+ * modified for TOP5200 by Reinhard Meyer, www.emk-elektronik.de
+ * 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 located at 0x80000000
+ * Internal regs are at 0xfff00000
+ * Reset jumps to 0x00000100
