EcoNet MIPS SoCs are big endian machines based on 34Kc and 1004Kc processors. They are found in xDSL and xPON modems, and contain PCM (VoIP), Ethernet, USB, GPIO, I2C, SPI (Flash), UART, and PCIe. The EcoNet MIPS SoCs are divided broadly into two families, the EN751221 family based on the 34Kc, and the EN751627 family based on the 1004Kc. Individual SoCs within a family are roughly the same, but with different peripherals. This patchset adds very basic "boots to a console" support for the EN751221 family. EN751627 support and additional drivers will come in a future patchset. Note that while EcoNet is similar to Airoha (AN7513, AN7581) in terms of peripherals, it is different because Airoha is based on ARM. This patchset is against mips-next.
