32 bit checksum of 508 bytes of FCB data from
offset 4 to 512 XOR with 0xFFFFFFFF.
32 bit word with a value of 0x20424346, in ascii
“FCB ”.
32 bit version number; this version of FCB is
0x01000000.
8 bytes of data for 8 NAND Timing Parameters
from NAND datasheet. The 8 parameters are:
data_setup, data_hold, address_setup,
dsample_time, nand_timing_state, REA, RLOH,
RHOH.
Number of bytes of data in a page. Typically,
this is 2048 bytes for 2112 bytes page size or
4096 bytes for 4314 bytes page size.
Total number of bytes in page. Typically, 2112
for 2K page or 4224 or 4314 for 4K page.
Number of pages per block. Typically 64 or 128
or depending on NAND device type.
Number of NAND devices present on the chip,
this is ignored in i.MX28 ROM. May be useful
for by other applications.
