Some of Spansion/Cypress chips have overlaid 4KB sectors at top and/or bottom, depending on the device configuration, while U-Boot supports uniform sector layout only. The spansion_erase_non_uniform() erases overlaid 4KB sectors, non-overlaid portion of normal sector, and remaining normal sectors, by selecting correct erase command and size based on the address to erase and size of overlaid portion in parameters. Since different Spansion flashes can use different opcode for erasing the 4K sectors, the opcode must be passed in as a parameter based on the flash being used.
