How to determine the System memory addresses of SPI Flash used in device running eCos operating system? For example, show flash command returns the following info:

 Flash Device Information:

      CFI Compliant: no
        Command Set: Generic SPI Flash
   Device/Bus Width: x16
 Little Word Endian: no
    Fast Bulk Erase: no
    Multibyte Write: 256 bytes max
  Phys base address: 0xbadf1a5
 Uncached Virt addr: 0x1badf1a5
   Cached Virt addr: 0x2badf1a5
   Number of blocks: 129
         Total size: 8388608 bytes, 8 Mbytes
       Current mode: Read Array
        Device Size: 8388608, Write buffer: 256, Busy bit: 

      Size  Device      Device     Region
Block  kB   Address     Offset     Offset   Region Allocation
----- ---- ---------- ----------- --------- -----------------
    0   32 0x1badf1a5           0         0 Bootloader (32768 bytes)
    1   32 0x1bae71a5       32768       ??? {unassigned}
    2   64 0x1baef1a5       65536         0 Permanent NonVol (65536 bytes)
    3   64 0x1baff1a5      131072         0 Image1
    4   64 0x1bb0f1a5      196608     65536 Image1
    5   64 0x1bb1f1a5      262144    131072 Image1
    6   64 0x1bb2f1a5      327680    196608 Image1
    7   64 0x1bb3f1a5      393216    262144 Image1
    ..  .. ........ 
  127   64 0x1c2bf1a5     8257536   4063232 Image2 (4128768 bytes)
  128   64 0x1c2cf1a5     8323072         0 Dynamic NonVol (65536 bytes)

But these addresses seems is not an actual addresses of memory locations. Because when I try readmem command, it always returns errors. For example, there is an example of readmem command:

readmem -s 4 -n 64 0x80001234 -- Reads 64 bytes as 32-bit values.

When I tried readmem -s 4 -n 16384 0x1baef1a5 it always returns error: ERROR - Address(for any addresses from above table). So I assume these addresses is not an actual Flash Memory addresses. I tnink is this because processor’s memory controller maps the flash address space to the system address space. And flash word-size differs from system word-size. So, how to find the System memory address to read SPI Flash?
