The crc32 command calculates the check sum for a memory range (from addr1 to
addr1+count). You can optionally indicate addr2 to save the calculated check sum there.
addr1+count). You can optionally indicate addr2 to save the calculated check sum there.
For example:
U-Boot> crc32 21000000 100 20000000
CRC32 for 21000000 ... 210000ff ==> e8d6cfbc
CRC32 for 21000000 ... 210000ff ==> e8d6cfbc
