7a4b6964b5 mips: mtmips: add SPL support
This patch adds SPL support for mtmips platform. The lowlevel architecture
is split into SPL and the rest parts are built into a memory loadable
u-boot image. Optional SPL_DM and OF_CONTROL are also supported.

The increment of size is very small (< 10 KiB) if SPL_DM and OF_CONTROL are
not enabled and the memory bootable u-boot (u-boot.img) is generated
automatically so there is not need to add a separate config for it.

A lzma compressed payload (u-boot-lzma.img) is also generated and it will
be combined with u-boot-spl.bin to form the unified ROM bootable binary
u-boot-mtmips.bin.

A spl loader is added to support uncompress the payload.

5fcea8d3f9 dts: mtmips: enable high-speed UART support for mt7628
All three UARTs of mt7628 are actually MediaTek's high-speed UARTs which
support baudrate up to 921600.
The high-speed UART is compatible with ns16550 when baudrate <= 115200.

Add compatible string to dtsi file so u-boot can use it when serial_mtk
driver is built in.

d1d8814458 dts: mtmips: move uart property clock-frequency into mt7628an.dtsi
The UART of MT7628 has fixed 40MHz input clock so there is no need to put
clock-frequency in every dts files. Just put it into the common dtsi file.

4c835a607b mips: Add basic MediaTek MT7620/88 support
This patch adds basic support for the MediaTek MT7620/88 SoCs. Parts of
the code is copied from the MediaTek GitHub repository:

https://github.com/MediaTek-Labs/linkit-smart-uboot.git

The mt7628a.dtsi file is imported from Linux v4.17.

Support for the LinkIt Smart 7688 module and the Gardena Smart Gateway
both based on the MT7688 will be added in further patches.
