[Buildroot] [PATCH] board: solidrun: add Clearfog GT-8K

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

Hello Baruch,

This mostly looks good, I just have one question (below), and some
minor nits that I would have ignored if I didn't had the question.

The commit title should preferably be:

	configs/solidrun_clearfog_gt_8k: new defconfig

I think we more commonly use "-" as a separate in board directory names
instead of "_", so there's not a strong convention on this.

So the switch driver is enabled to be built in the kernel image
itself...

... but you tell people to load it as a kernel module ?

This seems weird. Am I missing something ?

So there is no ATF configuration specifically for the GT-8K platform ?

Thanks!
