Tutorial: Install OpenBSD on ROCK64 media board

[krjdev]

I have updated the tutorial for OpenBSD 6.7.

https://github.com/krjdev/rock64_openbsd

Biggest change:
- add official solution to install OpenBSD (Using idbloader.img and u-boot.itb).

Please can somebody proof-read my tutorial?

EDIT:
I have also build idbloader.img and u-boot.itb.

Used U-Boot version:

Code:

$ git-describe
v2020.07-rc2-194-gb0b13f4114
$

Used version ATF version:

Code:

$ git-describe
v2.3-55-gf1a1653ce
$
