5 * modified for TOP5200-series by Reinhard Meyer, www.emk-elektronik.de
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
