+ * 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
