STRUCT MARVELL_NAND_CHIP(9)

💜 struct marvell_nand_chip(9) — like, the whole vibe check on a NAND chip 💜

okay bestie, sit down, hydrate, and let me tell you about struct marvell_nand_chip from the Kernel API Manual — it's the struct that stores NAND chip device related information, and honestly? it's giving main character energy. ✨

🌸 NAME 🌸

struct marvell_nand_chip — stores NAND chip device related information 🎀

no cap, that's the whole pitch. it holds all the deets about a NAND chip device. periodt. 💅

---

✨ SYNOPSIS ✨

here's the glow-up, laid out exactly as the kernel gods wrote it:

struct marvell_nand_chip {
    struct nand_chip chip;
    struct list_head node;
    const struct marvell_hw_ecc_layout *layout;
    u32 ndcr;
    u32 ndtr0;
    u32 ndtr1;
    int addr_cyc;
    int selected_die;
    unsigned int nsels;
    struct marvell_nand_chip_sel sels[];
};

look at her. all those fields. iconic. 🔥

🦋 Members 🦋

okay so this is the part where we meet the cast, one by one — every single one of them, no skipping, i promise 🫶

• chip — the base NAND chip structure 💖 like, the foundation, the blueprint, the main character's backstory.
• node — used to store NAND chips into a list 📋 everything's in a list, bestie. everything.
• layout — the NAND layout used when you're doing hardware ECC ⚡ fancy hardware mode activated.
• ndcr — the controller register value for this NAND chip 🎛️ its personal little settings corner.
• ndtr0 — timing registers 0 value for this NAND chip ⏱️ timing is everything, iykyk.
• ndtr1 — timing registers 1 value for this NAND chip ⏱️⏱️ yes there's a second one, she's thorough.
• addr_cyc — the amount of cycles needed to pass the column address 🔄 count 'em.
• selected_die — the current active CS 👑 whoever's holding the crown right now.
• nsels — number of CS lines required by the NAND chip 🔢 how many lines this chip is claiming.
• sels — array of CS lines descriptions 🎀 the receipts, per line.
