They support a maximum capacity of 16GB FLASH per chip, with a maximum page size of 8KB. The chip supports up to 4 chip selects and 4 RDY signals. The key difference between the Loongson-2K NAND controllers is that the Loongson-2K1000 explicitly configures the DMA controller routing, while the Loongson-2K0500 defaults to using APBDMA0. Summary of the patchset: Ptach 1-2: Rename all prefixes from ls1x to loongson Patch 3: Add 6-byte NAND ID reading Patch 4: Add chip select support Patch 5-6: Add Loongson-2K0500 NAND controller support Patch 7-8: Add Loongson-2K1000 NAND controller support Thanks.
