I already finished review and test work. The BBT works well after I applied
my modification which I already sent to your by email. I tried to build a new
BBT on a new NAND and then mark one block to bad. Both works well.
My test platform is Xilinx Zed board.
I will try to rebase my SPI NAND patch on your patch and send it out.
It will take me some time because I'm quite busy with other company affairs.
