi.inc and sunxi64.inc
-- different SoC families have different SPL_BINARY names
- create separate boot.cmd files for arm and aarch64
-- different kernel image types require different boot commands
- add atf-sunxi dependency
-- u-boot for aarch64 needs ATF BL31 binary
- add do_compile_sun50i[depends]
-- make sure that BL31 binary is already deployed before u-boot build

Add ARM Trusted Firmware package for Allwinner arm64 chips.
There are different approaches to build bootloaders for aarch64
platforms. Allwinner approach is to build ATF first, and then
to build U-Boot using BL31 binary from ATF build.

Follow the same approach as in 32-bit sunxi SoC families:
- create sunxi64.inc: umbrella description for aarch64 sunxi
-- specify proper u-boot/spl image types
-- specify proper kernel image type
-- specify u-boot/kernel preferred providers
- create basic description of sun50i SoC family
-- sun50i SoC family is based on armv8

- remove older stable release recipes
- bump stable linux recipe to 4.14.2
- bump git linux recipe to 4.15-rc1
- rename linux to linux-mainline
Renaming kernel recipe from 'linux' to 'linux-mainline' is needed to
get ready for adding aarch64 support. The reason is in the value of
OVERRIDES environment variable. BitBake uses OVERRIDES to control what
variables are overridden after BitBake parses recipes and configuration
files. So packages names are not allowed to take values listed in
OVERRIDES. One of the OVERRIDES values is TARGET_OS:
TARGET_OS = linux${LIBCEXTENSION}${ABIEXTENSION}
For arm architecture TARGET_OS = "linux-gnueabi". However for aarch64
architecture TARGET_OS = "linux". As a result, in the case of aarch64
kernel package can not be named 'linux'. This patch renames kernel
package name to 'linux-mainline' in order to be able to maintain the
same kernel recipes for both arm and aarch64 boards.

Binman host tool in u-boot depends on libfdt library and pylibfdt module.
All the needed libraries and python modules are a part of u-boot.
This patch adds libfdt and pylibfdt to u-boot build:
- add required dependencies swig-native and python3-native
- fix python setup-tools issue: pass proper shared lib linker

As suggested by Andrei Gherzan (see #178):
"The current implementation inherits sdcard_image-sunxi.bbclass
unconditionally which in turn, sets two depends on do_rootfs
unconditionally again.
This means that if I want to build an initramfs image in the
kernel image I will get a dependency loop."
