- * TOP5200 differences from IceCube:
- * 1 FLASH Bank for one Chip only, up to 64 MB in 16 MB Banks
- * bank switch controlled by TIMER_6(LSB) and TIMER_7(MSB) Pins
- * 1 SDRAM/DDRAM Bank up to 256 MB
- * local VPD I2C Bus is software driven and uses
- * GPIO_WKUP_6 for SDA, GPIO_WKUP_7 for SCL
- * FLASH is re-located at 0xff000000
- * Internal regs are at 0xf0000000
- * Reset jumps to 0x00000100
