 b) Initialize the SHA1 sum in the Image with 0x00
    The SHA1 sum is stored in Flash at:
-                           CFG_MONITOR_BASE + CFG_MONITOR_LEN + SHA1_SUM_POS
-   for the pcs440ep Flash:       0xfffa0000 +         0x60000 +        -0x20
-                            = 0xffffffe0
-   for the example in RAM:         0x300000 +         0x60000 +        -0x20
-                            = 0x35ffe0

    note: a SHA1 checksum is 20 bytes long.
