Different vendor firmware versions use different BBT table sizes. The
checksum is calculated over the entire table, so the size must match
what the bootloader expects.
The Genexis Platinum-4410 bootloader was compiled with a BBT table
size of 250 entries (MAX_RAW_BAD_BLOCK_SIZE as found in vendor code).
Without this fix, the BBT checksum validation fails:
[ 0.391948] spi-nand spi0.0: Dosilicon SPI NAND was found.
[ 0.397651] spi-nand spi0.0: 128 MiB, block size: 128 KiB, page size: 2048, OOB size: 64
[ 0.407370] en75_bmt: found BMT in block 1023
[ 0.450160] en75_bmt: BBT not found and econet,can-write-factory-bbt is unset, giving up
Add a new DTS property 'econet,bbt-table-size' to configure the BBT
table size. If not specified, defaults to 1000.
After this patch:
[ 0.407021] en75_bmt: found BMT in block 1023
[ 0.449159] en75_bmt: found BBT in block 943
[ 0.453491] en75_bmt: BBT & BMT found
[ 0.457152] en75_bmt: blocks: total: 1024, user: 943, factory_bad: 0, worn: 0 reserve: 81
[ 0.465390] en75_bmt: 117 MiB usable space
