I referenced 30+ data sheets (covering 100+ parts), and I tested a 
selection of 10 different chips to varying degrees. Particularly, I 
tested the creation of bad-block descriptors and basic BB scanning on 
three parts:

ST NAND04GW3B2D, 2K page
ST NAND128W3A, 512B page
Samsung K9F1G08U0A, 2K page

To test these, I wrote some fake bad block markers to the flash (in OOB 
bytes 1, 6, and elsewhere) to see if the scanning routine would detect 
them properly. However, this method was somewhat limited because the 
driver I am using has some bugs in its OOB write functionality.
