Use gpio.h definition of GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW. Remove unused backup partition to increase available JFFS space. As long as U-Boot env variable "bootcount" is < 3 (reset to 0 after boot by init script) SamKnow's U-Boot will not attempt to boot from the backup flash address (0xe30000).
