[PATCH v3 00/15] Add support for MediaTek MT7621 SoC

[Weijie Gao]

Hi Marek,

Yes. MT7621 does need such a proprietary binary for DDR initialization
and calibration. That's why I submit only the ram-bootable part here.

I'm considering to create a preloader to load and run DDR init&calib
binary and ram-bootable u-boot image. The ram-bootable u-boot image can be appended to the proloader to form the flash-bootable bootloader.

The source code of preloader will be uploaded to github.

Best Regards,
Weijie
