STRUCT SPI_NOR_MANUFACTURER(9)

💖 struct spi_nor_manufacturer(9) 💖

okay so bestie, welcome to the Kernel API Manual — this little cutie right here is struct spi_nor_manufacturer(9), and it's literally the glow-up makeover of a manufacturer object for SPI NOR flash. think of it as the main character ID card that tells the kernel "hi yes this chip company exists, here's their whole lineup, k thanks 🫶"

---

✨ NAME ✨

struct spi_nor_manufacturer — the SPI NOR manufacturer object, no cap 💅

---

🌸 SYNOPSIS 🌸

struct spi_nor_manufacturer {
    const char *name;
    const struct flash_info *parts;
    unsigned int nparts;
    const struct spi_nor_fixups *fixups;
 };

---

🎀 Members 🎀

• name — the manufacturer's name. just the name, bestie. the whole brand identity ✨
• parts — an array of the parts this manufacturer supports. like their entire roster of chips, all lined up 💖
• nparts — how many entries are chilling in that parts array. the headcount, fr fr 🔢
• fixups — hooks that get called at various points in time during spi_nor_scan. yes, hooks. they show up mid-scan to do their little fixes, iykyk 🔧

ngl, that fixups field is the one with main character energy — it literally gets invoked at various points during spi_nor_scan, so don't sleep on it 🫶
