for the default configuration:

Flash memory starts at 0xff000000 to 0xff7fffff.

see Section 5 "Memory Map" in the english version of suzaku hardware
manual for other addresses.

for the region in the flash, which is just a mtd map, as defined in
linux-2.4.x/drivers/mtd/maps/suzaku.c:


      0x0 +-------------+
          |    FPGA     |
  0x80000 +-------------+
          |    Boot     |
  0xa0000 +------+------+
          |      | Kern |
 0x210000 | IMG  +------+
          |      | User |
 0x3f0000 +------+------+
          |   Config    |
          +-------------+
