K210 device tree

[Heinrich Schuchardt]

Hello Sean,

up to now separate device trees for the Kendryte K210 have been
developed for OpenSBI, U-Boot, Linux.

U-Boot can be booted with a device-tree provided by OpenSBI using
CONFIG_OF_PRIOR_STAGE=y in U-Boot.

Linux can also receive a device-tree from firmware.

So wouldn't it make sense to move all the K210 device-tree development
into OpenSBI?

Best regards

Heinrich
