+ * varname            (default)       note
+ * IPSBAR             (0x40000000)
+ * MCF_CFM_CFMCLKD    (0x1D0002)      ipsbar offset

+ * FLASHBAR_REG       (0x0C04)
+ * FLASH_SIZE         (256 * 1024)
+ * FLASH_BACKDOOR     (0x04000000)    ipsbar offset
+ *
+ * NOTE: The target and flash clock must be setup to the correct flashing
+ * frequency prior to invoking this flash algorithm
+ *
+ * NOTE: Flash detection simply checks flashbar, so flashbar must be configured
+ * prior to calling flash_register
+ *
+ * NOTE: Flash addresses and write memory sizes need to be 4 byte aligned!
