   6  *
   7  * TOP5200 differences from IceCube:
   8  * 1 FLASH Bank for one Chip only, up to 64 MB in 16 MB Banks
   9  *   bank switch controlled by TIMER_6(LSB) and TIMER_7(MSB) Pins
  10  * 1 SDRAM/DDRAM Bank up to 256 MB
  11  * local VPD I2C Bus is software driven and uses
  12  *   GPIO_WKUP_6 for SDA, GPIO_WKUP_7 for SCL
  13  * FLASH is re-located at 0xff000000
  14  * Internal regs are at 0xf0000000
  15  * Reset jumps to 0x00000100
