Hi,

ECNT (what was once known as trendchip) is now a subsidary of MTK (and 
not a BU if I am understanding it correctly).

the EN7523 is rather similar to the MT7622 for some parts, other parts 
(spi, flash, wdt, gpio, .. drivers all needed to be rewritten and will 
be part of the next series).

the older MIPS silicon shares almost no IP with the current ARM silicon.

not really my call to decide which folder this should live in. it seemed 
natural to just give it its own folder, as ECNT is not a BU of MTK.

we can change that however if required.
