  This demo is based on the GD32A508Z-EVAL-V1.0 board, it shows how to use EXMC 
peripheral to control NAND memory. This board uses EXMC_BANK1_NAND to support 
NAND memory. 
  This demo shows the write and read data operation process of NAND memory by 
EXMC module. Firstly, all LEDs are lighted on and off for test. Then read NAND_ID. 
If the operation fails, this demo will print out the failure information and 
light on LED3, otherwise print out the ID information. Secondly, write and read 
the NAND memory. If the test result is correct, LED2 will be turned on and the 
data writed to the NAND will be printed out.

  JP18, JP19, JP22, JP13 must be fitted.
