I don't mean it already covers DW boards (I haven't got one) though no significant modifications should be necessary. IIRC, DW boards use CFI-compliant flash so common CFI driver can be used instead of the board-specific one.

PlanetCore saves its environment in the I2C EEPROM so it's not affected by the flash configuration. Also, the EEPROM contains exact board hardware configuration (board version, RAM size, flash size, etc.) probably burned there during manufacturing process so PlanetCore can initialise the board accordingly. It's possible to use this information in the U-Boot but some hard-coded values still remain. CFG_MONITOR_LEN and CFG_ENV_SECT_SIZE are a problem, especially now when we've got universal CFI driver. In theory, CFI driver detects the flash configuration automatically so the same U-Boot image can work on different boards. In real world, CFG_MONITOR_LEN and CFG_ENV_SECT_SIZE must be specified in compile time so different flashes can result in different images. I'd like to remove these compile time values. Any ideas if and how it's possible?
