Hello,
This is the new round to add U-Boot support for MediaTek SoCs - MT7623n & MT7629, and the most of the drivers are based on mainline Linux, such as clock, timer, mmc, pinctrl, watchdog, power domain and device tree.
The following are the major differences between mainline Linux and U-Boot: - Modify the drivers 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 UART driver ns16550.c but add a highspeed register for MediaTek chips. - Add a whole new MT7629 SNOR driver which is based on SPI framework.
Our current progress:
The MT7623n (BananaPi R2) which has already been supported in mainline Linux. - Boot from eMMC or SD card. - Boot flow: ROM -> MediaTek's preloder -> U-Boot ... - An open development board called BananaPi R2 [1].
The MT7629 is NOT supported yet in mainline Linux, but I will add it soon. - Boot from SNOR currently. - Boot flow: ROM -> (boot header parsing sequence) -> SPL -> U-Boot ...

Current implementation was validated via the FIT image.
Thanks, Ryder
Changes since v2: - Squash defconfig parts into other patches. - Drop unneeded definitions in include/configs/*. - Add a MT7629 qspi driver in the series.
Changes since v1: - Fix new blank line at EOF and indentation. - Revise commit message. - Add missing sgmiisys device nodes. - Add Tested-by tags from Matthias. - Drop MT7629 qspi driver in the series, and we will implement another one based on the spi-mem framework.
