Commit Message

Weijie Gao Oct. 16, 2020, 7:35 a.m. UTC
The mt7620_rfb board supports integrated 10/100M PHYs plus two external
giga PHYs. It also has 8MB SPI-NOR, mini PCI-e x1 slot, SDHC and USB.

The mt7620_mt7530_rfb boards supports an external MT7530 giga switch and a
16MB SPI-NOR flash.

This config is used for the mt7620 uart driver (non-DM mode) in SPL.
This option is similar to the CONFIG_SYS_NS16550_CLK. But since mt7620
uart driver is not compatible with the ns16550a driver, I have to define
new configs for it.

Please refer to [PATCH 08/18] serial: add uart driver for MediaTek
MT7620 SoC
