  * not enough free space to implement the complete I2C SPD DDR autodetection
  * routines. Therefore the Bamboo only supports the onboard 64MBytes of SDRAM
  * when booting from NAND flash.
+ *
+ * Note:
+ * As found out by Eugene O'Brien <eugene.obrien@advantechamt.com>, the fixed
+ * DDR setup has problems (U-Boot crashes randomly upon TFTP), when the DIMM
+ * modules are still plugged in. So it is recommended to remove the DIMM
+ * modules while using the NAND booting code with the fixed SDRAM setup!
