Hiya,
I don't do much PSP hacking anymore but I finally finished up my reverse of the sceNand-module and I figured out one more NID:
eba0e6c6 = sceNandCountChipMakersBBM
The only one remaining now is c29da136.
I've reversed this function and what it does is mark a block as invalid (sets the block_stat byte in the spare page to 0xf0). I tried the obvious choices of names but didn't have any luck.
Some more info about sceNand-functions:
sceNandDumpWearBBMSize is dangerous! It checks the NAND for bad blocks and perform a sceNandTestBlock on the good blocks! I suspected I did something wrong in my reverse so I double-checked and it really appears that this is what it's doing! sceNandTestBlock erases the given block and performs tests to see if it's bad. If the result is a bad block, sceNand_c29da136 is used to mark it as bad.
sceNandDetectChipMakersBBM duplicates the functionality of sceNandIsBadBlock, and simply returns 0 if the block is not marked as bad.
sceNandCountChipMakersBBM calls sceNandDetectChipMakersBBM for all blocks in the nand and returns the tally of bad blocks.
New NID for sceNand; one to go
