AST2700 FMC/SPI controllers are not compatible with AST2600 due to the following hardware differences: - Address decoding unit uses 64KB granularity (AST2600 uses 1MB). - Segment register semantics are changed. AST2600: start <= range <= end AST2700: start <= range < end - Hardware limitations in AST2600 address decoding registers have been resolved in AST2700, so extra callback function used for bug fixup is no longer required. These differences require distinct compatible strings for AST2700.
