STRUCT SPINAND_OTP_LAYOUT(9)

✨ struct spinand_otp_layout(9) — the Kernel API Manual glowing edition ✨

okay so bestie, welcome to struct spinand_otp_layout(9) 💅 this is a page from the Kernel API Manual and it's literally all about one tiny little struct that describes the SPI NAND OTP area. that's it. that's the whole vibe. she's small, she's specific, and she ate 🎀

---

🌸 NAME 🌸

struct spinand_otp_layout — the structure whose entire job is to describe the SPI NAND OTP area 🦋

like, no cap, that's the description. she's a describer. iconic behavior.

---

✨ SYNOPSIS ✨

here's the whole shape of her, bestie — keep it exactly like this, don't touch a single character 🔥

struct spinand_otp_layout {
    unsigned int npages;
    unsigned int start_page;
 };

two fields. two unsigned ints. that's the moment. 🫶

---

👑 Members 👑

npages

the number of pages in the OTP. literally how many pages there are. count 'em, queen 💖

start_page

the start page of the user/factory OTP area. so like, where the OTP area begins. that's the whole assignment and she understood it ⭐

---

• struct spinand_id(9)
• struct spinand_devid(9)
• struct spinand_manufacturer(9)
• struct spinand_op_variants(9)
• struct spinand_ondie_ecc_conf(9)
• struct spinand_fact_otp_ops(9)

go read all of them, i'll wait 💜 (jk i won't, but you should 🧚)

heads up bestie: this page lives in ./include/linux/mtd just so u know where to find her in the wild 🌸

and that's the whole page, fr fr 😭 wrote it out, nothing skipped, nothing summarized. this was the Kernel API Manual, edition October 2026, filed under ./include/linux/mtd, and she's signing off with struct spinand_otp_layout(9) one last time because branding matters 💅✨🍓
