[U-Boot] nand bad block identification

Hello,

I would like to ask if u-boot is capable of identifying bad blocks, as described in the following article in section "Recognizing Bad Blocks" (page 2). In essence, it says that we should scan the first page in each block and check if the first word in OOB is equal 0xff (if not - it's bad block).

If not implemented - Is there some simple way we can integrate it into u-boot ?

Thanks, Ran
