Thu Dec 19 12:40:53 CET 2019
modified: arch/mips/dts/Makefile
Add support for creation of vocore2.dtb
move creation of gardena-smart-gateway-mt7688.dtb and
linkit-smart-7688.dtb to more specific setting.
new file: arch/mips/dts/vocore2.dts
modified: arch/mips/mach-mtmips/Kconfig
new file: board/vonger/vocore2/Kconfig
KConfig support for board VoCore2.
new file: board/vonger/vocore2/Makefile
new file: board/vonger/vocore2/board.c
Board initialization (largely copied from existing).
new file: configs/vocore2_defconfig
new file: include/configs/vocore2.h
Board settings (WIP).
