Small patch series to add support for VoCore/VoCore2 board.
VoCore is open hardware and runs OpenWrt/LEDE. It has WIFI, USB, UART, 20+ GPIOs but is only one inch square. It will help you to make a smart house, study embedded system or even make the tiniest router in the world.
Details about this SoM can be found at "https://vocore.io/v2.html".
Signed-off-by: Mauro Condarelli mc5686@mclink.it
Changes in v3:
- based on top of Weijie Gao patchset: "[v3,xx/20]Refactor the architecture parts of mt7628"
Changes in v2:
Removed some dead code
Changed Author to my full name (no nick)
Removed unwanted fixup to .dts generation (not my call).
Fixed commit message
Fixed various variables/filenames to include Vendor name
Changed Vendor name (Vonger -> Vocore)
