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 very similar, only with different peripherals. This patchset adds basic "boots to a console" support for the EN751221 family and adds SmartFiber XP8421-B, a low cost commercially available board that is useful for testing and development. Note that Airoha (AN7523, AN7581) is similar to EcoNet in terms of peripherals, and for historical reasons Airoha chips are sometimes referred to with the EN75xx prefix. However this is a different platform because Airoha chips are ARM based.

The series introduces a new platform. The patches are touching different susystems managed by different maintainers. Usually, the changes are per subsystem, except when they are interdependant. Here you can choose to merge all the patches through the mips tree or let the different maintainers to pick the changes related to the subsystems they handle. You should clarify that in the cover letter. If you choose the first alternative, then before merging the changes, all maintainer should have blessed the patches with their acked-by. -- <http://www.linaro.org/> Linaro.org │ Open source software for ARM SoCs Follow Linaro: <http://www.facebook.com/pages/Linaro> Facebook | <http://twitter.com/#!/linaroorg> Twitter | <http://www.linaro.org/linaro-blog/> Blog
