This adds a general board file based on MT7623 SoCs from MediaTek.
As this u-boot is loaded by MTK proprietary preloader, there is no low level initializtion codes.

Can this use the bloblist feature which should land soon?
For now, see dm/spl-working.

Hi Simon,
I've read the code for spl handoff. It's a good way though but unfortunately it cannot be applied to the MT7623 boards.
The reason is that MT7623 uses a MediaTek proprietary preloader which has the same function as the U-Boot SPL. But the preloader is close-sourced (by company policy) and only available in binary release. This means we can't use a real U-Boot SPL to replace the preloader.
At present this chip has already been used in many products. We can't either release a different preloader which introduces compatibility issues.
So the conclusion is that we cannot use the bloblist feature for this SoC.
Best Regards, Weijie
