💖 NAME 💖

verify_bbt_descr — verify the bad block description, no cap 🫶

---

✨ SYNOPSIS ✨

void verify_bbt_descr (struct nand_chip *this , struct nand_bbt_descr *bd );

like, that's literally the whole signature, character for character, don't @ me 😌

---

🎀 ARGUMENTS 🎀

• this — the NAND device, main character energy fr 🔥
• bd — the table to verify, aka the thing getting the vibe check 👑

🌸 DESCRIPTION 🌸

so what does she actually do? she performs a few sanity checks on the bad block description table 💀 like not a full audit, not a deep dive — just a few lil sanity checks, lowkey making sure the table isn't out here acting brand new 🙈

think of it as the group chat's designated reasonable friend going "girl. are we sure about this?" before anything unhinged gets written to your flash 🌈⭐

it's literally just sanity checks on the bad block description table — don't expect her to fix anything, she's just here to look 👀
