	  EcoNet EN75xx MIPS devices are big endian MIPS machines used

	  in XPON (fiber) and DSL applications. They have SPI, PCI, USB,

	  GPIO, and Ethernet, with optional XPON, DSL, and VoIP DSP cores.

	  Don't confuse these with the Airoha ARM devices sometimes referred

	  to as "EcoNet", this family is for MIPS based devices only.

	  very similar, so is it enough to select the right family, and

		  The EN751221 family includes EN7512, RN7513, EN7521, EN7526.

		  They are based on single core MIPS 34Kc processors. To boot

		  this kernel, you will need a device tree such as

		  MIPS_RAW_APPENDED_DTB=y, and a root filesystem.
