Log:
Bug: N/A
Description:
Added nandc command to print crc32 of each flash block. For example:
JIVE# nandc 0 28000
Block 0 (0x0) = 0xcfc19b7c
Block 1 (0x1) = 0x2faf1899
Block 2 (0x2) = 0x84c2f57a
Block 3 (0x3) = 0x292eee9c
Block 4 (0x4) = 0x6bac5e1
Block 5 (0x5) = 0xcf7dfe8e
Block 6 (0x6) = 0x571c22a
Block 7 (0x7) = 0x41b0b63c
Block 8 (0x8) = 0x690b37d3 ERASED
Block 9 (0x9) = 0x690b37d3 ERASED
