Hello,

This is first round (time) to add U-boot support for MediaTek SoCs (MT7623n and MT7629),
and the most of the drivers are based on mainline Linux, like clock, timer, mmc, pinctrl,
watchdog, power domain and DTS.  

The following are the major differences between Linux and U-boot:
- modify the driver interface to adapt the U-boot DM framework.
- remove unneeded DT nodes as they don't have proper drivers in U-boot yet.
- just add the basic functions (step-by-step) so that we can monitor the size.
- reuse ns16550.c but add a highspeed register for MediaTek UARTs.
- add a whole new SNOR driver mtk_qspi.c which is based on SPI master-slave hierarchy.

Our current progress:
The MT7623n (BananaPi R2) which has already supported in mainline Linux.
- We can choice to boot from eMMC or SD card. (ROM -> MediaTek preloder -> U-boot ...)
- MT7623n has an open development board called BananaPi R2 [1].

The MT7629 which has NOT supported in mainline Linux yet, but we will do it soon.
- Boot from SNOR. (ROM -> (boot header parsing sequence) -> SPL -> U-boot ...)

Thanks,
Ryder

I tried the series on my bananapi-r2 and I was able to boot into the kernel:
