This series adds U-Boot support for the EcoNet/Airoha EN75xx MIPS SoC family: the big-endian MIPS34Kc EN7512/EN7521 and the little-endian MIPS1004Kc EN7528, used in many GPON/XPON ONT home gateways. It extends the existing Airoha SNFI SPI-NAND and GDM Ethernet drivers.
It brings up the SoC (TPL/SPL, cache/CM init), and adds the UART, the EN75 BMT SPI-NAND bad-block mapping, weak bootm decompression hooks for the coherent CM, and Ethernet. Reference boards for the EN7512 and EN7528 are included, plus the EN7528 R3-hook boot variant. The DDR calibration stage is a vendor artifact and is not shipped in-tree. The reference board packages it as a binman "blob-ext"; build those configs with BINMAN_ALLOW_MISSING=1 and supply the blob to run (see arch/mips/mach-en75xx/README.ddr-blob). A native DDR-init implementation is a known TODO. Tested on a Nokia G-2425G-A (EN7528, MT29F2G01 SPI-NAND): boots to the prompt with correct 256 MiB DRAM, working Ethernet/TFTP and SPI-NAND.
